i have a cforce1000 where the eps dont work
initially we had the 40amp fuse blow and figured out the controller had a blown mosfet, sent it off to be repaired.
when we got it back it works for 1 min until we get the fault code 32. 3 long 2short flashes
the fuse no longer blows.
the eps aids in one direction but not the other way
we have inspected the harness and plugs and no sign of damage or corrosion.

Likely the unit itself. Not sure how to test it though.
