Recently picked up a working Card Whiz which is set on 3 ball. Everything works and scores properly but when ball 2 gets ejected into the shooter lane the "double bonus" light comes on and when the ball drains it scores double points and stays on for the final ball which is normal. When starting a new game the light stays off for the 1st ball. Everything by eye looks good with the "I" and "KY" relays. Thanks for any advice that can help.
