Hi ncsujeff
does Your pin has the "Reset-Relay" --- later Williams pins start-up: Throwing-in a coin worth a game makes the Coin-Relay (better name would be "Start-Relay") to pull-in. If we press the Credit-Button then a Credit-Relay (makes the Credit-Unit step down) makes the Coin (Start) Relay to pull-in.
The pulling-in Coin-Relay makes the Reset-Relay pull-in --- as long in time this Reset-Relay is pulling: The Motor runs and Score-Reset-Relay(s) are pulsed - the Score-Drums are stepped towards Zero-Position.

(When You have an Reset-Relay) AAA: As the Coin-Relay pulls-in - at the same time press the armature of the Reset-Relay and let go - what happens ?
(When You have an Reset-Relay) BBB: As the Coin-Relay pulls-in - at the same time press the armature of the Reset-Relay and press, press, press - do theScore-Drums reset ? Greetings Rolf

Hi ncsujeff
I dream of "You do the AAA" --- the Reset-Relay establishes "Self-Hold-Current" means stays pulling UNTIL all the Score-Drums are resetted.
IF (if, if) this is what happens: We then could concentrate on the question: "How (wiring) does the pulling Coin-Relay lets current flow to the "Coil on Reset-Relay". Greetings Rolf

Hi ncsujeff
we need the schematics. See in the JPG "Full House": The pulling Coin-Relay closes (encircled green) its switch - the Reset-Relay starts pulling-in. The Reset-Relay establishes Self-Hold-Current by closing (encircled orange) its switch. The Reset-Relay stays pulling until all the Score-Drums (encircled red) switches open as they reach their position-Zero.

On the bottom of the JPG You see "encircled blue": The motor rhythmically closes its switch because the motor is turning - the "Switch on the pulling Reset-Relay" is closed. AND (in Full House) - encircled brown: The Coin-Relay must have quit pulling so its switch is closed.

Want to try --- do not start a game by pressing the Credit-Button - do not start a game by pressing the armature on the Coin-Relay --- do: Press the armature on the Reset-Relay - try "press and let go" as well try "press - press - press".

A picture taken with an mobile phone camera of that area is good enough ---but we must see the wiring in YOUR pin. Greetings Rolf

Hi ncsujeff
I bet a lot of pinsiders would like to see the complete schematics of Teacher's Pet - a classic Williams pin.
I show for orientation the area on "Full House" - the Replay-Unit-step-up-Coil and ALL the wires to this coil --- in some way Your "Special feature" makes the Replay-Unit step-up. Please take an mobile-phone-camera picture of the area on Teacher's Pet - and we look at it.

Two general rules are:
The "Power-only***" Coil on a flipper-bat is allowed to (fully) pull for one to two seconds --- if it pulls longer in time the coil will overheat and burn.
All other coils on relays and steppers are allowed to constantly (faulty) pull for one to two minutes --- if they pull longer in time the coil will eventually overheat and burn.
When we do testing we are ready to toggle-off the pin - we do testing for ten to thirty seconds - maybe to one minute or maybe to two minutes - but then we must toggle-off the pin and let it cool-down.
"Power-only***" Coil - as the flipper-bat moves: At the end of moving the bat opens an EOS-Switch - so a second windings also is in line --- and the second windings has high resistance hindering the Power-only*** Coil to suck plenty current - now the Power-only*** Coil cannot overheat. Greetings Rolf
