Ign. Pick-up

Have I missed something here ......
Today I was going to fit a new Dizzy pick-up and base plate unit ( Rimmer part No. RTC 5090P1 ) this is OEM unit NOT the "Britpart" cheapest or the Original very expensive unit either, a middle range job? At £80+ it should be a decent replacement.
Before I begun to fit this unit I checked the pick-up for a resistance test using a very good multimeter, the one in the car reads 3K2 Ohms (3200 Ohms) and it will help produce a spark though it is playing up. I have tested my amp and that is perfect. My amp is a £25 - £30 job from a motor factor and has worked well for at least 5 years with the 35DML8 dizzy.
The resistance test on this new unit produced a Zero reading so I tried a continuity test and that also produced a Zero reading.
The pick-up itself is just a coil surrounded by a magnet, therefore the coil sits in the middle of a permanent magnetic field. Disturb that magnetic field with metal very close to - or touching the coil with it - and a very small AC voltage is produced. A very, very basic principle .... but it works
Would you the reader think as I do the pick-up coil is useless? No continuity and no resistance either through the winding.
What, if anything have I missed?
Many thanks ....Mike
