I am restoring a 1966 A-Go-Go and am having an issue with the 100 point relay.

Game starts fine, score reels reset. 100 point relay does not energize at game start so no pf 100 point switches stuck.

When any 100 point switch is hit, the 100 point relay energizes and locks on. The score reel coil energizes and the EOS opens but does not deactivate the 100 point relay. The score reel coil stays energized along with 100 point relay.

Went back and double checked all 100 point switches. Also look for short leaf connectors on switches. Stumped at this point.

Thanks for any advice and help.

Does it happen for all four players? Opening the EOS switch on any of
the four 100s score reels should release the 100 point relay.

I'd guess it's the solder tabs or some other part of the EOS switch or
its wiring that's shorted.

Here is a little more detail on what is going on.

When one of the top targets is hit, the "on bumper" relay engages as it should. Hit one of those targets a second time and the 100 point relay locks on, and the on bumper never disengages.

The other 100 point sw - top outside lanes and bottom pf outlanes - lock on the 100 pt relay when closed.

From browsing the schematic my money is on an issue with your 100 point score reel EOS switch... check that when the 100 pt drum unit pulses, the EOS opens at the end of the plunger stroke. An open EOS will effectively drop the 100 point unit from continuous engagement, since you stated it starts up fine with no 100:point pulse. Report back.
