I guess i just assumed it was externally regulated because one was there and use to be hooked up, and thought a two post alt. meant external. I guess i should have mentioned the motor is a 350 out of a mid 80s truck.
I tried a few variation of which wire goes where and then turned the truck on. The only thing i could get a charge with is the way its set up now.
So the 1# or field post runs to a wire that needs power, and the second post to a indicator light( from what i gather) then a wire from back post to battery?

I'l have to look into wiring it to the coil cause believe it or not i'm running out of room for new toggle switches!I guess i only have three but that's still probably more than most people haha.

I didnt think i would need to unplug the battery for fuses but if that's the case il wire it up to the ignition switch. I just used the horn relay because it was convenient, and wouldnt have to splice the current wiring together, or go out and buy a longer wire. By the way what gauge wiring should i be running from the horn relay to the fuse block or horn relay to ignition switch then fuse block?
