Quoted from tomdrum:
Pulled a Gottlieb Sky Jump out of my storage unit that's been there awhile. I'm going to sell it at Pinfest and wanted to see if it worked. I haven't touched an EM repair wise in 15 years. I buzzed all the fuses and they are good. On 1st start up it reset the score and then the score motor kept running. I shut it off and reset the start relay. Game now will start and spit out a ball. Nothing however will score on the PF and the flippers won't work. Ideas anyone?
OK, a few things you neglected to mention. Is the target bank resetting? Is the rollover sequence resetting? And finally, when the ball would be sent to the shooter lane, was the ball count unit stepping up? The reset sequence of this game is not particularly complex.
If the ball count unit doesn't step up, you won't get any scoring and the flippers will not work.
If everything is resetting and the ball is not shooting up to the shooter lane, check the outhole switch, the outhole relay, and the associated motor switch for the outhole relay. If you can't find that I'll dig out my schematic and help you.
If everything resets properly and you get the ball to the shooter lane, then check the adjustment and clean the trough switch, and also check and clean the ball count unit in the head.
I concur that the main problem here is more than likely it's just dirty and the switches are corroded by it sitting as long as it did. Like cars, EMs want to be played and generally don't take really well to sitting around for long periods of time, especially if it's been in a non climate controlled storage unit.
