Reply to "Buzzing Proto-Coupler on MTH Premier F-7 ABA"

Both couplers read about 2.5 Ohms when disconnected from the boards. Same as a known good coupler from another locomotive. Both worked normally when tested in the other locomotive.

I did not observe any obvious burn marks, loose or damaged wires so I put everything back together to retest. Miraculously, everything seems to be working now. I did switch the coupler positions when putting them back together though.
