Picked this machine up 2-3 weeks ago as a project. The “runners” weren’t advancing, the base lites didn’t come on properly, but the Vari-Target worked. I finally have runners advancing like they should for each type of hit, the base targets light up and put a man on like they’re supposed to, but the Vari-Target has stopped resetting. The U relay just sits there and spasms -like it’s opening closing rapidly. In my adjustments, I also adjusted the switch that rides in the Bakelite and closes when the Vari-Target is activated - they were uneven and dragging horribly.

I’ve checked the contacts on the U-relay, they close properly when it activates, and I’ve reset all of the switches on the motor in my other switch cleaning/setting efforts, and have double checked the one at 2C on the motor. Coil resistance is 32 Ohms.

What am I missing???

Yes - 24 volts from the orange wire on the lockout to the brown-red wire on U trips the relay and it stays tripped until I remove the jumper.

Hi Lee, thanks for the help. I tried what you said. The U relay is cycling in a deliberate pattern with the motor, but it’s like the signal is late on the white-silver wire (1c, 2nd from the inside) that connects through U to yellow black that resets the target. If I hold the u relay closed as it cycles, the target resets. I was going to post a video, but I guess I can’t.

Totally new to the EM world. If I check resistance across the switch with a multi-meter and it’s close to zero, it should be good...yes? All of the switches on 1c, 2c, and U pass this test when closed.

Lee, that got it! The zero position switches weren’t fully closing.

Now...it Tilts. I tried to play (with kid gloves even) 4 games and never made it past ball 3. Always on a single, but not every single, but always either a Vari-target or the left single flipper lane when it happened, and I think a man on third, so a run would be scoring. I’m at a loss as to where those circuits would meet up. It didn’t do this when I started, and I haven’t even touched the big relay bank in the back were the XB relay lives. The Ball In Play unit does take a little bit (5 to 60 seconds) to reset when you first turn the game on, but I was going wait to tackle that until I had everything else working. Since both the Tilt and Ball In Play touch the XB relay, could these be related?

That did it. It was the switch in the head. I had thought I’d found them all, but never occurred to me there would be one back there - makes perfect sense why it’s there. Thanks for your help and have a great holiday!
