9N quit charging

The ammeter just went from reading plus to reading negative. In troubleshooting the problem, I'd like to know the function of the cutout relay & how it operates. When are the contacts open & when are they closed? What will jumping it do?
 
The cutout relay is a switch that connects the generator to the
battery when the generator is working so the battery can be
charged. When you shut the engine down and the generator
stops charging the relay opens or "cuts out".

Jumping it while running, at least temporarily as a test, is the
same as it's normal operation. If the generator is working the
ammeter should show a slight charge on a good battery.
Don't leave it jumpered after the test.

Thanks for that explanation! Now, to continue---my wiring diagram shows one wire going from the switch to the generator and another wire goes straight to the battery. So, is the diagram missing a third wire to energize the relay with the case being the ground?

No third wire, the wire from the generator is what energizes the cutout relay.

Thanks---that's just about all there is to know about the relay & its function.

Yes sir, pretty simple device. There is an adjustment on the
back of the generator to turn the charging rate up or down.
Turn it up while running lights if needed, or if running short
time durations. Turn it down if you run it for long periods or
the generator can over charge the battery and boil it "dry".
 

I believe I've found all of the charging "parts". Is the cutout relay just above the starter switch? I found out that when cold, the generator puts out 9+ volts. Within 2-3 minutes it goes to -3 volts. I put two squirts of 3 in 1 oil in it the other day. Was that too much?
