Quoted from Blackice:Thanks I checked and I can’t see any other coil energising with kicker, now my sound has intermittent problem sometimes works and other times no sound and light on S&T board stays solid on, I noticed when no sound the kicker works.
I'm not sure how those two problems could be related other than a bad ground or maybe a leaky filter cap. What's the history on this machine? You might wanna go through each board systematically, rebuild them if they haven't been rebuilt properly, reflow any bad solder joints, check for anything suspect, specifically on the solenoid driver board.
