In my attempts to get my 8N to charge I thought I had it whipped. But after running it for some time the battery will go dead, even though the amp. gauge shows 11 amps at an idle, and goes up to about 15amps when the engine is sped up. Here's something I noticed. When I turn the key switch to on the needle on the amp meter will jump up to +10amps, I figure this was because of the points being closed, but I finally realized that it should be -10amps, so all along I've been thinking that the generator had been charging, but it has been discharging. What I need to know is which connection do I cross to polarize the regulator?
