I'm thinking my problem with my car with my battery dieng way to quick is a ground I remeber when I took out the alarm in my car it had a ground now was that ground for thee wiring harness? I'm not sure if there's a ground forthat. I used a multimeter check the battery it reads 12.45 when off, when it's on it reads 13.85 it jumps around a little but yea so I no it's not the alternator. If it's a ground how do I make a new one for the harness??
