The cap in there had a silver end and a paper end with only negative signs on the case so I have no idea if this was installed correctly. I may not be understanding the antique cap symbol here. Was there some convention here with the negative signs on the case?


I read that symbol as the bar being positive and the three sided square as negative. Judging from 40 A. So I’ll read the metal end of the cap as negative.

So the positive end of the cap goes the connection to the field coil. The yellow wire in the foreground runs up to the speaker coil.

The negative end goes to the termination of the 470k resistor with the yellow green wire.
