Ok, i have this old Star Trek Bally machine. I have worked off and on with it. Right now i am having a problem with the solenoids. Ill give my two examples.
It should be noted this machine has a brand new MPU and sound board. I am not noting any problems on voltage with the test points on the board.
1st with an old solenoid driver board in, the solenoids are firing during the sounds. I have checked connections on the solenoid board with no obvious issues. The flipper solenoids have 45 volts each at the three points.
2nd i bought a new solenoid board and installed it. Now i have no solenoids firing except the coin door sounds like it is doing something. The flipper solenoids again have the 45 volts.
Am i missing something? I am wondering if these flippers are wired correctly? They seem a little rough. It has worked before but not now.
Thanks for any help and advice.
