Hi all,
received this amp in protection, previous tech removed all psu fets. I tested them, didnt find any shorted. On the outputs the low side drive seems fine but the high side drive rides along ground and no output the drains.
high side fet:
G - ground
D - positive rail
S - ground
low side fet:
G - negative rail
D - ground
S - negative rail

Hi Perry, there are 2 good drive signals from the driver board. Could D10 and D12 possibly cause this issue?
Unless those are shorted, I don't think that they could be a problem.
Have you followed the signal through the drive circuit to see where it's lost?
