USAmps 50x REV 02 remote turn on blown

Cr@sh · 12th June 2011, 02:05 AM

Well as the title states, I used a battery charger to power up the 50x whilst working in my garage. I didn't check that it had been set to 16v. Although this isn't a problem for the B+ input the remote can be no higher then 12v (maybe 14.4 as some vehicles charge that high) anyway it smoked two resisters.

I removed them and of course there burned so I can't determine which ones to replace with. I looked everywhere I know of for schematics and found nothing. One shows R335 and the other R235 on the board. I am new to learning electronics and I will assume that those numbers aren't actually the resistance in ohms. How can find out which ones to replace with? They were brown

thanks in advance, also I searched here as well. I thought maybe there'd be a sticky on how to find out.

Contact US Amps to see if they can give you the value of the resistors.

This was pre REAudio, however you may be right as they may have records of it. Thanks Perry
