A year or two ago I installed the wixey wr550 on my 20" jet planer and its always worked great. Until it didnt....

I used it a few nights before Xmas and it worked like always but display was a bit dim so when I went out the next night I wasnt shocked when it didn't turn on. I put a new set of batteries in it and it turned right on, but the display would freeze as soon as you put the batteries in most of the time others it would wait till i tried to calibrate then freeze on all zeros.

I did notice the cable touched my dc hose so im not sure if maybe it got zapped or if maybe i just need to take it all apart and clean it. Can I use electrical contact cleaner on the greenboard and sensor price?

Anyone else have an issue like this?

I'm really hoping the whole thing isn't trash because although I really liked it and I had it for a while I only used it for larger stuff so I definitely didn't get my money's worth. I run most of my smaller and rough or dirty stuff through my lunch box planer
