Re: Adjusting the Voltage Regulator

The regulators usually have a metal strap that connects ground around one of the mounting screws.

There should be a wire in the harness from the frame of the regulator to the generator for ground.

Some regulators have adjustments for the voltage and amperage relays. Some have slots in the contact mounting so they slide some you have to bend.

The better regulators have temperature compensation that cuts the charge voltage in hot weather to prevent boiling the battery. in cold weather it can be about 7.5 volts but as it warms up it will drop to 6.5.

Use an accurate voltmeter. The voltage relay points vibrate continuously so be careful if you tinker.

Some can change a little by just removing the cover.
