Quoted from Justmc16:Lights didn't come on . Tapped the left flipper and they came on for a second .would stay on if I held them .
The schematic would be helpful for this. Do you have one?
Quoted from Justmc16:When. It finally zeroed out , it would start cycling through again . Sounded like a motor was still running even when the reel was at zeros . Then it would start cycling through numbers again .
There's a switch on each score reel that opens when the score reel is at zero. Most likely that switch never opens or the connections to it are shorted.
