Hi. I am in the process of fixing a Gottlieb Gladiators. I have noticed that when I turn on the game the moving ramp is always moving, and the motor is very loud. I do not have access to the game manual, so I don't know if this is a setting that's wrong, or what could be wrong. I haven't played the game before (fixing for someone else) but from watching youtube videos, the ramp is not supposed to always move. So I guess I have two problems:
1) The ramp always moves
2) The motor is noisy.

Does anyone have any thoughts on how to fix either/both of these problems? Thank you!
