There are two differences between them and they are very serious. •The rectifier needs to be unplugged with no voltage running through it. Voltage Regulator Rectifier Units Oregon Motorcycle Parts. I would recommend you to try with a BJT first, such as TIP142 and see how it responds, if it responds well then the problem could be specifically with the mosfet. The best comparison - the toilet water tank. Each diagram includes the part and associated parts all in one wiring diagram. Car Warning Tone Generator for Ignition, Headlight, Turn Lights, Customizing Car Side Marker Lights to Flashing Side Markers, LED “Halogen” Lamp Circuit for Motorbike Headlamp, Simple Ignition Code Lock Circuit for Automobile Protection,,,,,, Small Signal Transistor(BJT) and Diode Quick Datasheet. according to the spec, gate voltage is +- 20V and maximum continuous drain current 30A. The regulator/rect takes in from two coils, one wire directly from the charging coil and then a braunched wire from the lighting coil to shunt off any extra voltage as to not blow the AC headlight. Same here bro..zener burns out and output becomes very low..but when input voltage is lower than the zener output is same as input.. Sir i cudn't find BTA26 600, i find BTA 41 it can apply this tell me now thanks. passing high amount of current to laod also heats the rectifier thou. I like the circuit design above because the simplicity. Would you please provide some explanations in favor of your remarks. It also becomes very fluent unlike it is at the start of reaction. I only ever read that the regulator runs cooler but nothing mentions effects on the stator. The most common failure of VR is the failure of one of the diodes, ie breakdown of any diode. English is not my native, so I ask you to treat any mistakes indulgently. The objective of any voltage regulator - to receive a voltage and lower it to the certain desired level and hold it at that level. Product name JH125 RegulatorApplicable Motor JH125 WY125-A GY6 DY100Characteristics1. My wires are 4, this is approximately 3 mm diameter for multicore wire. Anyway, in other case you can skip it or move to Step 3. Usually, it is easy to determine if you know where generator is located. Motorcycle VR regulates the output voltage of the generator. Suit yourself depending on your power consumption (Xenon lights or heat bulb, onboard music, etc.). For further understanding of the text that's enough. Never did much with FETs because when they first came out, the least little static charge would blow them out in a heartbeat. This is because the connected 12-volt electrics will pull more current from the regulator rectifier to compensate for the reduced voltage. Is it because I connected the drain to input voltage by hand not making it fixed thus making some sparks which lead to damaged mosfet. now I get confused, it is working as expected in this page with input voltage easily swing to more than 100V with full engine rpm. This will give you an opportunity to check temperature first couple of days, and will give good cooling airflow through the heat sink. So according to me the transistor will be completely switched off until the voltage from the dynamo exceeds 14 V, otherwise the whole idea of voltage regulation will fail. Water flow is high, the valve is opened and pouring out the excess water. Auto VR adjusts the voltage on the field winding of the generator.
