Another 3 hours of work done. Getting closer...
Got wiring done (I have deleted the stupid GPC and harness on the 85 engine), adjusted clutch, put in starter (the big heavy bastard for now), and some other little things.
I can also confirm that the fuel solenoid will click with 7v in the batteries.
I need a coolant circuit diagram for an 83 with no ac ("high output" heater).
What would cause the glow plug light to constantly be on? From what I can tell the wire that is supposed to turn that light on isn't even hooked up right now, and I know the glow plug solenoid isn't being triggered since that wire isn't hooked up and I checked to make sure there was no voltage on the GP side of the solenoid.
