High Falls, NY
Quoted from Spanishsilver:Changed out rollover switches and series relay coil. Seems to only be A rollovers and K and Q targets. Also cleaned RS and KS relay. On rollovers there is a big blue spark when ball rolls over. Its on bottom contact on rollover.
Usually, that means you are not getting a good contact there. Sometimes used as a diagnostic 'ol' skool' technique on the motor board. (checking a faulty event looking for a large arc/spark, can be on the motor switches themselves) Not always the case, but I have solved several problems that way over the years......
