Wow, so frustrating now. I'll bet it is something obvious and I just can't pinpoint the problem.

Checked the Tilt Relay and the Outhole Relay and to me, I can't see anything that is obviously wrong. Checked all wires are soldered on and gave the contacts a light sand to get any black off them.

Will continue to look at the startup sequence and the schematic.

The only thing I haven't done is checked the outhole coil by taking the apron off. Have tugged on wires underneath playfield and can see that they are on the coil, but it wouldn't hurt to check properly.
