Tech: Gottlieb Jet Spin score reels will reset but not count up. No chimes either.
Picked up a Jet Spin. It was dead when I got it home just player 1 GI was on and backbox GI. After exercising some relays and cleaning some header pins poking around touching this touching that, I've got life. The game works other than the score reels don't go along at all with game play. I've played all 4 players and none move. It will cycle through all 3 balls for all 4 players fine.
If I manually put numbers on all the reels, when I start a game they all will go back to zero and the game plays just no scores. I'm playing in the dark with no manual or schematics yet. Hopefully someone can point me to some relays and switches to inspect/clean. It was in a vacation home for 30 years so all contacts/switches haven't been used in a long time.
Also my chimes will only go off once on the lane the ball rolls over. After that no chimes.
I tossed up a few vids for your troubleshooting viewing pleasure.
Just looking for where to go next. Thanks!
