Lots of electrical problems start with grounds. Congrats on the fix.

No start problem
This morning the wife's 2000 C5 would not start. Basically it will not turn over. You can hear the solenoid click but that is it. I check the battery and it was 12.5 volts unloaded. I went ahead and put the charger on it unitil it was up to around 13. 8 Volts. Same problem. Tried jump starting it with my F250. Same problem. I looked at all the connections from the battery to the starter and could not find anything wrong. So I came to the conclusion that the starter was bad.
Installed new starter this afternoon SAME PROBLEM
It still just clicks. Ideas ? I put the battery on charge tonight and will have it tested tomorrow.

Starter solenoid engages (clicks). This tells me the signal is getting to the starter it just does not have proper power to turn the starter over.
I think this means bad battery or connection issues with the power wiring. I'm going to take the battery and have it tested. I put a full charge on it last night. If good then I guess I start looking at all the power wiring and connections to the starter and engine gnds.

Car is fixed. Battery checked out okay. Removed an cleaned GND at engine block.
Removed both molded cable ends + and - at battery and remade connections with new battery terminals.
You can't see the copper wire inside of these unless you remove the molded part. Both had corrosion on and in them. Cleaned battery terminals.
Car now starts. Guess I should not have assumed and took a closer look at the wiring and voltage drops. Oh well car has 130K on it so a new starter did not hurt anything.
AC compressor has gone out so guess what I get to do next.
