  • SS Chassis problem

    Ok I have a chassis that's being a real pain in the butt. One day just decided it doesn't wanna work right anymore. Tried a known good omega tek board, contacts are good, we've checked over all the wiring looking for loose/burned connections. Everything looks good except the machine doesn't cycle. Sweep and table can be ran through the contacts. When you turn the machine on the light turns on but nothing else. The machine runs fine with a different chassis. What should I try changing?

    M1 would be a good place to start.

      do 1st/2nd ball lights work? Will sweep table run through Sweep/Table Cams? If not check fuses, purple wire from fuse to C2A plug. Any C2A Pin that might have recessed in hole. Make sure coil wires for Sweep Contactors are connected. If Sweep/Table will run by manually activating contactors, High Voltage is fine, you have a Low Voltage Control issue. also if you dont use Instructomat/Shadow Bowling, Remove grey wire from T2, to rule that out.

        If you can run the sweep thru the sweep run switch (on the mechanics control box) but not the SA…Most likely you are stuck in shadow. However, I doubt this to be the case since another chassis works fine. Most instructomat problems are on the machine side.

        As mentioned check your fuses…especially the F1. If blown…at least one of your power diodes is bad. If not blown, do a continuity check on the F1 socket with the fuse in it.
