GMC Troubleshooting Questions? Ask a Mechanic for Answers
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
What is the battery voltage with the headlights on?
What fuse did you remove and why?
With the key in the run position is the theft light off?
With the key held in the start position are there 2 pins at the removed starter relay, under the hood, powered?
When do you believe you can check this?
Check them all.
You can reply tomorrow. Unless you would like an answer now which would just be me posting a wire diagram showing the circuit that I am walking you through the tests from.
I am on vacation so just reply when its convenient to you and I will respond when online.
Thanks, ***** ***** key held in the start position install the relay, does it click in your finger tips when installed and removed?
With the key held in the start position what is the voltage on the 2 wires to the starter?
Clicking starter solenoid means the starter is bad, engine is not able to spin, poor connections at the starter or battery, weak battery.
Thanks for using Just Answer, and rating me so I am compensated, Chris
