But an ohms test between the RED and BROWN wires would reveal but a fraction of the resistance reading between BLACK.

( I may have guesstimated / assigned the last two colors backwards). wiring color coding scheme.***ĭoes it not look to you, that the AC power line input connection would be related to the BLACK-BROWN-RED wires to the right side of the photo.*** With Black being the NEUTRAL connection and and then an optional LIVE wire connection to either BROWN for 240VAC input or RED for 220VAC input. Now with the additional input from some of youse You-are-a peein' guys on 230 V. with a variable thrown in by any subjective long time humidity averaging being experienced. THIS transformer then would date out as being of about a 1998 vintage. as is being verified with a scanning electron microscope.

In its highest level of oxide deposition. In initially examining the accumulated layer of iron oxide on that one particularly affected E lamination.
