Grove AMZ46NE:
Grove Amz46 no movement, shifted

Hi,
Just picked up a manlift at auction and she has a couple bugs I am working through and need some help. Hoping someone has some knowlege of these units as they are discontinued.
Unit came without working batteries so I put in a brand new fresh set. It is a electric manlift.

Basically I have no controls or movement on anything. Power to the board and controls apears to be good but I am getting 3 blinks off the controller. Code says the contractors are welded (checked all are good) or the mosfet is short circuited. I think it's the mosfet but I don't know where to start diagnosing this item.

Any help appreciated!
