2004 GTO Power Problem
Thank You
Thank You
My trans am was only showing 8.5 volts and it had a new battery, alternator tested good, grounds were secure, and still had low voltage but once I replaced the cables all was well and everything worked fine.
If you (Hold Mode + Set then turn the key to ON) that should get you to the secret menu to display voltage keep an eye on it and to see what voltage you are getting.
