Which Coil?

My coil failed last year and was replaced by a helpful AA guy who had to ring around to find a replacement I have a nagging dought about whether it's correct. Measuring between the poles I get about 1.25 ohms. I think this means it's a ballast type? The reference number is 11330-B which also leads me to think it is. It's a Sierra 1.6 based car. I believe this was a ballasted system. However measuring the voltage between the positive feed and earth gives 12v with the ignition on , which implies non ballasted. Am I measuring this the right way? I'm thinking I have a ballasted coil on a non ballasted system so the coil will fail? Any thoughts?

I am under the impression that all sierras had electronic ignition.

Certainly the 2l NET pinto from my 83 doner had electronic ignition with a bosch distributor.

These used a low resistance coil and controlled the curent in the electronic module to avoid burning out the coil.

Thanks for the reply. That makes sense. I was going by various guides that say a 12v feed should go to a 3 ohm coil but didn't take into account the role of the electronic module. Hopefully I'm safe. I have an old coil which seems to match the resistance of the new one. I'll keep it in the car just in case.
