Hi all,
At the collision center I work at we just repainted a mint condition 73 Super beetle with only 53K orig miles. When I say this car is mint, its truly MINT! Original owner and completely unmolested since new. Full service history since 73'. Original everything in perfect condition. Its literally a little old man's car. It's his pride and joy.

Anyway, it keeps blowing fuse number 12 as soon as you turn on the signals. I'm thinking its a ground on either the front or rear signal lamps. Also when turning on the hazards it pops that fuse too.
Any ideas?

Thanks

Sorry, but it is not a ground issue. The ground is after the load (bulb, etc). If the fuse is blown than the current is bypassing the bulbs on the B+ battery voltage side of the circuit. The B+ wire is touching the body somewhere. Hence the current has found a shorter path to ground. (a short circuit). Visually inspect the wiring coming from the turn signal switch to make sure there is no chaffing of the insulation, etc. If not there, follow the wiring to the bulb sockets and inspect them. Since the hazard flashers also blow the fuse, than I would suspect the bulb wiring in the vehicle is chaffed somewhere since the hazard circuit is different than the turn signals. What they have in common is the actual bulbs for each corner wiring.
 
Also, when painted I assume that that all the lights, lens and other body components where removed. I would check the installation of the light assemblies, front and rear to see if someone pinched a wire during re installation.
