beavis9574 :

sounds like you have a bad diode in the alternator, if its a generator unit, problem it may be a problem in the voltage regulator as well. to test this, completely remove the wires for the charging system from the starter solenoid, or the battery (whichever one they go to

beavis9574 :

then hook up your booster to the battery, crank and go, leaving the booster hooked to the battery. it should stay running provided you coil power wires are still hooked up.
