hey, i got my engine last week and have been having electrical problems ever since. my taillights work sometimes, and the fuse for it blows twice a day. the cd player doesnt work, even the gauge lights dont work. my mechanic said something about a check light relay. others say its a ground.....? any input please, specifics welcome!!!

If you're blowing a fuse then you have a short in that circuit some where. Your check light relay I believe is located next to the fuse panel under your dash (You have to remove the lower dash panels to remove the relays).
