This is on Heat Wave . 1964 Williams
On powering up the machine, the tilt relay and the game relay go into locked position. The other relays on the relay bank don't.
On starting a game, the bank of relays resets. The tilt relay and game relay go into locked position. Is that correct? The score motor begins to cycle, then stops. The game shows Tilt. Lights are on, but the no bumpers respond.
Does this sound like a tilt relay issue? If so, which of the switches should be open or closed? All I can find on the schematic is one switch that looks to be normally closed. I can't find any of the others in the stack on the schematic (if I even found the right one).
The game was running fine until I rebuilt one of the red (no. 2) pop bumpers. But the wiring is correct. I checked the wires against the pictures I took before disassembling it.
