Ok so last night my friend installed a cd player in my car and there was alot of wires left over that were exposed.so im driving home and notice my taillights/interior lights are off. so i pull over and look into it and notice the fuse is blown, drive to a gas station and put in new fuses and blows them as soon as i turn the switch. call my friend he said its a loose wire shorting em out. i tape them all up and pop in a new fuse, ok it works. get about half way home and noticed everyhting is off again, pull into a parking lot and go to change the fuse but the fuse is still good. so every unused wire is taped up and not exposed, fuse is good, bulbs are good. any idea's???
