My generator won't charge a dead battery, it has field windings, and
unless you put
12volts to the windings, it only puts out 1.5volts.
Do use a good battery for checking gens./atls. and save yourself some 
aggravation.
Does anyone know about voltage regulators ? I have a 71 midget with a
generator,
the regulator has three coils that are adjustable. I'd like to know what
each is for, and
how to set them ( gen light comes on at an idle since I cleaned the
contacts )
