Now that you've got the voltage regulator running its own show, is there still a reason to supply voltage to the old "Out of a job" computer? Asking for a friend with an 88 D100 who will need to know!
:lol:
I have tried running with the computer unplugged and it still starts and runs now the way I have it wired.
There is one main power feed that unplugs at the Battery that powers everything in the cab: key start, idiot dash lights, head lights, turn signals and fan motor.
With that main feed plug unplugged that all goes away.
Going to try to set it up now with the main feed plugged in, and the old computer unplugged. Believe that is going to work to get it road worthy.
Really would like to rewire the whole truck to Old School from scratch. But for now just want to get it up and running reliable.
