OP

Quoted from jlarose1988:

I thought maybe one particular switch that awarded points might be sticking but it's not one switch that does it. These events are initiated from random switches in the playfield which leads me to believe the issue is most likely in the scoring reel itself.
I pulled the back panel off and identified the solenoid behind the Player #1 100 point counter. I was going to take a stab at ordering the part and replacing it but thought maybe I should start here first. Anyone experienced the same issue or just have some good advice before starting? I am completely new to this and want to proceed cautiously. Thanks in advance for any help.

Quoted from jlarose1988:

I tested the machine after cleaning the scoring reel and the issue persisted. Even worse, I tried more than one player and the problem transferred from player 1 to 2 and to 3 when it was during an event but the previous player turn ended. Clearly I was wrong about the issue being in the reel. Something else is sending the signal to the reel because it continued as players turns changed.

Quoted from jlarose1988:

In summary, it always starts these 100 point continuous scoring events at the beginning of a game. Sometimes it's when the new game button is selected but mostly after the ball trips a 500 point switch. I hope that made sense and thank you for looking at this issue. I've ordered cleaning supplies and basic maintenance parts. I've decided I'm going to try to tackle this on my own and will call in the experts if I can't get it.
