    I’m assuming that the 2.5 is accoss the secondaries and not secondary to ground or across the primaries. For a coil from an opposed twin with magneto ignition of that age I would expect a good coil to have 6 – 7k ohms plug lead to plug lead and infinite resistance from plug lead to ground. I,ve seen coil with more resistance than the 7k work well.
