Finally got to test the new wiring. Lights all work, engine starts, runs well. Richard is in the process of starting work under the hood. A new alternator is going in (105 amp for a 91 c2500) and the old voltage regulator is going away. Burned wires need to be pulled and it needs a serious cleaning.
But i'll let him tell you about that because as I have stated, it's far more work than I am able to do. I have gained a new respect for those here who have accomplished this type of project and also for my friend Richard who has worked tirelessly to help me get this far. Many thanks to all.
