Hello,
I have a power/control board for a John Bean tire balancer made my Snap On. the numbers on the board are:
PWB EAP0167G30A
ASSY EAP0167G31A
I bought this unit after watching it in operation yet when I brought it home and plugged it into 120V, it was completely dead. The switch and fuse were good so I removed the board from the machine for further analysis. When I did, VR3 fell from inside the cover. I resoldered this resistor but it still will not power up. Further inspection showed that VR2 was about to break off as well, so I removed it and resoldered it as well, but still nothing. The jumper wire was already on there and I believe this is evidence it has already been repaired once.
Any ideas where should I start checking first?
