I have a Williams Yukon that was working fine. In the middle of a game the 3 drum units on the playfield that change the values of the bonus points just stopped working. No matter which switch the ball rolls over that is supposed to change any of the reels they just do nothing. I do have the schematics if someone can point me in the right direction. Thanks Bill

Isn't there a jones plug for the reel unit. Maybe it's loose or needs cleaning? Just something simple to try first...

I'll need to see a high quality scan of the schematic from (for example) Staples ($2), Fedex ($6), or Office Depot
After checking the Klondike schematic, on the R.O. (Rollover) relay find a normally closed switch with yellow & brown-orange wires.
This switch must have a clean strong connection for the advance relays to pull in, and then pulse the award drum units.
Since it’s a different schematic the wire colors might be different.
Clean and adjust switch if needed.
