Re: Ammeter Shows No Charge
To test the generator, remove the cutout to take it out of the system. The remove the fan belt. Then run a hot lead to the generator terminal and it should turn like a motor but slowly.
To see if the generator is generating, run the engine at a fast idle and measure the voltage at the generator terminal, the opposite side of the cutout from where the wires hook up. It should register about 7 volts for a 6 volt car and about 14 volts for a 12 volt car. If it is 6.2 volts or less for a 6 volt car it is not generating. If it is much higher than 7 volts for a 6 volt car then the cutout or the wiring is bad and the generator is not connected to the battery. Do not run the engine for more than a couple minutes with the generator disconnected from the battery or it may burn out.
The voltage at a fast idle should be the same on the wiring side of the cutout. If it is at the battery voltage then the cutout is likely bad.
