I rewired a machine to 220v 3ph and its not working, I have tracked the problem to this transformer, and not sure if it can be re-wired to 220v. Initially I thought its only purpose was to provide 110v for a worklight, but it also provides power to the Sprecher Schuh contactor coil, which sends power to the main switches. With power on I can manually move it and it will hold, power reading between the 0 and 110 terminals on transformer is only 77v. Can this transformer be re-wired to output 110v by rearranging taps 1 thru 4? Voltage readings on those taps are in the last pic.
