Hello All - just picked up another Night Rider (loved my first one, sold it to a friend, but missed it). Found a lot of weird things going on when I got it home. The previous owner didn't know much about EMs, so when it "stopped working right" they started replacing a bunch of coils, and making various odd adjustments.
First thing I noticed was that all of the jones plugs on the bottom board in the cabinet were in the wrong sockets. Fixed that. Then I noticed that a bunch of the relay switches in a couple of the relays were out of place, so I fixed that as well.
Here's where I am now: As soon as the power is turned on, the game goes into a "reset loop" of sorts. I've dealt with score motors spinning away before, but this game is acting a little weirder
The Score motor is spinning non-stop, but what I noticed was the #1 Score Reset and #2 Score Reset relays in the head are constantly pulling on and off. The Game Over relay is doing the same, on/off (not latching).
Attached is a snippet from the schematic that shows the #1 and #2 Score Reset relays. I was thinking perhaps the score reels themselves may be the issue, and that the switches that should be open might not be. I was going through each score reel, but I'm not 100% certain if all (3) of the switches in the score reel stack should be "open" when the reel is at "0" . It looks like on some reels all 3 switches are open at zero, on others they are not.
Anyone with a Night Rider do me a favor and check their score reels in reset position, and tell me if all switches on all reels are "open" when the reel is at "0"?
If that's not it... I'm thinking Game Over relay, Reset Relay, or Coin Relay maybe. Thoughts/Suggestions welcome. Thanks!
