On the Target Banks not resetting at start up, the one thing in common with the two banks
is the DB Relay. I take it that the Control bank is energizing, so juice has to be getting to the
DB make/break switch..
The chimes are remaining on, but not scoring. The score reels are getting energized, but not
releasing. Is the Score Reset Relay in the head remaining energized? If so, has to be a set of
switches in the Control Bank. Probably in the Start Relay, or there may be two, S1 and S2.
As I'm sure you know, you don't want to let those coils remain energized for long..
Edit: Score Relays, not Score Reels. Are the Score Reels energized. If not, the Relays will
remain energized..
