The high resistance (3.8V) is consistent with 12V coils - I was expecting something between 1.5 and 2. Compression is good so I"m hoping she will start in a couple of turns with the new coil instead of the four or five she took before. The battery is at the end of its life (runs about 6.1 to 6.2V) so I will get a new one this week also.

I should have added on the 6 volt coil + side goes to the distributor if not you'll get premature failure on points. just a thought but your compression may be low but easier to start when warm?

With positive ground + on coil goes to distributor, with negative ground - on coil goes to distributor.

Reversing should not affect points life but will reduce spark efficiency. Symptom I've seen with this several times with reversed coil wiring is harder starting when engine is cold. (Cold as in having set overnight, not necessarily winter time)
