OP
Quoted from Brewchap:

The Bonus Hole Eject and Open Flipper switches is the last two problems that I know of so far. I'm hoping that the problem for the two are related. Pushing on the Bonus Hole Eject will light up some lights on the playfield, but it will not fire the coil. The coil does work when grounded. The Open Flipper switch does nothing.

This is the circuit to check for the Open Flippers. And for the Bonus Hole Eject, it is likely the score motor sw. The schematic has a blur so I can't tell if it's 7B or 7D.

On the score motor, do I count the number of switches from front to back, then the stack of switches from bottom to up?

The motor looks like this, with cam numbering going from L-R and lettering from bottom up.

It's 7B. I found the relay for the Bonus Hole Eject and when I push the switch and then push the relay, the score motor turns and fires the coil. But it still does not fire just pushing the Bonus Hole Eject switch.

By BHE sw., do you mean in the eject hole itself? If so, have you checked the sw. under the PF for cleanliness and solid contact?
