Been working on my Slugfest getting it fixed up for the holiday season.
I've been spending time trying to get the ramp working right. Here is what is happening.

The opto stops registering. I have tried all of the following:
Replaced the Opto board
Replaced both the transmitter and receiver optos
Added lockwashers to the opto screws to stop them from coming loose and causing the optos to shift.
Resoldered and tightened the wires on the connectors and motor.

In all cases the ramp works fine for a few games, maybe a dozen innings, then the ramp optos stop registering. After I do another of the above the same pattern, ramp works then stops.

Only two things left I guess, Replace the connectors with new .156 headers and the MPU. Did I mention this is a repaired MPU that had some battery damage at one time. I would like to avoid the expanse of an MPU, what other ideas do you have?

Thanks in advance, Big Al from Chicago.
