MG MG Y Type - A good coil?

There is a way you can check whether a coil is a good one (windings etc.) or not using an Ohmmeter but for the life of me I cannot remember how to do it.

I have a couple of original coils and I want to see if any of them are any good. Can someone remind me how to do it please?

Thanks

With all wires disconnedted from the coil, measure the resistance between the two side terminals with an ohmeter. The reading should be in the range of 0.75-0.81 ohm.
Test from either side terminal to the center high voltage terminal, and the reading should be 10,000-11,000 ohms. Any significant difference would suggest replacing the coil.

Thanks Bro' - my multimeter isnt that fancy, but it essentially shows 0 ohms across the two terminals and 4-5k ohms HT (High Tension) to SW (Ignition switch) side terminal. It is an original coil so would this be a fair reading - it doesnt have to produce a spark that could illumin the East Coast when it lights up?

Paul,
I think you need to borrow a digital meter from someone.

Paul,
I don't think they would let me on the plane with one!

I'll bring a meter when I come to Bellingham.
