I have a Black Knight that I just started working on recently. There is a big blue capacitor attached to the Bridge Rectifier for the lamps. What are the chances this needs to be replaced? How do I test?
The second and more puzzling question is does the bridge rectifier for the solenoids need a capacitor attached? My game has a silver radial capacitor attached attached to the solenoid/flipper circuit. The capacitor is attached but it is just lying on the bottom of the backbox, sort of like it was installed as an afterthouht.
Definitely doesn't look "factory". I have never heard of this before. Why would someone install this capacitor? Should I leave it or should I remove it? How do I know if it is good? Will there be a value or part number printed on it?
The MPU and driver are out of the game right now. It did work but there were a few issues. There was a problem on the Driver board that controlled the magnasave. I also wanted the battery pack removed from the MPU and NVRAM installed.
Any help is greatly appreciated.
