Swap the amps to isolate the issue!

If you really really have wired then identically, then one of the modules must be faulty, so I can't really see what your alternative is (and that's why I powered then up before assembly)

I did power them up and I got all the LED lights on both. As far as I can tell, that is all you can do, without building them out. Does anyone know if the led lights provide and diagnostics?


Guess its time to break them down.

Looks like I either got a bad module or I did something Though I cannot see how I could have caused anything. So I know both power supplies and one amp work.

As far as I know, no. I understand they are there just to provide a stable voltage drop. They are not driven by any sort of logic circuit.

almost, note that while they are not indicators as Julf says, they do provide indication of whether there is power and if it is in standby.

No LEDs on= no power
some LEDs on = standby (forget how many)
all LEDs on = ON
