I could really use a picture of the chassis wiring for a 40-88. I’m having difficulty reading the schematic and I didn’t take pictures when I began replacing bare wires and especially from the on/off volume pot. Any reference pics or info would be appreciated.

This might have a clearer schematic:

Download the check mark for 1940 then scroll to page 80.

I think they all come from the same place...

The power switch is pretty standard fair for a battery set. It disconnects the A+ and the B+. This insures no battery drain when the set is off.

Thanks, I was able to get a better schematic.
