I got this Black Knight 2000 and the pop bumpers rarely popped, and when they did they were very weak. I saw they had a diode installed on one of the caps, but it was cut. The other two had none. I looked at my PinBot, and I swear I saw diodes on those, I think the band pointed toward the common wire. Anyway, I put Diodes on them, and they pop consistently but are very weak.
I was searching the 'net to find different reasons why the pop bumpers might be weak, but even after reading several posts and glancing through the manual I can't seem to get a straight answer.
Do BK2K pop bumpers require a Cap somehow instead of a Diode? Aren't these controlled Solenoids?
Thanks.
