Quoted from pinballbrian:
.how can SB relay activate at startup if big coil resets control bank.does SB relay pull back in after big coil resets bank.before game starts.
I just went through a Cowpoke, but it's start up is different than Fun Park.
I'm not sure about Funland, but for sure the SB Relay would be the very first
relay to energize from the free play button which resets the score reels and
ball count unit. On Fun Park, once the score reels are all reset to 0, and the
ball count has totally reset, the Reset Relay (also in the Control Bank) will
energize and then when the ball count steps up to the 4th position, a switch
is made from the ball count's plunger arm which energizes the big coil on the
Control Bank then the SB and Reset (known as DB on Fun Park) Relays are
reset. At start up is the only time the SB (Start Relay) energizes..
I guess it's possible all score reels run-out switches are not adjusted corrected
and/or dirty, but I would think the chances are more likely it's switches in the
SB Relay, but maybe even more likely a set of switches off the Score Motor's
cam. On Fun Park, it's Score Motor switch 4A, but maybe someone with a
Funland along with it's schematics will be able to help out. You mentioned that
score reels don't reset, but yet the Funland will go into game mode and be able
to be played. On the very few Replay Gottiebs I went through, I can't remember,
but on Fun Park (and other Gottieb add-a-balls), unless the score reels all zero
out, the Reset Relays circuitry will not be completed, and it won't go into game
mode. The score motor just remains energized letting the machine know that
all the score reels are not reset to 0..
Anyways, when you press the free play button (or drop a coin) and if the score
motor then runs, the SB relay has to be energizing, and if it then stops, the Control
Banks big coil must be energizing also resetting the SB Relay..
