If there’s an electrical problem on your motorcycle, stay patient and use logic. Generally, readings above 17 volts mean the regulator rectifier is not converting excess power. Built in relay activates switched 12V DC output line only when engine is running, with adjustable shut-off delay. For the most part, motorcycles are on a three-phase system for efficiency purposes, where three wires connect the stator and regulator rectifier. $29.99 $ 29. Regulator/rectifiers for 6v Models. The power that is generated from the alternator is 3-phase AC voltage. Without a functioning rectifier-regulator, a weak, dead, or overcharged battery would be the result. Although relatively simple components, after 40-50 years of vibration and exposure, the voltage regulator and rectifier are ripe for replacement. One motorcycle part, the regulator rectifier, generally gives some additional signals that it is not operating correctly. This explains why it is the most commonly used system on motorcycles.One of the problems with these systems is the short-circuiting of the excess power itself. This page will help you track down your issues. You can measure voltage drops in your wiring harness and electrical system by connecting the positive lead of a multimeter to the positive lead of a battery and the negative lead to the component of wire you want to test. It is a fact of life: parts will eventually go bad. How to Test a Motorcycle Rectifier The motorcycle’s rectifier is another part of the charging system. If the voltage drops below approximately 13 volts, the motorcycle will begin to drain the battery and eventually the engine will stop. If your starter motor is the issue, you’ll need to take it out to service it. Refer to your manual for the exact resistance specifications. The Regulator Rectifier. Fit either a Zenor diode or remove the rectifier and fit a regulator/rectifier unit (A Reg One) These are more reliable, more efficient and easy to fit. Here is a picture of a Lucas alternator rotor (the magnetic bit in the middle) and stator (the bit round the outside with the wires coming out of it) Also able to upgrade charging systems on other models by replacing individual regulator and rectifier with a single-unit that simultaneously regulates and rectifies the total stator output. This page will serve as a starting guide to get you started troubleshooting electrical problems on your motorcycle. 50W full wave regulator/rectifier for DC electrical systems.

In this system, we see that one end of the winding is grounded to the chassis of the bike, which is connected to the negative terminal of the battery. There should be no continuity between the three wires and the ground wire. Inspect the harness for frayed wires, broken wires, or wrong connections. If it works, there is likely an issue with the large cable the connects the starter to the solenoid and/or the solenoid itself. Universal Regulator/Rectifier by Trail Tech®. 2) 3-pin Regulator: This type may be found on some motorcycles. Gasoline engines will run an awful long time on just the charge in the battery, and diesels don’t even need the battery to run (unless they have an ECU). Depending on the design of your engine, you may need to remove a side cover to get to it. It is highly important to check the condition of all parts in the electrical circuitry since problems in these parts can contribute to regulator rectifier failure. If it’s too much less, the battery won’t charge at all. If the solenoid clicks when you hit the starter button, but nothing happens, it could be damaged on the inside. This is done by the regulator-rectifier and this part has to dissipate the power that it shorts to ground, meaning it will get very hot. ... People writing from Australia use the word cactus as an adjective - perhaps describing a failed motorcycle part, or the whole bike, so my interest was piqued. There are different reasons why the regulator rectifier fails. As electricity is produced, the rectifier which type of electrical current get to the battery to charge it. There are typically 3 wires of the same color and a ground wire that come from the stator. For those that want to ride there vintage British motorcycle and make your electrical system "bullet proof" a … Measure the continuity/resistance between the wires of the same color. A better type of rectifier circuit uses four rectifier diodes, in a special circuit called a bridge rectifier. Order your motorcycle’s official shop manual at eManualOnline.com. Rectifier or stator problem. Clean out any carbon buildup and oil. How to:diagnose motorcycle problems Battery.

A half-wave rectifier is used to supply 50V d.c. to a resistive load of 800 Ω. 15. The DC voltage is then routed to the battery. The problem may not be from overheating, but from a manufacturing defect. It can also help to clean all of your motorcycle’s connections with electrical contact cleaner. ). It should be between around .5 to 3 Ohms. The bridge rectifier animation highlighted, shows a simple bridge rectifier circuit that is used in motorcycle regulator rectifiers. The stator is part of your motorcycle’s charging system. Ground Wires. Next, reverse the leads of the Ohmmeter and check the readings again. Modern motorcycles have electrical charging circuitry for the battery, of which the regulator rectifier is a standard part. You can bypass the solenoid by bridging the posts with a screwdriver. You’ll just need to get yourself a good ohmmeter/multimeter to track down what needs repair or replacement. Sometimes, you’ll find that nothing happens when you hit the starter button. - regulator/rectifier section If that was gibberish, then here's a good testing algorithm: If your stator coil was producing the right voltages in the tests above, but the voltages at your battery seem off (e.g. Take it apart slowly, as there are small pieces that fit together in a sequence on the inside of the motor. Before you start doing any electrical testing, make sure your battery is fresh and fully charged. It may also be that the starter button housing is corroded and it is not getting a solid ground when it is depressed. Connecting the rectifier - Disconnect the 6-position, 5 wire connector from the OE rectifier & plug the identical connector on the 10-100 in its place. Some motorcycles are known to have the part located near the radiator or other locations that are either close to heat producers or restrict air flow. Affecting 73,426 motorcycles from various product lines and model years (2008-2010), Suzuki has discovered a faulty electrical rectifier/regulator in its design that needs replacing. Even so, there are some single-phase systems available as these are cheaper to manufacture, but the system uses two wires instead of three. Check continuity between connections. A great place to start is at the source of power. If it’s more than than, the battery will overcharge. Overtime, o-rings and seals can break down, which allows oil and grime to enter the starter motor and foul things up. Depending on the location of the regulator rectifier, the part can easily overheat. Motorcycle Rectifier/Regulators. If the reading is less than 12.6 volts, then there is a voltage drop somewhere. In 2007 Dani Clark became a published writer with the acceptance of a poem into a poetry anthology. It is easy to assume that the issue is a bad battery because of symptoms such as dimming headlights, irregular meter readings and poor starts. Repeat for all wires. To test the rectifier, connect your Ohmmeter to one of the wires and the ground/mounting stud of the rectifier and record the reading. A full-wave rectifier uses two diodes, the internal resistance of each diode may be assumed constant at 20 Ω. Mjm. Look at how this rectifier works on both sides of the alternating current input signal: In the first half of the AC cycle, D2 and D4 conduct because they’re forward biased. Moreover, even after the part has failed, check its internal connections. If there’s not continuity where it’s supposed to be, you’ve got a short. Next test the resistance between the spark plug wire and the ground. To this day I have not heard or seen a failed Podtronics unit. 05 Jul. If any one of them has a reading that is too close or if there is not continuity, the rectifier may be bad. Next, check the starter solenoid.
