I just bought a 1993 mustang gt about a month ago. It's been a good car but I came across a problem today. Here's how It started. I ordered an amp so I decided to go ahead and wire it before it got here, that way I just plug it in and go. I slide the power wire through the wire harness. The hole in the firewall with most of the wires. I'm thinking maybe a wire got ripped or something. But I didn't use any force to fit that power wire in. The power wire for the amp touched a screw but no fuse or anything got blown. I started it up today drove it down the road parked it for 5 minutes it and had to get jumped off. within 10 minutes the head lights would flash because the battery was so low. Right now I have to jump it off to get started and within a minute the headlights start to blink. Would could be the problem here? I'm getting the alternator tested tomorrow.
