Nearing the final stretch with this thing finally. Lot's of rodent damage everywhere has really taken time to sort and repair. Muddling through it however. Now have operational work lamps, glow plugs, interlocks, and engine shutdowns. Gone however is the 30 second delay from fault sense to engine shutdown as that was chip controlled. In layman's terms that means if low oil pressure, engine overtemp, or elevated hydraulic termperature is sensed, there is no delay in engine shutdown and it will be immediate.
Will be incorporating my new control panel today but have one circuit yet to figure out. No point to point wiring diagram available and will find this wiring run via multimeter. I can make it work with the original card in place, but now need to go around that circuit as have all the others. This allows for an unmolested original wiring harness, (albeit several repairs). Engine starts and runs from my homebrew concoction and glow plugs cycle as they should. Same safety systems are active and engine immediately dies if any are compromised.
One Eye Wonder:
After finding yet another wire compromised and repaired:
Owner tells me the lights have not worked in the machine for many years. Rodent damage corroded the termination that supplies power to the circuit. I "scabbed" this in there temporarily going around original fuse till I can get the correct pins that go into the fuse block. It actually tucked away nicely and is readily accessible though I didn't photo the completion:
