I have a start sequence issue I have never seen before where I cannot find a switch, looking at both the schematic and on the playfield. My Williams 1970 Jive Time has a switch stopping the start sequence. It's called the KICKER SW (N/C). It need the yellow common to work. If I jumper the common it works. (The attached shows the circuit where the Coin Relay closed and locks the Lock Relay, thus providing a path at the yellow common, through this Kicker Switcher!)
There are only 2 kickers for this machine, called Auto Kickers, used for the Spin function. I verified this with the manual as the only reference, which are for two coils. Reviewing all the text and wire colors for the motor switches show nothing. Looking at the the switches on the playfield don't match the wire colors (yellow & block-orange).
I even bought an original schematic -- in poor condition but it hasn't helped. Any suggestions?
