Hi, let my ex-husband install an amplifier and speaker box into my 2002 Ford Escort ZX2. It's not really that big of a deal but now my tail lights and dash lights will not turn on. We found the fuse and replaced it, but the minute we turned the headlights on, the fuse popped again. I know there's probably a short somewhere, but am not real sure where to start. Please help me if you can. Thank you ion advance!
Sounds, no pun intended, to me like possibly a circuit for those systems has possibly been either overloaded by hooking up one of your new pieces into it, or the person who installed it may have inadvertently pierced a wire and grounded it, thus shorting it out.
