Still having shutdowns,almost daily now.
Main fault,Brake fault.

Replaced every pmi module,relay,brake switch, and what not.

I was running it on inspection from the MR today and about every 5 or 6 starts( I was running it a couple of feet at a time),the brake would pick,the motor would turn maybe slightly,the stop,then the brake would drop.When I press the down,or up button again,it would run.
No faults would show.
