new harness problems
I am currently putting in a new American Autowire update harness and I have finished the front light and engine harness and have the dash kit in place. My problem is when I turn my headlight switch on, I have 11.85-12 volts of power to my light connector, but the bulb will not turn on. Neither will the grill park lamps. Also, when I try to turn the key to spin the motor, I get nothing. Not even a click. I have a Powermaster Mini Starter. I know it works because I did the old screwdriver across posts trick. Whats going on? When I test power at alternator I get power at all connections.
If we still cant figure out by noon friday I'll call AAW. |

Did you put the fuses in?

Re: new harness problems
Sounds like you did put the fuses in if you have power at the light connector. The only other thing you need would be a good ground to complete the circuit.

Or do you mean the engine to frame, engine to body and body to frame grounds? Should I have a radiator core to frame ground?

Battery to core support Core support to frame Chassis to engine Box to frame For example on th lighting harnesses for 73-up trucks the headlight ground is on both sides of the core support-the RH one share a core support ground along with the battery and a 10ga ground to frame as well. |
Re: new harness problems
Found my issues: I added a radiator to frame ground and engine to frame ground along with a new bulb and works good. I was able to turn the motor by bridging the neutral safety switch connectors.

Re: new harness problems
Companies like AAW and Painless often go by simple GM factory schematics-often they neglect multiple revisions and/or changes to production prints which in the end give customers install problems unknowingly.
