I see that now. I thought over the course of working on this thing I had probed it every which way with an ohm meter. There is nothing between 97 and 98.
I think the code people have moved on. I don't see a problem interrupting L2 at the pressure switch also if that is what you mean. Anyway this is Texas and just about any electrical work goes here. I recently remodeled a house where the homeowner hired an electrician to run a wire for a new kitchen stove some years before. While I was there one leg of the wire went dead and they had me look at it. I found the guy had pulled an aluminum wire tighter than a banjo string through the attic and down in the wall and wired it without a breaker directly to the electric meter. Then someone later on had the bright idea of using wood shavings for insulation in the attic and the wire was buried in it.
