Happy new year.
My '98 Lumina was clicking when trying to start the last couple days. Radio time would reset to 1am, so I was completely losing power. Figured bad battery connection.
Dug into the battery, discon both cables from terminals. Clean with wire brush, re-attach. Get in car, have zero power anywhere. So then I discon the negative cable and check voltage from neg battery post to frame and it shows 11.5 volts. From positive post (that cable still connected) to frame, I have 1.4 volts. There's 12.9 volts direct across the two battery posts.
Assumed that I should have 0 volts from either terminal to the frame with neg cable removed from battery. Am I wrong? I do fine with the old 60's hotrods but I get lost quickly on the newer stuff, so my troubleshooting technique or assumptions might be totally off base.
I've inspected both main battery cables, they look fine. 0 ohm resistance end to end. Haven't touched anything else electrical in my efforts so far. I did detach that fusebox near the battery so I could move it out of the way to remove the windshield washer reservoir to get to the battery, but that's it.
