Default Re: Rebuilt Generator installed: Higher the RPM the more discharge

I know there are a couple of wiring diagrams out there that show the wires on the ammeter at what appears to be opposite recommendations.

But, the diagrams are looking at the ammeter from different sides...

The color diagram I posted is looking at the ammeter from the passenger compartment... so the yellow wire goes to the drivers side post and the yellow/black goes to the passenger side post (when the ammeter is mounted) - at least I'm reasonably sure that's correct - anyone else confirm?.

Since it appears your wiring is not 'stock' (per the photo of the yellow wire) - be sure you trace it all the way to and thru the terminal box to make sure nothing crosses over there.

Once you get the reading issue straighted out - you may also have to set the 'third brush' in the generator to the correct output... more on that later after the readings get right...
I tried turning on the headlights and I am at about a +5 charge. Would this mean the ammeter is wired backwards?

1. Did you polarize the generator with the engine running or not running? Needs to be not running when you do this.

2. Since you are getting current out of the generator, it's possible that the cutout switch is not working AND that the ammeter is wired backwards. If the cutout is not opening when the engine is turned off, the battery will be drained as it tries to spin the generator.

I'll check back later as I have a meeting to attend.
The engine was not running when I did it. And the car I think does charge the battery, because If I shut it off after running, it will restart with no problems. Also using the headlights doesnt seem to affect it. The only time im having trouble with it dying is if I try to start it multiple times in a row (cold start) then after a few tries the battery is toast.
