Generator 12 or 6 volt

jgstrickland · Jun 25, 2013

Hello again,

I am getting closer to finishing up a 1948 Cub and I am at the Generator now. I just purchased a Generator for it with the brackets. It's a Delco Remmy 1101355 8G14 and I am getting a 14v reading off of it. I thought that they were 6V Gennys. Is it possible that someone wired it 12v?
It does have a cut out on it and I have cleaned all the grounds and all the coonections and ran emory cloth through the contacts on the cut out as well. I have a Magneto on the the tractor and jump start it with a 12v battery for now until I figure out which way to go. I disconnect the battery after starting the tractor. What is up? Do I have a cross breed genny or what? Is it working right for a 12v system if so I will go 12v.

Thanks
James

If your system does in fact use a cutout rather than a voltage regulator you may be very lucky that you only had 14 volts after disconnecting the battery.

The battery acts as a voltage control in a system that uses a cutout rather than a voltage regulator. In a system without a voltage regulator there is no voltage control other than an electrical load that uses the amperage that the generator provides. Once you remove the battery the recharging load is gone and there is nothing to limit how high the voltage will go. Usually that limit is reached when the voltage becomes high enough to create a short circuit.

That generator number is correct for the original 6-volt cut-out based charging system. Now that you have used emery cloth on the cut-out contacts it will probably fail before long. You might be able to save it by recleaning the contacts with a point file then cleaning them with contact cleaner while holding them open. Otherwise plan on buying a new one. You have a fair chance if it is only a cut-out. If you used emory cloth on voltage regulator contacts, you might as well drop it in the trash now.

What batt is hooked up when the engine is running should be 6v with pos gnd. You dont run a gen without it being hooked to a battery. Your gen # is 6v unless it has been changed to 12v better take to a gen shop for a check.

The reason emory cloth ruins the cutout is because it leaves fine granules of material embedded in the relatively soft metal that the points are made of.

So which battery does it take a 12v or a 6v?
