Hey guys, I have a 1994 chevy 1500 z71 5.7l, And I'm pretty sure I have a wiring issue, a bad ground or a short somewhere. When I turn on the truck, The battery meter will be at about 12-14volts. When I turn on my headlights, It will drop to about 10. Whenever I try to roll my windows down (power windows) It'll drop about 2-3volts the whole time. Having my AC on will also but the battery down to 9volts. Whenever I put it in gear, It drops to about 9-10. Whenever it drops really low, my radio will keep turning off/on and my windshield wipers will keep going. I thought it might have been the battery, So I bought a new one, And it still dose it. I had Autozone check my alternator and they said it was good. They checked The ground cable and positive cable coming from the battery and said they both were in good condition. So I'm completely lost, Could anyone try to help please?
