89 Sunbird blowing fuses
My son's has a 1989 Pontiac Sunbird 132000 miles. Last week It blew the fuse that controls the gauges(temp,gas,oil,alt and speed odometer) I put in a new fuse and it was ok for a day and then it blew again. Got under the hood and looked for a bare wire found nothing, wiggled a bunch of them around and put in a new fuse. went for 3 days and then blew again. About a month ago It blew the fuse for the dash lights. All this has happened since my son and I put in a new stereo. We used the same wiring that the old stereo had.Also when the fuse blows I get a warning light that says check gauges. It flashes on just as the fuse blows and then is gone. Anyone got any ideas where to start. Oh and we also put in new speakers. The left front one is directly over the fuse box. Think I may have nicked a wire when I screwed it back in?
