HowardR - I did what you said and jumped the #1 Rollover switch directly to the (D) Relay and then ran my finger over the rollover, it advanced bonus by two positions. That said the KS Relay was the problem.
Just a couple of days ago, I completely cleaned the KS relay - it was not advancing the "Extra bonus" light at all. And now the light was working, so I thought it was fixed. I couldn't figure out why it wasn't giving me the 2 bonus advance. So I did a test, running my finger over the other, unlit rollovers, and was surprised to find that one did give me two bonus advance. For example: the #2 Rollover was lit but only gave me one bonus advance. But when I ran my finger over the #3 Rollover (unlit), I did get two bonus advance. I activated the spinner one position at a time and found the rollover that gave me two bonus advance was always the one RIGHT NEXT TO to the lit rollover. Not sure why.
So I took out the KS relay and again took it apart. I manually activated the armature and noticed that there was one spot on the cam where it would get stuck. (Before I cleaned the ratchet, it got stuck every time it approached the "hump" in the cam - where the switch opened up. The photo is from a previous thread.) There are 5 clicks through each "hump" and 4 humps, so 19 out of the 20 clicks was fine, it was just the one spot where the drive finger wouldn't fully advance the ratchet. So I thoroughly cleaned the ratchet again - got out every single speck of dirt in the ratchet teeth - and put it back together. It worked. Now the KS relay operates flawlessly and the lit rollover, whichever one is lit, scores the two bonus advance.
Not sure why it was lighting one rollover and giving two bonus advance for the one next to it. Any guesses?
Thanks for solving this one for me!!
