How to track down an intermittent short?
I have a 1986 Corvette, 195k miles. Runs great. Recently I've had problems with blowing the 15A fuse that carries the load for the turn signal and backup lights. Sometimes I can go a month or two with no problems, other times I'll blow two fuses in a week.
What's the best way to track down this intermittent short that I have?
It's definitely not cancelling, as the fuses are blowing. I'll check for moisture, but there's nothing obvious from an cursory view.

intermittent..........don't envy you.
[EDIT
>normally,
any issues with turn signal prindler physically not self cancelling? hear any scraping or chaffing under the steering wheel? springs pop off and plastic breaks causing shorts.] any moisture in a rear lens? socket and wires behind it good? check the reverse detent switch? only clues i know of to narrow it down. other than that. well.........you're chasing.

By looking at the wires themselves to see if any are bare are close to any metal frame pieces. If any are found replace them or tape them up good. You may get lucky and fix it by just moving wires around.

start at the taillights and work your way to the front checking the wire looms
