Damn, Harry - if it wasn't for bad luck (w/car electronics) you wouldn't have any luck. You weren't near a Crystals were you? Maybe it's you "magnetic" personality that's F'ing your electronics. j/k
Seriously, you need a Moroso main battery cut off switch whenever you "play" with electronics. It's just alot safer than playing Russian roulette and hoping you won't get a power surge/spike. Hope it's something simple and not costly to fix..
