Hi Michael,
The easiest way to track down a short like this is to take a 12 volt auto
lamp, inserted into an old socket and use wire from the socket with a couple
of simple alligator clips to allow you to clip the leads to the two fuse
clips for the fuse that is blowing. An ordinary tail lamp is fine. Or just
buy a standard 12 volt test lamp and attach it across the fuse. The lamp
should be lit brightly. It will stay bright until you locate the short.
Now just start unhooking each item powered by that fuse. Also wiggle the
harness in all areas especially where it passes through the body or appears
frayed. It can be as simple as a bad socket for a tail lamp, a short to
ground where the insulation is worn by age and rubbing against the chassis,
but this is the easiest and safest way to troubleshoot a problem like yours.
Good luck and let me know if my description wasn't clear enough. This
should be an easy fix.

Subject: Blowing 35A Fuse
Listers,
Today I was driving and noticed that my left turn signal was not working.
Quickly relaized that right turn and brakes were not working either. Popped
the bonnet and sure enough -- lower fuse was blown. Replaced, turned on
ignition, blew again. What is the correct way to troublshoot the cause of
this without destroying a fistfull of fuses? I imagine that I would use an
ohm meter but am not sure exactly how or where to begin. Does anyone have
any tips on the most logical way to proceed or any shortcuts to the most
likely culprit? The harness has less than
2,000 miles on it.
Thanks,
--Michael
