Afternoon all. Williams BSD Altar vuk activates even when no ball is in there.
Thinking this may be faulty optos in the trough but would like someone with superior knowledge than me to confirm before I start fitting new optos.
Thanks for any info than anyone can give on this. Cheers.
Is it Ac or Dc Andy?Measure volts across the white opto sender. If higher than 2v opto is bad , if lower than 0.5v there’s no power getting to it. If in between then check the wiring for the receiver.
Thanks but not 100% sure what I’m looking for when you say that.Put it into switch test mode and see which switches are showing active. Bang on the playfield also to vibration check dodgy connections.

Got it thanks. When the light beam was interrupted the switch showed up as working
