Please read Posts #12 and #18 again.Could there be something that's causing the battery to put out high voltage, or is that what the battery rating is?
So then it's normal under those circumstances?Please read Posts #12 and #18 again.
If you're sitting in the driveway, doors open engine off, key: ON playing with stuff and pulling codes the battery voltage will drop RAPIDLY - and the fuel door and trunk WILL pop open. Low battery voltage.
Well that's what's confusing: everything runs fine with it electronically, except the alarm, which hasn't worked properly since it came out of the shop. Other than that, it starts up fine, and all of the accessories work. I also don't leave anything on without the car being on...a lesson I learned by burning out a battery in another car back when I was traveling for work and using my car as an office. I don't have that problem with this car now.It's not that common. Battery voltage has to get pretty low (damn near dead) for that to happen. I've never tried it, but I'd bet you could leave the key on and run the radio for an hour before you drain the battery low enough to start popping open fuel doors.
