My battery keeps dying just sitting in the garage. I used my test light and it shows that my “sunroof” and my “cigarette lighter fuse” was on. How can I fix this?
Re: My car battery dies just sitting in the garage
How did you determine the parasitic amp draw? Do you have any aftermarket circuits installed? You will need to trace out the circuit and find out what might be on. Bad aftermarket wiring is usually the source of this.
A good way to determine the problem is to use a good meter (must be accurate to low mV) and check the voltage drop across all the fuses. Use one of these charts to determine amp draw. There are good youtube videos as well.
