I just obtained a HRO-500 that is wired for 240v operation. It had been sold to and used by an European owner.
The manual describes a power terminal board and how to change the wiring for 120v operation.
However the wiring colors in my unit don’t match the wiring colors depicted in the manual. Obviously 4 of the wires must be for the dual transformer primaries.
There’s also other wires for the power input, and the switching.
Any thoughts as to how to trace this out?
Following the wiring thru the tightly laced wiring harness is a nightmare.
