I've had this game for years and it's been trouble free. .
Today I fired it up in my shop since there was a credit on it ..
Plays fine except if the power kicker coil light is lit in the left out lane.
Now if I roll over switch 28 the kicker will work fine .. the bitch is if the light is lit and the ball rolls over switch # 21 lane 4 the power kicker coil will also go off. Very odd .. the diodes all seem fine .I also reseated the plug in the backbox. The Only common wire between the switches is white and yellow ? Any thoughts on what to check is very appreciated.
Just trying to get to the source. All wires appear good ect
. Is there somewhere I should look closer ?
