Title: Help me properly name these diagrams.
Post by: Greg G. on March 26, 2014, 04:16:42 PM
For some reason I've got them named as "302-for-subset" diagrams, but I'm not sure that's correct.  The obvious way is what the diagrams say, but I guess I'm wondering why I named them as "302-for-subset" in the first place.

They are both properly labeled at the top of the pages in bold print.  They are both for 634 and 684 subsets.  One diagram has the old 146A induction coil and the other has the newer 101A induction coil.

Both subsets are electrically equivalent to each other, and the 302 as a subset is also electrically equivalent to a 634 or 684 subset.

So I would label the one that has the tubular induction coil (146A) something like "634 - 684 subset with 146A induction coil", and the other one that has the transfromer like induction coil (the 101A) something like "634 - 684 subset with 101A induction coil"

"634-684 with 101A or 302 base as a subset"

Leave the other one as is.

I didn't mean I wanted to change the label on the diagram itself, just the file name I gave them so I'll know which one is for wiring a 302 subset.  Perhaps I erred, and neither diagram would be a useful reference for wiring a 302 as a subset?

The diagram with the 101A coil most closely resembles a 302 base, so use that one.
