I have a switch problem on my Bride of Pinbot. I have been following the test procedures of a really great article on switch matrixes by Pinballrehab http://www.pinballrehab.com/1-articles/solid-state-repair/repair-guides/146-switch-matrix-theory-and-troubleshooting#comment-362
So far I have checked the CPU board by using the jumper test on J209 and J207
I have confirmed continuity of the send and return wires of the switch matrix column 5 grn-blk.
I have tested the switches and diodes for continuity and this what I have found
Note, in my testing I first tested across the switch the send and return terminals and keeping the test leads in the same position tested the diode. I then reversed the test leads and tested again across the switch, then across the diode and recorded the results.
Column. Across switch. Across diode
SW # 1st/2nd. 1st/2nd
51 spinner. Y / N. N / Y
52 shooter. Y / N. Y / Y
53 Ur jet bmp. Y / N. N / Y
54 Ul jet bmp. Y / Y. Y / N
55 low jet bmp. Y / N. N / Y
56 jet sling bmp. Y / N. N / Y
57 left sling shot. Y / Y. Y / N
58 right slingshot. Y / N. N / Y
Any help interpreting my test results would be greatly appreciated.
