[QUOTE="Deiimos, post: 8746871, member: 682903"] Yeah swap the fuse with a new one and see what happens, I’ve seen fuses that look reasonably okay not work, and if it looks questionable, it might just be. Having a cheap volt meter helps troubleshooting, even a Harbor Freight cheapie would be better than nothing for quick voltage / resistance tests. I’m trying to understand how shorting the main power wire to ground would fry the amp. Seems you had a small wire connected to the power terminal and would insert it into the remote terminal to turn it on? I did amp repair for some years, did that all the time for testing (I don't recall if I ever shorted to ground, but probably) and as long as she didn’t wire the amp backwards entirely, it shouldn’t hurt anything shorting the "power wire" to the ground wire, other than possibly damaging fuse at battery. Now if you shorted a speaker terminal to B+, or B+ to RCA shields, that’s a different story and can hurt amps. I guess I’m just trying to understand exactly what happened. At any rate, hope its just the fuse. [/QUOTE]
