Quoted from HowardR:

If the 1st player doesn't award a replay when set up to do that at 101,000 Inspect and diagnose this circuit with Alligator clip jumper wires

Quoted from currieddog:

I thought it was either/or for match credit/extra ball, ie-you can't get a match credit if you have switch set to extra ball.[quoted image]

Quoted from HowardR:

If you'd like to try a phone call, send me your cellphone number in a private message and I'll make a first reply with a text message.

Quoted from currieddog:I had a SM and I see to remember that it didn't do both. I know that Howard has helped a lot of people via phone calls so go for it!!

Quoted from LeChuck:

If it does the same thing for all four players, then that most likely eliminates the big section between the two player unit switches in Howard's schematics. And if the outlane specials work when A/B/C are lit, then that eliminates the section to the left of the 1000 pt relay switch at the top of the schematic. If the tilt relay switch on the bottom/right of the schematic wasn't working, then none of the scoring above it would work .. so that can be eliminated too.
Seems like the best things for you to check are the player unit switches/contacts going in and out of the high-score logic, and the 1000 pt relay switch coming out of the high-score logic. Since you say it suddenly stopped working, you might have a disconnected wire or something else that worked loose. Not much you can do to find that except follow the wires using the wire colors in the schematics.

It could be that it locked into my head because another machine was set up that way, soo ...
