4.3 gm diesel schematics

Anybody out there have schematics for a 4.3? I have no glow plug light or operation and am looking for a schematic. Tried google images without luck and even signed up as an AutoZone member to use their repair guides but could only find 5.7 and 6.2 schematics. I did find some repair guides on sleezbay but they want too much $. Im going to trouble shoot the system by basics for now and figure out my problem but would like to know exactly what im looking at. If I find schematics ill post them up.

I will look and see what I have, seems like 83 is the newest full set of Cadillac manuals I have. Seems like I read that 85 was kinda its own animal. I may have a 'motor' manual that covers 85. Will try and look around later.

Cool. I think ive narrowed it down to the controller. Its basically the same controller as my 6.2 but its $180.00 for a new one. Ive got a spare so im going to wire it in quick and see if that's the problem.

Nothing on the 4.3 in the 83 Cad manual, I think the 4.3 was not in the cad till 85. Didnt get a chance to look at other manuals but it does seem like it would be similar to a 6.2 so that seems like a good plan.
