tend to agree with Tauno Voipio, a series regulator will simply move. In the most basic terms it consists of two electrical contacts (switches) which are opened and closed (turned off and on) by two sets of solenoid coils. The basic components of your motorcycles charging system include the alternator, stator, and regulator/rectifier.
The transistor is wired as an emitter follower so the voltage at (4) will be V 4 = V 3 - 0.7 V due to the base-emitter voltage drop. Since this is usually a permanent magnet alternating system there is not field windings to control alternator output and so the alternator is engineered to produce a give voltage and current for a given rpm range, Excess voltage is usually produced and the regulator bleeds this excess of to ground through semiconductors when it reaches a
It works by directing the current away from the load and sending it into the ground. 
This overcharge is a stress on the battery. A voltage regulator is a device that maintains the voltage of a power source within prescribed limits. Symptom A: Dead Battery. I have a vintage motorcycle (1934 Levis 500cc model D) with a BTH mag generator which I have just fitted. Yes, the power does increase as the rpm increase, but the Voltage across the regulator is usually less than 2V; because of the low Voltage, the power dissipated is corresponding low. The regulator senses battery voltage, and regulates current flow to the field coil. When the battery voltage is low, the regulator allows maximum current to flow through the field coil, increasing the magnetic field in the rotor. You can see from the diagram that there are only four main components to the Lucas charging system if we ignore all of the switches, bulbs and other accessories for the time being.
They also have a built in error amplifier, which samples the output voltage (again through a divider), compares it with the reference voltage, calculates the difference, and drives the output I am working with the following circuit from a motorcycle. Charging systemswhich are comprised of your motorcycle's stator, alternator, battery, and regulator/rectifierare the proverbial redheaded stepchild of motorcycle maintenance.
This useful device keeps the output voltage at the same level even when loading conditions or input voltage changes.

If the reading is higher, this means the battery is overcharged and you may need to replace the regulator rectifier.
In this thread, my focus is only on the the second part i.e.
have (50V-12V)*15A = 570Watts. A regulator. Ensure your multimeter is on the voltage setting . They generally fail in older bikes as resistance builds up in the loom, so many people like to put a new one on a custom build, but you need to remember to check the alternator cables and connectors are healthy too. 2. Where is the regulator rectifier on a motorcycle? The voltage regulator controls how much current gets to the battery so that it doesnt overcharge. By changing the resistance of the series element, the voltage dropped across it can be varied to ensure that the voltage across the load remains constant." Battery Comes Up Short. With everything plugged in and the bike running the output to the battery should be above about 13.3V at idle, increasing to about 14.5-14.8V when the rpm is raised.
the heat to a different device. It is capable of taking an input voltage between 20V and 250V, and improves the ability of the motorcycle to use modern, higher-power lights and to charge devices like phones as well. It has a very low efficiency but since the wasted current has a very low value, it is neglected. Charging systemswhich are comprised of your motorcycle's stator, alternator, battery, and regulator/rectifierare the proverbial redheaded stepchild of motorcycle maintenance.
Since the feedback signal (2) is close to zero and the reference voltage (1) > 0 the op-amp output (3) will start to swing towards the positive supply. Ever wonder how a motorcycle works? The SCR is very slow to switch, and requires lots of electrical current to complete the switch, resulting in lots of heat and variation in the battery voltage. Our guide will show you how to deal with the Lucas MCR2. The control monitors the output voltage of the voltage regulator using voltage information from a potential transformer.
How does a motorcycle voltage regulator work? A shunt regulator does not short to 0 V. Here **broken link removed** is an example of a shunt regulator and it's clearly not 0 volts. Overcharging the battery can cause if to overheat and damage itself and other electrical components. The voltage regulator comes in two types: linear and switching. It provides 13.8V DC out from a 15V-100V AC generator input.
The main differences are in switching speed and heat generation. This, in turn, increases the output from the stator windings. regulation of the AC voltage. The first one is mostly used for small bicycles, while 3-pin ones can be found on some bikes. Symptom C: Flickering Or Dimming Lights. Burnt ign.
Other than the possibility of damaging a regulator the answer to the question is no. Mike711. In fact I suspect a simple series regulator may produce more heat if the alternator can output 15A AT 50V, for dissipation, you would. The dynamo is a small permanent magnet DC type, but chucks out about 6v at tickover rising to about 15v when revved. The rectifier is part of the charging system. If you put a freshly charged battery in your motorcycle, and you have a bad rectifier, it wont stop your motorcycle from starting, but your battery wouldnt stay charged. The regulator/rectifier on your motorcycle performs two functions.
What is a Voltage Regulator and How Does it Work. Answer (1 of 2): You should notice issues with low battery voltage for one, also headlight may dim things like that. Since this is usually a permanent magnet alternating system there is not field windings to control alternator output and so the alternator is engineered to produce a give voltage and current for a given rpm range, Excess voltage is usually produced and the regulator bleeds this excess of to ground through semiconductors when it reaches a The first part (the yellow box) converts the AC voltage from the generator to regulated 14.4VDC to charge the battery. Regulation is done by the regulator -part of the regulator -rectifier. It is capable of taking an input voltage between 20V and 250V, and improves the ability of the motorcycle to use modern, higher-power lights and to charge devices like phones as well. Symptom E: Malfunctioning Instrument Cluster. It is optimized for use with motorcycle alternators and allows for producing high current even at relatively low RPMs. Fuel Pump Regulator for Harley Davidson Replace OEM # 27408-01 58 PSI. Updated: August 11, 2019. Symptom D: Battery Light Or Check Engine Light Activating.
The second part (the green box) converts the AC voltage (12-50V) to regulated AC voltage (12-14V) for Lamps only. The alternator system on a motorcycle consists of a few separate parts, including: A stator. These regulators use diodes to switch the current, making them slow and creating a lot of resistance within the voltage regulator rectifier, ultimately generating a lot of heat. This Article Contains: 5 Bad Voltage Regulator Symptoms You Should Watch Out For. In this series we delve into the workings of the thing we all love to ride.
The following are the most relevant symptoms of failure in the regulator of a motorcycle:The engine of the motorcycle stops running. The motor of the motorcycle does not start or develops a poor start. The battery overheats. Control panel failure. The motorcycles short and long range lights flash or do not come on. Excessive internal temperature of the regulator. Abnormal engine noise (cylinder failure). Switching on the electric fan. More items Most of the posts so far in this thread are a little bit off. There is clipping say in an audio amplifier that's unwanted. The rectifier is responsible for converting AC power to DC power and then storing this power in the battery.

A short battery is a sign of a damaged rectifier regulator.
The dynamo is a simple direct current (DC) generator which is driven by the engine. Take the stator side of the harness and check for continuity to ground for each of the three wires.
Answer (1 of 2): You should notice issues with low battery voltage for one, also headlight may dim things like that. Motorcycles are usually equipped with permanent magnet AC generators. It's used to regulate voltage levels like one or more AC or DC voltages. A MOSFET regulator uses its namesake, a Metal Oxide Semiconductor Field Effect Transistor to do the switching.
The alternative is to remove the innards and replace them with a cheap and simple solid state rectifier. This sends current to each gate of the three SCRs S1, S2 and S3, via current limiting resistors R3, R5 and R7. Step 1: Set The Multimeter To Voltage. The network C1, R1, R2, ZD1, D1 and D2 forms the voltage detection circuit, and it is designed to trigger at about 14.4 volts. The basic components of your motorcycles charging system include the alternator, stator, and regulator/rectifier. Brand Value: Every brand of voltage regulator for harley has a value all its own.

Take a look and see if you want to totally preserve the originality of your classic bike, or if you'd rather update this aspect of the charging circuit with a discreet modern component. The voltage setting often looks like V or a V with a few lines above it. Step 1: Set The Multimeter To Voltage. Measure between the base of fuse 6 to the 30 contact of R3, it should be ~ 0.5 Ohms each time you turn the switch on. You can only charge the battery with a rectifier and regulator. After work, started bike and it did a half start and died, started up (hesitantly) 2ND time. In this video, I probably demonstrate a method to troubleshoot and repair a 12 volt charging system's voltage rectifier regulator. As soon as charging system passes this threshold voltage, T1 starts conducting. There are primary two functions that are performed by the Rectifier on the bike: It converts the AC into the DC. I need a voltage regulator for this machine to avoid blowing all my bulbs and frying the battery. The voltage regulator, as it names suggests, regulates the fluctuating voltages supplied by the dynamo into something more usable by the motorbikes electrical system. If the regulator is not right, usually they will cut charging voltage back a lot and possibly down to 0 to recharge the battery. If this function is not fulfilled, faults may occur in the regulator itself or in the other related components.
I believe your 690 has a permanent magnet alternator and a shunt type regulator. If its allowing alternator to put out over 15 volts; it can boil battery dry, burn out solid state components (including ECM if you have one), ignition modules (if not Kettering breaker-points); and switched on lamps. Take a look and see if you want to totally preserve the originality of your classic bike, or if you'd rather update this aspect of the charging circuit with a discreet modern component. Engine Voltage Regulator, Voltage Regulator 12V Motorcycle Engine Rectifier Interference Proof Waterproof Motorcycle Voltage Rectifier for 400 EGS E LSE RXC E EXC in Voltage Regulators. LordOverThis is talking about field coils and assumes that you have an excited field system, but I don't believe you do.
Motorcycle Cruiser. It is also attached to a voltage regulator that regulates the power generated by the AC generator, or we can say the Alternator. Learn more about the fundamentals of voltage regulators here. A voltage regulator is a circuit designed to create and maintain a fixed output voltage, regardless of changes to the input voltage or else load conditions. Most voltage regulators are also rectifiers.
It is also attached to a voltage regulator that regulates the power generated by the AC generator, or we can say the Alternator. Starting a motorcycle requires the battery to be working properly, so a bad rectifier will prevent your motorcycle from starting. To check the regulator, connect the meter leads to the bikes battery as its running. 2- start the car and look at the voltage on the voltmeter, it should read 13.8 14.2 after stabalizing. A rectifier.
4-if it reads 12, unplug the regulator and jump from the battery to the field terminal. If the regulator is not right, usually they will cut charging voltage back a lot and possibly down to 0 to recharge the battery. However, a bad battery can keep the Voltage lower than this, so start with a known good battery; have yours tested at a battery or auto parts store.
The voltage setting often looks like V or a V with a few lines above it. First of all carefully prepare the layout depending on the The control then sends commands for operation of the tap changer to boost or buck the voltage and maintain the distribution system voltage within a specified band. Presently, there are two main voltage regulator rectifier technologies; the older Shunt type which is used by most OEMs. around 13 volts, the bike will start to drain the battery. When this happens, its only a matter of time before the engine stops completely. The other way that your regulator rectifier could fail is when the shunt regulator burns out. If the regulator rectifier cant moderate the voltage levels, the battery will overcharge.
In this system, the voltage regulator controls the strength of the electromagnet, and the rectifier converts the stators AC output to DC for the vehicle. Nos Bultaco Sanhuan Voltage Regulator Smt125d0004 49-06-003v. Car Alternator. You can utilize a voltmeter right here also; analyses over 17 volts mean that the rectifier is not transforming the excess power.
Parts of a Motorcycle Alternator. Meanwhile, if it consists of the high voltage, it will cause the lamp to break. Stators can be found in many configurations, with single-phase and three-phase being most common, though some (especially on older vehicles) may have separate windings for multiple systems. A shunt regulator when the voltage is below it's threshold does nothing. This regulator assists handle and also control the voltage. Max output voltage for an unregulated alternator at wide open throttle (WOT) is 16v; if regulated usually 14.5 is max.
It seems that they would turn on almost immediately. A Motorcycle Voltage Rectifier Regulator gives your bike the electrical current it needs to meet demand, at the right voltage. The alternative is to remove the innards and replace them with a cheap and simple solid state rectifier. Semantics, of clipping makes sense when you try to describe it. Location Bm8-17l Bag5. If the voltage is not controlled, it will lead to battery overcharge. I understand how the bridge rectifier (BR1) and smoothing capacitors (C1, C2) work, but I am not clear how the SCRs are being used for regulation in this situation.
JUST WATCHED. Ensure your multimeter is on the voltage setting . 1-fully charge the battery and hook a voltmeter to it, it should read 12.5-12.8 volts.
There are primary two functions that are performed by the Rectifier on the bike: It converts the AC into the DC. Bubba is right, it is almost certainly a poor R/R that is frying your stators. A Motorcycle Voltage Rectifier Regulator gives your bike the electrical current it needs to meet demand, at the right voltage . It is driven by the engine itself and has a built-in rectifier, and a built-in regulator, just like a car-generator.The only connections to it are the positive output-lead to the battery-plus and a supply-lead from the ignition-switch to the regulator inside, so the regulator can be turned on and off when the engine is not running, and it can sense the voltage on the bikes electrical system The stator in a 4-pin voltage regulator has two windings. The reading should not be higher than 14.5 volts or lower than 13.5 volts. coil primaries, fried points.
Updated: August 11, 2019. Set it to 20V. Symptom B: Erratic Engine Performance. The charging system gets its ground from the wire the back of the alternator. That is what a voltage regulator rectifier does. The function of a motorcycle alternator and alternators found on other vehicles is the same. The voltage at (5) will rise and this feeds back to (2). Answer (1 of 10): A rectifier on a motorcycle does the same thing a regular rectifier does: It converts alternating current to direct current. Regulator rectifiers give your bike the electrical current it needs to meet demand, at the right voltage. If you want to get a reliable, steady voltage then a voltage regulator will be a preferred device. Motorcycle Alternator vs. Motorcycle Cruiser. Preparing the Layout. Most voltage regulators are also rectifiers. It provides a path from the input voltage to a variable resistor which is connected to the ground.
The following information is strictly for the Magneti Marelli injection system.
How does a motorcycle voltage regulator work?
A shunt regulator is used for low-powered circuits. false, the "average" motorcycle charging system is 300w.
A healthy system should maintain 13.5-14.5 volts with the engine running, anything greater than this will show the impending failure of the regulator . A series regulator is: "The series voltage regulator or series pass voltage regulator uses a variable element placed in series with the load. The case to the voltage regulator is not grounded, it makes zero connection to the caseso it wouldnt matter.
If the rectifier regulator is normal, the current and voltage sent to the electrical components will be normal and not excessive (leaky). A voltage regulator is basically a beefed up emitter follower, like described above a transistor connected to a stable reference that spits out a constant voltage, dropping the rest. I guess that depends on the size of the bikes you consider 'average'. The grease inside the switch goes hard after a few years and it holds the contacts apart. A stator looks like a round, woven coil of wires, and it sits around the magnets connected directly on the flywheel. Make sure to only lightly touch the connector terminals. The magnitude of the voltage produced by these generators depends upon the RPM of the engine. This article describes a home-made voltage regulator for Bosch charging systems, with a cost of less than 10 Euro for the parts. Answer (1 of 2): Depends. Testing an alternator regulator with your multimeter set to Ohm or Amp can damage your device. 29-8-2020 Voltage regulator XB 2008 -2010 models 18-11-2020 - New Voltage Regulator from Twin Motorcycles for Testing an alternator regulator with your multimeter set to Ohm or Amp can damage your device. Set it to 20V. Nos Bultaco Sanhuan Voltage Regulator Smt125d0004 49-06-003v .
Where is the bad ground on a motorcycle? Voltage regulators can be divided into 2-pin, 3-pin, and 4-pin ones. Mine dropped from anywhere from 10 - 16 Ohms down to a consistent 0.5 after cleaning.
To do that, touch one lead of the multimeter to battery negative (-) or any bare metal part of the motorcycle, and the other lead to each of the wire terminals. Without the rectifier and voltage regulator converting the variable voltage AC output of the alternator to a usable 1214 Volts DC, the battery will not be re-charged or be able to keep up with the demand of the ignition system and any lights or accessories that are switched on. Motorcycles are usually equipped with permanent magnet AC generators.
The regulator is usually located under the vehicle chassis at the front of the engine, and another function is to convert AC voltage (alternating current) to DC (direct current). It senses the voltage in the bike selectrical system and when the voltage is lower than 14.4 Vdc it switches on the field (it switches a 12Vdc supply across the sliprings) Then there is a magnetic field, so the stator will produce power.
