  What is the best way to find a short circuit?

  Eyeball the insulation at any point where it can rub on the frame and wiggle the harness to see if you can recreate the problem. Buy a reset-able circuit breaker so you don't have to buy a bushel basket of fuses. See my response in brighter taillights topic

finding a short
you could try also to remove the battery ground cable and install a trouble light
from battery terminal to grd
if it LIGHTS,[ you have a draw, ] you can then start wiggle the wire connections,
I would look for frayed wiring
HOW OLD is YOUR WIRING ?
what is on when you blow the fuse ?
it would help if we knew what model and year car you have
do you have a repair manual ? for your car ? you would be surprised what is in there,
hope this helps 1937 Ragtopman

  At the suggestion of TOMO, I bought a breaker fuse to save having to constantly replace while I source my short. Works like a charm.

  How about info on these breakers - I didn't even know they existed, and I saw no info on these in the 'brighter taillights' post referenced. Where'd you get it? Manufacturer? Amp ratings available? Etc.

  I found this one on Amazon, it was around $3. Mfg. by CEC Industries. They had a lot of different AMP choices. Under 20A Type 2 Circuit Breaker. There were some options you could wire in. I liked this style because it basically plugs in the old glass fuse spot.
