Quoted from mrossman5:I really appreciate your reply. It is definitely possible it is the motor board. Everything else on the battlefield works. Here is exactly what happens:
I turn the game on, motor is supposed to move the paddle from one side to the other to make sure it is working, but it doesn't do this. I go into switch and coil test and find that everything else works fine (drop targets, switches, and the coil to kick the paddle). Going into battlefield test, it says there is something wrong with the motor (it doesn't trip the two opto's because it isn't moving). When playing a game, it knows the motor is bad and will not allow the ball to enter the battlefield VUK (target stays up).
When the motor works, it works great. It's smooth from side to side, and successfully trips the two optos.
Remove the motor from under the min-PF but still leave it connected - then run the mini-PF test and see if the motor turns. If the motor works, then there is an issue with the gear or kicker sled; if not then you need to test if the motor works (if you have a 20v DC) or otherwise look at/ replace the motor controller PCB
