Hey guys, while I await the arrival of my schematics for my sky jump I happen to have a new problem today. I noticed that when i hit the flipper button the score starts to increase on the tens reel and chimes as well.. so I opened her up and noticed a loud humming noise.. I also noticed that one of the chime solenoids is staying energized all the time. I noticed this because I took off the chime plates and the rod in the solenoid is in the up position all the time. when I pulled it out obviously it was hot. So I checked all the connections, plugs and it looks like everything is good to go. but it definitely is a constant open connection somewhere. anyone have any ideas where to start looking.. thanks.

thanks.. Im off to go look at those things you mentioned now. in the mean time I found a brown wire not attached to anything. It is bundled with the wires attached to the drop target assembly. I also noticed that there is no wire on the right drop target solenoid wire node.. I attached these pics.. maybe someone with the game can tell me where this wire goes and if there is supposed to be a wire attached to the second connection on that solenoid.

ok you were right, that 10 pt relay in the head is definitely locked on. I can pull it back and watch the chime solenoid de-energize. now the question is " what is making it lock on?" I checked all the play field switches and they all work, and the slingshot seems pretty normal to me.

Ok i wired it up, but did not make any difference. It’s still a open short on the 10pt rewlay somewhere

Ok i did this and yes, once i remove the plug in the head the problem goes away

Ok well i figured it out ( with your help of course). Seems like the rubber band on the inside of the drop targets was shorting the 10pt switch inside the drop target area. I realigned the band and poof.. gone.. thanks for the help. !!

I just want to say thanks so much for all your help guys. This is my first EM pin and I have learned a lot already by posting and receiving impute from the experts here. I have been building and restoring arcade machines for years, so moving to the EM side of things is really daunting, however I am loving it. Thanks again!
