pretty straight forward, a few months back my battery died when it started getting very cold (thought it was weather related). After a charge and me pulling out the amp and head unit the battery was back to normal. It is finally warm out today and I thought I would diagnose the problem. Where would i start to find out what might be pulling some voltage when the car is completely off. I have a digital and analog DMM. I am guessing that the headunit (dead head) can't even pull power with the car off.
I guess the first step would be to hook the nine.5 back up and check to see if there is any voltage at the remote wire hookup with the car off?
thanks for any help guys.
