Problem with mate's Gottlieb Operation Thunder

[Graham Lowe]

Any pointers gratefully received with this - the machine has been unused for years although indoors and set up but in desperate need of refurb, so we recently stripped the playfield, deep cleaned, new plastics where possible etc. The issue is that in missions 1 & 2 balls are locked in the ramp in order to gain multiball. Locking ball one launches ball 2 into the shooter lane. Locking ball 2 should give ball 3, but doesn't. Obviously the opto on the ramp is working as it senses both locked balls and says 'Eagle 3 you are cleared for takeoff', but no ball 3. Because the game was hardly used before we cleaned etc we aren't sure if this was an issue previously but can't see that anything we did would cause this. Any suggestions to sort this for them guys? Cheers

Good, I wouldn't have said it if I hadnt done it next I'd check connections on the boards, reseat eveyting

 

[Graham Lowe]

Lol, yeah, me too. Figured it may be a board issue, I'm over there on Tuesday evening so will check. Cheers.

Could be a wire of one of the trough switches. Try putting the game in switch test and see if it's finding all the balls in the trough.

Thanks, will check that too.b
