Quoted from baldtwit:
the bank reset should probably only happen on the first coin.
it's hard to tell what's going on without knowing what the relays are, especially the relays in the bank. Can you post pictures of the relay labels for the bank and the long row of relays down the middle?
also a pic of what you are doing to the game relay. You're on the right track as the game relay controls the reset relay which controls the bank reset.
the score motor has a "service switch" ... you can open/unplug the motor then turn the cams by hand and see what happens in sequence. Don't stop turning the cams while the bank reset solenoid is powered or you'll blow that fuse.
The relay names on the bank, looking from above and left to right
Game relay, game over relay ,2nd coin relay , 3rd coin relay , 4th coin relay
The relay names on the ground board from back to front
Coin relay (110 V) , Replay relay (110V) , reset relay , outhole relay , ball index relay , player reset relay , left target relay , lock relay, tilt relay
