why does my fuse keep blowing?
i hooked up an amp and sub on my fc and it was running really good. i then tried to ground everything on the car ie alternator, bklock, tranny, leading coil....etc..and for a while it was good. then i pulled the aftermarket cd player out and bolted it to the stock mount of the car and after that, every single fuse i put in starts blowing up....now i checked the positive, ground and remote wires and none of them are broken....any one know why this is happening? do i need a bigger fuse?

ya i disconnected the radio (took it out) and taped up 2 wires that were exposed, put in fuse , blew instantly, so i dont think its the wires in the radio..
I will follow the wires from battery for sure..
I thought it was a wire inside of the car, have not even took a gander under the hood hopefully i find the wire...

Depending on what wires were exposed and how long you may have fried somethin in the radio. but tracking down electrical gremlins is a pain and time consuming, but easy to fix... one of the reasons why it costs some dough to get it figured out. Good luck with it.

You simply look in the FSM to see what circuits are on the fuse, and check each one.
The other end of fixing shorts is that 95% of the time it is because of some recent work done improperly on the car. That shortens (pardon the pun) tracing down the issue even further.

Then I have no idea why it took me so long on my previous vehicle considering I didn't do any modifcation to where the short and melted wires took place and I do know what I'm doing. Although I isolated the circut on which it occured I still had no idea that the problem was located in the hatch section of the car, hidden in the frame of the hatch. Only after eliminating every other easy to get to location of the car, checking and eliminating the superficial fused wires did I end up looking towards the hatch. I imagine that the wiring on these cars would be under the same physical properties since the FC3S is older than that car.
depending on how the wires of those circuits are run it can take upwards of an hour or more depending on hardware being removed to inspect the wires. I imagine if you had help in that portion of the tear down that it wouldn't take as long.

the fuse that blows is the one ON the amp...everything else works fine, radio, speakers,....only the amp's fuse blows...and the positive cable is not grounded anywhere else
(its an aftermarket amp that hooks up to my sub)

did you check your speaker wires at the amp with a multi-meter to confirm that they do not have continuity to ground??? I'd do that before getting a new amp, because it will blow out the new amp as well
