I have a 1990 ford tbird and I have a fuse that's grounded out number12 fuse 15 amp fuse,, but the promblem is there's a total of 17 items running off this one fuse , that makes it almost impossible
Hook up a ohm meter to the load side of the fuse and the other end to the ground, I use the continuity beeper on mine, and start disconnecting components that are on that circuit until it stops beeping or the needle shows open circuit, hopefully it is just one problem. Make sure someone didn't put a screw through a wiring harness.
