I'm beginning to understand why even simple British electrics are so confusing to many.
I was just studying the schematics in the factory WSM for my '72 T120V.
Looking closely at the rectifier bridge I noticed that they have one diode backward in the diagram for late models. I checked the diagram for the early models and two diodes are drawn backwards. That's not a rectifier, that's a ring modulator!

Stepping on others doesn't make you stand tall.
