I have a 220v 5HP, two cap (25 and 216-259) single phase on the bench with four bare copper ends sticking up; two thin (start) and two thick (run). I removed all five wire connections; blue + blue to the thick RUN winding, black + orange to the thin START winding, and the other thick + thin + red wire, which is the common, thinking I was isolating the two windings so I could affix fresh connections. As I expect, the heavier gauge (run) winding measures 1.2 ohms and the lighter gauge starter winding measures 6.2. BUT BUT BUT there is approx 7.2 ohms between either of the thin and thick leads! I thought they were supposed to be electrically separate? What am I missing? I thought the 7.2 ohms should only be measured between a single thick and single thin, when the OTHER ends of the windings were connected, effectively measuring the ohms serially, for both windings together?
