equeen........compression is "O.K.", NOT chur problem.
You ask........"Two different coils tested, not attached to distr: 6.2v negative post in, 6.2v from tower, 6.2v positive post out".......this is NORMAL for roundcan coils. Ittza LAW, Kerchoff's Law. Yer coil is what is classed as "auto-transformer" meaning ALL the turns are connected together. HOWSOMEVERS iff'n you "ohm'ed" between 2-terminals you'd read about 2-3 ohms for the primary (battery) turns and about 1700-ohms fer the high sparkie term (center term)
You complain......."No voltage reading on side post of distr. (Sounds like a solid short in distr now???)" Iff'n yer points are closed, you will NOT read volts at the feed-thru. Ittza LAW. Kerchoff's Law. HOWSOMEVERS, the plastic feed-thru can also SHORT and you will also read NO VOLTS. Points must be OPEN (visually inspect) for volts at the feed-thru. ........Dell, yer self-appointed sparkie-meister
