450 diesel wiring help

Looking for a little help with the wiring on my 450 diesel. I recently just bought a new wiring harnes from brillman company. After installing the harnes and putting a new regulator on the tractor is up and running great. Problem I have is that ammeter while tractor is running barley runs on the charge side. (More like zero) When lights come on it moves a little more into the charge side and when I hit the start button it pegs the gauge to the charge side but the last few times I go to start the tractor the battery is dead. I have checked and rechecked all my connections and wires according to the directions given to me from Brillman. (Tractor is a positive ground) Just curious if anyone could point me in the right direction. Also If someone could tell me what service manual to buy that would have the wiring diagram in it. Recently bought the I&t version and dosent not have a diagram in it. Any help would be much appreciated!
 
You might want to call Brillman and ask him.
He is a wealth of knowledge and will walk you thru to find your problem

Something is definitely wrong if the amp meter pegs when the starter is energized. That it moves to the charge side sounds like the gauge is wired backward, simply reverse the connections to correct that, but still it should not peg when cranking.

The running amp reading, and the discharged battery indicate it is not charging properly. Did you polarize the generator?

You can search under images and get the wiring diagram. I didn't see the diesel diagram, but the gas with positive ground and generator should be close enough to get the basics.
