I have a '91 Integra LS, stock, with a brand new battery. Here's the problem: after sittting for several hours, the battery will be dead. It doesn't seem to be the alternator, because after driving for awhile, the car will start right up. It only seems to happen when it has sat for several hours. Something seems to be draining the battery when the car is off.

Here's a hint: I just bought this car, and it didn't seem to have any electrical issues when I bought it. A couple days after I bought it I replaced the thermostat. I disconnected the starter ground wire on the thermostat housing. I hooked it back up the same way it was, but I can't think of anything else that could be causing it.

Any ideas on where to start?

check the fuse box under the hood, look for the battery fuse.

 

Fuses are all good.

 

take off your positive wire from battery. touch it back again, see if you can hear or see anything kicking on when you do so...maybe a short somewhere..

touch the terminal, then remove it, repeat..
