Wiring issues in a K3500 turbo diesel

[Hammack1975]

Guys could anyone lead me to wiring diagrams of the engine electrical on a 97 K3500 with the 6.5 turbo diesel and a manual trans? Specifically the ignition system. I have had a rat get in my engine compartment and eaten a bunch of wires in spots. I found a few burnt wires going down to the starter and I can’t now get the starter to turn over. All fuses hot, but not getting power to the starter solenoid when cranking. Thanks

That'll be in the GM service manual. Some of them are downloadable from this web site.

First Guess: Purple (fades to pink over time) wire to starter motor "S" terminal is open.

Second Guess: That wire is powered by a starter relay on the driver's side inner fender. Worth making sure that the relay is powered, and working properly.
