Hello All - picked up a Neptune in good shape, and I'm working on cleaning it up and getting it working well again. It starts up and plays, but has a few things not 100%, so I want to sort them out.
First issue I'm looking at are the rollovers. When triggering any of the "card" rollovers (J, Q, K, etc) or stand-up targets, the appropriate relay on the underside of the playfield will pull in as it should and stay that way. No Scoring occurs though, and the chimes don't go off either. This is true of all the associated relays on that relay bank. All I hear is the buzz of the relay changing states as it should, and nothing else.
I found some other threads on Neptune, and one of them mentioned a chime issue that was related to the resistor on the Q relay. Could that be related perhaps? Thread is here:
Watching the video they included, it was somewhat similar to my problem, but mine doesn't have a scoring motor action, just the "buzz" of the associated relay triggering and nothing else.
Thank you in advance for any advice/assistance!
