Multimeter coil readings

Just bought a multimeter , the instructions for the starship enterprise would be easier to understand , based on attached photos are these coil readings normal , I'm half hoping they aren't as starting is becoming a problem

Thanks

A bit difficult to read but I think you are getting 3.6 ohms on the primary. Perhaps a little high as it includes the resistance of the leads & test prods. When you measure it again note the reading then connect the test prods together & it may read 0.3 or even 0.5 ohms you need to deduct that from your reading on the coil primary.

It looks as if you have turned the switch to a kilohms range in which case it is 6.22 kilohms or 6,220 ohms. A little lower than most of my coils but still probably ok. With such a high resistance measurement the odd 0.5 ohm from the test leads is insignificant.

Just went through this exercise finding a dud coil on my 109. 3.x ohms is OK for the primary and the 6.2K for the secondary is fine as well.

Coil is probably fine. Check from the metal in the king pin to one of the terminals that should measure <20k (i.e. 20,000 put it on the 4th resistance setting). More likely to be points, condenser, plugs or leads...or not ignition! A simple multimeter check won't check for shorted turns in the coil which is a typical failure mode. Easiest test is to buy another coil and try substitution or find someone with an oscilloscope who knows how to ring-test coils.
