Seth,

You mentioned that you tested the transistors and they all tested good. What about the pre-drive transistors? If those are bad, it could be the issue.

Quoted from pinballholder:

This is where I show my greeness
What and where are the pre-drive transistors? I tested all 8 that were on the Aux Driver board (four are for the flashers and the four for the solenoids that are not working) but haven't tested any others.

The pre-drive transistors are in a horizontal row under the transistors. you should be able to use the continuity setting on your multimeter to trace what transistor they go to (I do not know off hand)

If you need more help, I can stop by this Sunday and get you all set. I fixed a similar issue on Henry Nanjo's STTNG about a year ago.
