I am wrapping up a 1966 Wild Wheels and was hoping to check the function of the match wheels on the playfield. They are supposed to light the A,B,C inserts in front of them when 2 or more match. On my gave they light when any 2 wheels are matched but they don't light when 3 match...Everything is scoring properly and awarding replays/opening the free ball gate, etc. I was hoping someone with the game could tell me what proper operation is as I can't find any videos of the game in play online...It may be that this is how it was intended to operate. Any help is appreciated!
