Standard Coil Rating

[Drembo]

if you put the ignition switch to the run position, any of the terminals on the ignition switch will be connected to the positive terminal of the coil, except for the terminal connected to the starter.

Later 1800/ES use a standard coil like the 140's. I still say nominally 3 ohm.

Have to say if I was going to the trouble of fitting electronic ignition I’d go for a new high output coil as well, if you use a bulkhead fitting and a black coil it’s not far from the look of the original

Yes I did it once years ago when I had a spare coil/ignition switch to cut up and it looked OK once it was all painted black. I'd rather not do it to this coil/switch if I can help it and I don't have a spare. I'm going to give it a go 'as is' and see if their compatible (I suspect they will be).
