Was wondering how a thumper bumper would act with a bad switch. My middle thumper bumper will not work when the plunger is hit. I ran self test and the switch isnt working. However now when my slingshot solenoids fire, the middle pop bumper will fire.

Do I just have a broken switch or a grounding problem or both?

Thank you!

Broke more

Now it seems that I have broken another thumper bumper switch. When I run the switch self test, switch 38 chimes and sometimes 40. Did I take out the snubbers or are both switches bad?

Solenoid test runs fine. Neither left or center thumper bumper work now :(
 
Fixed broke

Ok so I decided to change the cap on the switch at lunch. Seemed to work. Came back from work and changed the cap on the left thumper bumper. It works now Too. I started playing the machine and the middle thumper bumper stopped working again.

I resoldered the cap and it worked 3 times. Stopped working. I turned off the machine and it worked 3 times again and stopped.

Now the middle thumper bumper isn't working at all again. the left is working fine. Should I just replace the switch diode and cap?

Anybody? :)

If it's doing kooky stuff like you described, I would definitely suspect one of those caps....
 
thanks me too. The switches do have caps on them.

thanks again for your help :)
