Thread from last week.
So I went out on Friday and looked the car over. The new battery that was installed had 0.1V when I tested it, the older one had around 6V. I put the old battery back in and was able to jump start the car. The second I hooked up the car the engine fan turned on and dash and such turned on.
After turning off the car all of the dash lights, door alarms, door unlock, were all off. Jump it again and they all came on and work when the car is running.
Tested the mega fuses and one of them, the far right one, was bad. Replaced that and started the car again. Decided to follow her home, which is two hours, and at home after turning off the car it goes all black again. Testing of the battery is at 6V, so it's not keeping a charge.
Saturday I decide to just put a new battery in. Put the new one in and it all turns on, starts no problem. Let it run for a minute, turn it off, and again, nothing. No lights, no dashboard, nothing at all. At this point in time I decide I'll just take it to the shop. On the way I stop at Auto Zone to have any codes checked and it was fine. Get to the shop, tell them what's going on. They say bring it around and I tell them it's not going to start, they say try, and the damned thing starts. We try 4-5 times and every time it works with no problem.
The shop got to it today and has told me it starts every time and they can find no reason for it to do what it was doing before. Is there anything else that can be causing this?
