Big Shot
Gottlieb, 1974I’m having a problem getting my Gottlieb Big Shot working. I had a technician come out to get it working and he got it going to a point, acts like it is ready to play but there is no power to the playfield after it finishes the startup. No flippers or any of the targets are energized. I also cannot get the game to start using the credit button, I have to manually trigger the start relay to get it going. Any help would be appreciated.
Quoted from Sennap1:cannot get the game to start using the credit button
If the Replay Button doesn't activate the Replay Button (V) relay, Inspect and diagnose this circuit with Alligator clip jumper wires

For a switch to work 3 things are necessary:
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening
Quoted from Sennap1:Update I traced the problem to the tilt hold relay, I’m not sure what the normal switch position is for the three switches on the relay. Can someone take a picture of what it’s supposed to look like?
If by "three switches on the relay" you mean a make/break switch; One switch will be closed while the other side is open. When you press the armature with your finger the closed side will open and the open side will close. If you find any switch that doesn't change state (make/break or otherwise) after you press it, you've found your problem.
Got the game to start and play have some issues with drop targets, but nothing some cleaning and adjustments won’t fix. The problem I’m having is that on both player 1 and 2 the 10000 reels will jump one to five times randomly after hitting some of the targets in the game. I can’t figure out what would cause that. Anyone have some ideas?
