CDI resistance test.

I tested my black wire on my CDI to my spark plug cap and it reads 7.10-7.15. My multimeter is set at 20k ohms. I read that it should be around 2.3. Is my CDI bad since it reads high?
 
no, due to capacitors inside and a full wave rectifier, it makes a difference which meter lead is on which wire - also, the meter cannot test for whether timing is right

if you don't want to build a big tester for CDIs, then best to try a known good one to see if it helps
