Im doing a few minor repairs on a friends pinbot. I have everything fixed except the left jet bumper. Neither the switch or the coil work in test mode or game play. The coil fires if I ground the tab on q73
System 11 troubleshooting is not my strongest skill so I could use a little hand holding here.(The repairs I was asked to do originally were mechanical issues, I just want to see if I can fix this problem for him as well)
I confirmed continuity from both the coil and all switch wires to the connectors at board and all is good.
The lower scoring switch on that stack works.
Please advise, thanks
