I have an intermittent right flipper problem which I need to get resolved this week as I am having a tournament on 4/25.
Most of the time when I press the right cabinet flipper button, neither right flipper is actuated. Once in a while, both will fire.
During coil testing if I have the left cabinet flipper button depressed, both will fire all the time. If I do not have the left in, the right will not fire. I have tried the right flippers during game play leaving the left one depressed and still they do not fire.?????
What I have done:
1) Replaced cabinet switch with new one
2) Checked for proper voltage at switches and coil - passed
3) Installed new lower right coil - still same issue
4) Installed new working rottendog solenoid driver board which works in other machine - still same issue
What else should I try??? Please help!
