Slam tilt switch is stuck closed

<< < (3/3)

cataylox:
According to the schematics on page 3-13 both slam switches are wired in parallel and connected to SW21. We need to figure out which slam switch is causing the problem.


There is a connector for the coin door J4. If you pull this connector instead of J3 on the controller board does the slam switch still register as closed?


If yes its either the Cabinet slam or the cabinet wiring.


If no, then the coin door switch is the culprit.


Loosen the screws holding the switch to either the door or the cabinet and wiggle the entire assembly to see if there is a short in the assembly and the Green with black stripe wire. This can be done while in the switch test to see if you get any indication that the switch is working.

Thanks guys, I got to the bottom of it.  It was the cabinet switch.  I had checked it several times but hadn't noticed the second contact underneath because it's kind thin and covered by the top one - I thought the second contact was the bracket it was mounted on.  So it was just that it was stuck closed because it was bent a little.  Stupid, I know. 

PPS:
glad it's sorted out!
