I had mosfets fail before. They failed shorted. If yours are shorted then a precharge resistor would burn out trying to carry all the amps the motor is drawing.

You will have to disconnect each mosfet to find out if any are still good. Sometimes they don't look bad but are.

They could have been damaged from the heat of the soldering gun when first installed.
