Have an astrodome that will not score any 1-9. Scores strikes and spares but nothing on the 1-9 reels. Doing relay manually will register on reels. Does this on all 6 players. Any suggestions?

The scoring relays aren’t getting a strong enough pulse from the wiper fingers to the rivet disc on the score motor. Clean and shine up rivets and apply thin coat of Teflon gel lube.

Yes, always good to clean and lube the Score Motor's wiper. Actually, also Flash Motor and
all Step Up Units..

Okay, so the 1-9 Score Relay isn't getting the pulse.
Strikes and Spares registers okay, so we know the 1-10 Relay (there may be a #2 1-10 Relay also on
your machine) is energizing. When the 1-10 Relay (in the Relay Bank) energizes, a set of switches
open which opens the circuit to the 1-9 Score Relay so the Score Motor's rivets aren't energizing the
1-9 Score Relay when a spare or strike is being registered. If those set of switches aren't making
good connection when the 1-10 Relay is in the latched (reset) position, the 1-9 Score Relay won't
pulsate when it should..
When the 1-10 Relay(s) are in the reset position, I'd clean the contacts that are now closed, and also
make sure their making good contact..
