Hi, I am having a difficult time here with my Dodge City. All was fine up until a few weeks back but now I am having issues with the scoring.
The 5 point rollovers work fine a couple of times but then on the 4th activation it will activate the kick out holes and will randomly score 5 - 15ish points. The roto-unit also attempts (or will) spin (should only activate on the 50 point roll overs or the lighted out lanes.
The 50 point roll overs are also affected, they score usually 15 points, but also seems random.
The holes also have incorrect scoring.
Basically everything in the area of the attached section of the drawing. I am sure there is some switch at fault in the score motor assembly but my logic is seeming to fail me on how it is all working. I would really like to understand what is going one vs randomly adjusting/etc switches.
The 5 and 50 point relays seem to be working fine, although when the 5 point issue above happens, there will be an arc between some contacts on the 50 point - it actually looks like it starts to pull in but then releases. I have checked the roll over switches, but like I said above, I think it is more of an issue with the score motor assembly, or am I wrong?
Appreciate any help/suggestions.
