Re: Adjusting the Voltage Regulator

Dear Fory:

Intermittent charging is generally due to worn brushes. Or a bad connection. The armature spins for a while and starts charging. Over charging or undercharging means the average voltage is too high or too low due to poor regulation.

A regulator can be checked for opens with an ohmmeter, but if a resistor opens it stays that way. When a resistor is going bad it charges for a while then stops, but is not intermittent.

I did a Twin Six with such a problem and one of the of the wires on the brushes was loose. A little metallic epoxy solved the problem. They had been putting all sorts of regulators on it over the years.
