Re: Amp not working, cant figure out the weak link.
That means the RCA cables are supplying the ground connection to your amp. DC current through the RCA grounds is what the diagnostics light is telling you. Originally posted by BobTheSlob So next, I pull out the RCA cables. The diagnostic light goes off, but the power light isnt on either.
Rewire the ground connection on the amp.
