I could not read the entire post without any paragraphs or breaks, but have you put the game in switch test mode to see if all the trough switches are working?

3 balls, drop them in one at a time and make sure the correct switches are activated in the test mode.

Quoted from OpFlash:

So ran the switch test it seems that while dropping the balls in that the out hole , 3 ball trough, 2 ball trough, were working however it seems that the 1 ball trough switch would work intermittently. weird most of the time when I pressed it manually it worked and then sometimes I could be pressing it and it wouldn't register. with or with out the ball didn't really make much of a difference.

So the problem is the switch, the wiring, the contacts, or the diode on the switch.

How about a picture?

Quoted from OpFlash:

I was wondering why some switches have diodes on them?

The diode allows a "matrix" of switches, rather than individual circuits.

This saves $$$$.
