Question about 1987 GMC V1500
I have recently installed an engine and Transmission, for some reason I can't seem to get the new starter to crank, it works on the bench test, The battery is fully charged, Im wondering if Iv'e got a wire crossed somewhere. I got a haynes and a chiltons repair manual but it doesn't show any thing about crossed wires in the starting system. So, if someone could point me in the right direction for a good schematic for the ignition system, that would be great..
I own a shop, and think this; If you have a Chilton's Repair Manual, you can go to the back of the book, and locate the typical wiring diagram for most all GM vehicles. They are basically the same on all of them. I know the Haynes Manual has these in the back pages, so look there first. I have a feeling you have not got the neutral safety switch wired up. There should be a yellow wire that comes from the ignition switch that goes to this switch. The switch is located under the dash near the clutch linkage on a straight drive, and on the transmission for an automatic. There should be a purple wire that comes from this switch that goes to the starter solenoid. It should have power on it "only" when the ignition switch is turned to the start position, and the neutral safety/clutch start switch is activated. This switch may be out of adjustment, and not sending any power to the starter solenoid. This wire should hook on the terminal that is closest to the engine block. The other wire will have power on it all the time when the ignition switch is in the on position, and should hook to the (hold in winding) on the other side of the solenoid. You may be loosing power, or not have any power on the purple wire that activates the (pull in winding that is closest
