Ignition Coil Testing Nitty Gritty

I think the 20 ohm as mentioned was a typo. most digital meters have a 200 ohm as the lowest scale.
When you do any ohm checking it's best to use a scale above what you expect to get. the primary on most coils is less than 5 ohms so the 200 ohm scale will give good results. Secondary are often in the 8 to 10 K ohms range so the 20 k range will give good results.
If you have no idea what sort of results you should get I have found to start up high and work down the scales till you get a reading that appears to be reasonable. One without any error messages or a decimal point.

So the primary circuits show higher than spec resistance at 5.6 and 5.8 ohms vs the spec of 4.0 so given that and having eliminated so many other possibilities that could be causing the miss i am going to replace the coils and wires and point while im at it even though i think they are fine they are cheap

I did end up replacing coils, wires, spark plug caps, point and condenser - I still have a high rpm miss.....
