Possibility:
The wire got cut into some where after the fuse and is grounding out against the chassis.
Rip up your power wire and inspect it see if there is anything obvious...if you find something get some electrical tape and tape it up, then make sure the obstruction that punctured it before, will not puncture it again.
Did you check your fuses?
Nothing to do with the problem but:
FYI:make sure your ground is at least 12 inches or shorter!
PM me for any help.
