KMB-1 machine was in a 230vac shop, ours is 208 so all my voltages are at the absolute minimum and I'm having problems. I started to reconnect the tap wires on the Square D transformer to boost the input voltage and SURPRISE no visible labels on the wires coming out of the trans. I cleaned several wires as best I could but all I can see is wire gauge and "BELDEN" on any of them. I've been chasing gremlins on this machine on and off for months, just when I get 1 thing figured out something else shows up.

I've worked on these things doing minor repairs for over 20 years but this one is possessed.

I'm going to check wiring on another KMB1 at my other job and see if I can make a semi-educated guess on wire identity.

Any other ideas?
