Guys;

That link shows how to test typical (three terminal) coils, stating: "...testing procedure is valid for just about any automotive coil".

What it should say in addition to that is: ...EXCEPT for vintage Volvo coils, which require no ballast resistor, and are permanently connected by way of an armoured cable, to the ignition switch. Because of this, the resistances indicated are hardly what I would expect, even if you could get to some of the connections.

IMO, the best way to check them (short of test-installing them into a car), is to wire them up to a battery per a 122 wiring diagram, an to put the output on a spark-plug (no distributor required, but substitute a momentary pushbutton for the points).

Cheers
