Hi Daybreak That was a great read thanks for taking the trouble to post it. It helped me a lot Best Mike

Howdy,
The information is still current and useful

It's a good article, but the advice it gives about regulators is not correct, as it applies to the MEP-002A and MEP-003A. In these generators, running the engine below operating speed lowers the generator output, and the regulator sees this and tries to raise it by lowering its output current, not raising it. This is because the output of the regulator goes to the control windings of CVT1, which is a special magnetic amplifying transformer. CVT1 is what supplies current to the exciter field, after being rectified by the diode bridge, and it reduces this when current is passed through its control windings. The regulator works least when the engine is running slowly, and most when it's running at or above operating speed.

I've verified this by adding a regulator output current meter to the control panel of my 003A, so there is no doubt.

Triple Jim,
You hit it right on the head! This info should have been printed on the side of the control panel.
