I've had an ignition fault which I've solved but during the troubleshooting I measured the resistance across the ignition module of the 65DM4 distributor.
The book says it should be between 950 and 1150 ohms. Mine reads 81.5 on the 200k scale and a spare module (no markings on it at all) I have a reading of 15.2 on the 200k scale. Are both of these suspect?

As both modules are giving a different reading then both are suspect, I'd not risk any second hand unknown modules, and new ones are not that expensive, By the way lots of modules are killed by the wrong coil !!
