Default Re: Generator wiring

The battery connection to the starter is the basic electrical buss on a stationary industrial engine. The coil and the ammeter would be the only other circuits if no accessories are utilized. The ammeter connection was already mentioned. Wire from cut out to ammeter and then a return wire to the starter switch. The coil can be wired in with the ammeter through an ignition switch or direct depending on whether a person wants to switch the hot side of the coil or the negative. The switch can also be connected in the ground side of the coil between the coil and distributor like Ford did it originally. It will work either way.

Make sure the generator pole shoes are polarized for the way you have the battery connected, ie positive or negative ground. If the ammeter starts showing a good discharge after start then try swapping when two wires connecting to the ammeter. The generator 3rd brush can be adjusted to give at least 5 or 6 amps.

I would warn anyone that runs an engine without a load that it may develop compression problems if the intent is to break in an overhauled engine. I wouldn't run one more than 30-minutes without a load on it.
