Hi John:

Okay, let's get down to some garage mechanics to sort out your problem.

The only way for the ammeter to peg positive is if either the generator is full fielding, or the gauge is hooked up backwards and you have a short circuit.

I will rule out the later because you said the thing was fine and the went haywire.

So go to your generator and you should have three wires:

a) a large red one on the heavy post - armature
b) a small tan one on the small post - field
c) a small black wire screwed to the generator - ground

Disconnect the tan wire. If the problem goes away you have a short circuit between the generator and the regulator in the tan wire.

If the problem persists then you probably have a shorted field winding in the generator and the unit will need to be repaired.

I wont concern myself with the other phenomenon because it is too wierd. I assume you are using a 6-volt battery.
