Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello and welcome to just answer, my name is ***** ***** master tech here to help. I cannot see or hear your vehicle so I rely on your input to my questions so I can help you better. I read your notes to what you have done so far and have a few questions before we start. How old is the battery and did you do a proper battery load test on it with a carbon pyle tester? Did you also do a starter draw test on it? Did you check the cables at both ends for corrosion and clean and tight? Never assume things are good until you do those tests because if those things are happening when trying to crank there is obviously a loss of power. Please do those tests and get back with the results so we can continue.
I hear you, but lets do those basic tests first to be confident all those issues are ok before we move on.
This condition only happens when you are trying to crank the engine am I not correct? if so then it is an energy drain in the system not a short.
I'll pass this on to another that may have a different view on this good luck. just disregard ratting me as another will be along.
