I feel Im a nice guy so here you go....It does involve reading, PM me your number in case you need it read to you so you can understand...Q#19:What is a "voltage regulator" and what does it do?
A#19:The voltage regulator is a small, square, silver box with a single (usually blue) wire coming out of it leading to the wiring harness. It is mounted just to the right-hand side of the CDI under the rear fender, and typically one of the 12mm mounting bolts has an eyelet terminal with a black ground wire going to the wiring harness. The voltage regulator is NOT part of the ignition system, but part of the lighting system. It's purpose is to regulate voltage (you don't say) to the lights, preventing them from blowing because of too much voltage. The voltage regulator on a Banshee limits voltage to 12 volts no matter what RPM the motor is at, since the higher the RPM the more voltage the stator will produce, the voltage regulator prevents the voltage at the light bulbs (and the wiring harness leading to the light bulbs) from exceeding 12 volts. As you've no doubt witnessed, at idle or low RPM, the stator's ignition coil does not produce much voltage, as the lights are real dim. When you wind it out they light up pretty well, but if it wasn't for the voltage regulator they would burn out quickly from the higher voltage.
