Before I sell it for scrap... KX220

I think they work on 10V. you could try and shift the potentiometer so that it uses a different position, in other words it shifts the wear marks. It means you will have to recalibrate your positions. I hope that is clear.

I appreciate all of your responses, truly. Currently I have had the machine running for a solid two weeks with no issues. All voltage is of course reading properly as the machine is running properly. This has been the issue for nearly two years now. Sometimes it works, sometimes it doesn't, and even the Kawaguchi tech I mentioned in the first post doesn't have an answer. Keep in mind also that it isn't just one potentiometer that fails or even two. There are four and they either all work or they all don't. This is what made me think it has to be a board but the replacement board didn't change anything and the entire rack of boards tested OK. Once again I do appreciate you folks even taking the time to respond and offer your help and insight.
