Crown SP4000 SERIES:
Won't raise

The lift raised once for me (I raised it just enough to get cart of the floor), another tech told me that it was in for not raising, went back to it and couldn't get it to raise. POT2 is good and getting proper voltage. M3 is not getting voltage, so I know it somewhere in between access 4 and access 2, just hoping maybe someone could steer me towards a "quicker" fix. Thanks

All signs pointed to Can H. We have hydrogen fuel cells, so we swapped it out and the problem seems to be gone.

The quicket fix is really just to trace backwards from the motor to see where you loose voltage. Possibly could be a module issue but I dont know the history of the lift to say for sure.
