I have a 1990ford foxbody. Had stereo put in now it runs my battery down if car sits for 2 days.installed new battery no help. Something on that fuse line is killing battery.

Asked by GuruH8ZG3 Jul 29, 2019 at 11:16 PM about the 1990 Ford Mustang GT Hatchback RWD

Question type: Maintenance & Repair

1 Answer

Most stereos have two hot wires. The main power wire is switched when the key is off. The other one is just for the clock. If you got it wrong this might be the problem. Measure the amp draw when the key is off with the stereo fuse in and out.
