Quoted from pinchamp:However every solenoid in the solenoid test menu is not firing EXCEPT the idol motor.
First (stupid) thing is to verify that the high voltage interlock switch in the coin door is pushed in (closed either physically by your hand or the actuator attached to the coin door). This is easy to overlook.
Playfield motors are powered by +12VU. Flashers are powered by +20V. Solenoids are powered by +50V. I ass-u-me (these usually make an ass out of me) that the flashers are working since they are a separate test (T.5).
No solenoids? Also confirm no flippers since those are solenoids but not tested as part of T.4. I ass-u-me that the flippers probably are not working.

Check for the presence of +50V at the test point. This will read ~70VDC. It is unregulated so a precise value is not guaranteed. Rather it should be within a "tolerance" range. If voltage is absent then it indicates that F112 is probably blown.
Quoted from pinchamp:So I need to replace this board. Something else fried as well?
The 8-Driver Auxiliary board needs to be repaired. Not necessarily replaced. Repair is almost always cheaper than replace. At least, if you do the repair yourself. If you send the board out for repair, the shipping (both ways) may make the repair cost ineffective.
If you choose to replace this board, make sure you purchase a board that has the pulldown resistor modification on it. That is an important "fix" to prevent floating signals on the data bus. I can recommend some available board manufacturers if you have trouble locating a board.
For the moment, you should look to understanding all your failures before making any purchase, since you may need to make more than one purchase depending on what's wrong.
