Should I always have battery power at the generator terminal with the car off?

I've completely rewired the car, rebuilt the switch, replaced the generator, and installed a Fun Projects VR. I installed the 6V battery today and with switches off and key removed, I have battery power at the generator terminal. Is that correct?

Yes.

Best, fastest, most concise answer ever on the forum - thanks, Frank!

You should have 6 volts at the cutout terminal where the wire is connected, but not at the terminal on the generator at the other side of the cutout. That is the purpose of the cutout to allow current from the generator to flow toward the battery, but cut off the battery from the generator when the generator is not running. either a cutout or a voltage regulator will cut off the battery from the generator when the engine is not running.

Frank, I'm afraid the correct answer is NO
There will be battery power at the front terminal of the cutout.

True Tony but the way I interpret John's question was for the wire being live up to the cut out, other wise his question would have been.

When I turn the key off why is my generator and cut out smoking?

The key on or off has no effect on the generator wire. The cutout will disconnect the battery from the generator output terminal when the generator stops producing . The wire to the cutout is always hot and when the generator starts producing electricity it closes the cutout and the generator output flows to the battery. Help??? There is a good wiring diagram posted close to this post somewhere. As stated, the hot wire goes to the end of the cutout, not to the generator output terminal.

Sorry about the repeat.
