Only parts out are the output fets.
Is it possible its parts on the driver power supply board.
Everything was fine till it started pulling amps from the shorted output fet.
It still was showing green light even during the high current, did have 2ohm and 7.5 v fuse in at the time

When you first apply remote voltage, do you see a pulse of DC voltage on the output filter inductors BEFORE the relay?
The inductor is the heavy gauge wire with around 10 or so turns?
If so yes.
Remote connected power supply goes to about 7 amps then back to 0, and the inductor goes up to about -19 volts and then slowly goes down.

Confirm that there are no solder bridges between the pads for any of the output FETs. Clean with acetone, top and bottom.
Do the same for the driver board header.

Is it me or does it look like there are solder bridges between the pins on the TL594 chip?
