Put the new battery in on Tuesday and yesterday it was dead. I checked the grounds first and everything was good but just to make sure I unscrewed and cleaned both of them. Then I checked the thinks that you mentioned and everything checked out fine. I hooked the battery to my bench charger and once it was finished I plugged it back into the car. I checked the volts and when the car is off the battery was reading 12.90 volts at the terminal. I also checked the volts using the positive terminal and both grounds, the negative terminal and each fuse in the power dist. Box, and the negative terminal to the positive cable on the alternator. All came back between 12.8 - 12.9.
I went to start the car and it just clicked so I checked the battery again and it had dropped to under 8 volts. Once I jumped the car the battery was reading 16 volts so I checked all the same things and all came back between 15.9 and 16.
I left the car run for a little over an hour then turned it off. Went back out this morning and the battery is dead again.
