We've got a Pinnacle crane. Picked it up non-working. Finding out that everything works, except the claw itself doesn't close. P1 connector on the board pin 14 (claw 36v +) and pin 6 (claw 36v -) are metering practically nothing. Pin 14 metered to ground reference is also zero. We've got 36 volts coming off of the transformer. Fuse F3 is good. I'm going to troubleshoot the PCB tomorrow night. Seems like a board issue, but just curious if anyone has had this issue before and found a component gone bad? Thanks
