I have checked all fuses, ran diagnostics and all other kickers and switches are working fine.

I have tested the coil, it shows 3.4 ohms so it isn't open or shorted. Resoldered the wires to the coil just to make sure I have clean connections.

I hear a click from what appears to be a yellow relay on the aux power board, but not voltage goes to the coil.

Very frustrating as it worked fine last week.

I'm a hands on guy so if I know what parts I need to replace I can do it. Don't want to "shotgun" everything and prefer not to remove aux power board from cabinet. (The less disturbed the better is my thought.)

Thanks

No need to shotgun anything. There are tests you can run before you even think about changing parts.
Williams system 11 games, in order to have more "stuff", utilized a relay, called the A/C relay. When the relay is de-energized some of the coils get the power, where if the relay is energized the power is diverted to some of the flashers. If you look on page 28 of your manual/schematics you'll see that the outhole kicker coil is switched with LF Wheel(p) & Jackpot flashers(b). You say that the other coils are working, so I believe that the Aux boards is probably not the problem. Power is always going to either the coil or the flasher. Check each one to see if you're getting voltage on one or the other. If you are, go into diagnostics mode and test those flashers. If those flashers are not triggering either, then you may have a problem with the associated transistors (Q33) the TIP122 power transistor or (Q29) then 2N4401 pre-drive transistor. With the game off, you should be able to test them. If you've found the TIP122 to be bad, replace it with a TIP102 (it's a more robust transistor).

...and also make sure the diode is good
otherwise you might shoot yourself in the foot!
 
Have you checked to make sure its not just a connection issue? Alligator clip to the coil's lug on the NON-banded side of the diode, then momentarily touch the other end to the side rail of your cabinet. If it doesn't make the coil kick, then you have bad connection somewhere. Could be a anything feeding from the coil to the harness, to the interconnect board or the MPU. Check that out first.
