Pulled all outputs, still pulsing. Must be a protection circuit issue in supply.
The gate signal looked fine in the power supply prior to populating the 3205's, maybe one of the transistors is leaky. I have seen that before, signal looks fine under no load. Once a fet is populated it goes bad.

Looking at the other mods (near U3), I'd suspect this is factory. I looked at another board with exactly the same part number (PAS344-01) and it was significantly different so this may have been from a prototype batch of boards. They generally change the board number when they modify production boards.
Well pulled all outputs, rectifiers and still pulsing in protect mode. Removed 2 fets per side on each power supply thinking it was a loading problem, no change. Removed all the fets from one supply and left the other partially populated, still in protect. Removed all Power supply fets and comes out of protect. This tells me it is secondary supply issues?
Confused, yes I am.
