Default Kicker zx1500. 1 no output.

So the this Kicker came in. Power supply tests ok
The outputs all test OK as well. The inductor is loose on the pcb. This resistor is very swollen and I'll need to replace it.
The relay is not engaging. The power supply drive is present and good.
That cap is very swollen.

With no power applied, what's the resistance from the large output inductor to the negative speaker terminal?

Do you have rail-rail oscillation or DC voltage on the large output filter inductor?

Do you have 12v across the diode next to the relay?

PapaZBill can tell you whether the diode is across the relay or not (I think it is). If it is, the relay should be engaging.

Is there audio at the speaker terminals (I assumed, not).
