Need in Depth Technical Help for my charging syste

Hey guys.
My generator wasnt charging my system. It was determined through the help of the troubleshooting guide from BobM (I beieve he is the one who published it), to be a faulty generator. I took her apart, cleaned her all up, cleaned the comm, and all the terminations. She works now, but I am worried.

First my system is a 3 brush, I believe not an internally grounded generator. It is a 300U. There is a 3 terminal, (actualyl 4 counting the terminal on the back of the regulator) regulator, and the light switch has a resistor in it. Now when I turn the light switch to the first position, the Headlights come on dim and the resistor on the switch gets hot. When in the seocnd position, the headlights opeerate normally.

Now besides that, when i start the tractor, the ammeter shows a charge of appx 20amps. The battery voltage has been anywhere from 7.5 to 8 volts. This bothered me, as I would imagine anything over 7.0 volts is harmful long term to the bttery. I tried adjusting the regulator, but I dont know what I'm doing, so I decided to get some imput before I touch it.

From my understanding the generator is either on or off, the regulator is just some relays and does not actually regulate the field current, it switches it on or off. Is peaks of 8volts normal? How do I properly adjust the 2 adjustment screws in the regulator. I understand alot of electronics, but I'm out of my element here. I have replaced the wire harnass with one I made, triple checked all the wires when I was troubleshooting the generator.

I am happy I got the generator to work!! I'm just concerned with the system working properly now. Charging a battery at 20amps, when it is already fully charged from my float charger, for a long time can boil the water right out of it and warp the plates.

I thought about putting an alternator on it, but thats alot of work between the bracket, the reduced pulley installation, the wiring.

I actually have a float charger I keep on the battery when not in use to keep it maintained. If all else fails, I wouldnt be against just having the generator on when the lights are on. Without the lights on the battery will run the tractor for far longer then I'll every use it continuously.

I hope some of you guys can give me some detailed regulator adjustment instructions or advise on what to do.

I really do appreciate all of your guy's help. I've been on some other tractor forums, and you guys are by far the nicest people.
