2007 Focus ZX4 - Battery Drain From Radio
I've been doing various repairs on my 2007 Focus ZX4, so it hasn't been driven lately. I found out that the battery goes dead if the car isn't started for about seven days or more.
I tracked down the problem and it's related to the radio. I removed the fuse for the radio and the battery stays charged. I'm able to start the car after it's been sitting for a month or two.
I guess this isn't a problem if the car is driven on a regular basis, but I'm wondering why the radio is draining the battery dead within a week? Any fix for this problem, or maybe the radio needs to be repaired/replaced? Thanks...
