A generator is basically a motor in reverse, the only problem is you need
higher revs to keep the regulator charging, so unless you keep your foot on
the pedal it will not charge at idle (watch the red light on the dash).
Alternators will charge at much lower speeds, - one of their benefits.
Therefore at idle your battery will not be charging but trying to keep your
ignition circuit running.



Hopefully your problem is just the load created by a poor battery or
connections to it, otherwise you will need to check the regulator and sets its
contacts (regulator acts as a relay to switch the current on and off to feed
the battery as well as the other circuits). May be worth checking the brushes
in the generator as well, may be quite short in length after 40 + years.



cheers Andy
