I am working on an X-Men pinball machine. Switch 13 (left ramp entrance) and switch 26 (left slingshot) are not working.
Switch 13 (left ramp emtrance) : the micro switch is good and i have continuity in the wires to the connector. What should i look at in the back box? Which transistor? Which board? Which component(s) on the board? Any suggestions?
Switch 26 (left sling shot) : the coil is good, the diode on the coil is good. I have continuity from the coil to the connector right below the transistor bank. I tried grounding out the transistor (Q13) to activate the coil but nothing happened. Do i need to have the coin door closed (or service switch pulled out) to do the ground out test? Does the sling shot have its own individual fuse? Maybe the fuse is bad. The leaf switches are good and gapped accordingly. There are no loose wires anywhere pertaining to the coil and leaf switchs or connectors.
switch 53 (center lock up).the center coil..(under magneto that traps the ball with two metal arms) keeps activating when the game isnt being played. For example when i turn it on it starts going up amd down repeatedly, multiple times. It eventually quits. Again no issues with wiring or coil.
All 3 issues are boggling my mind. Any help would be appreciated.
