i think i figured it out. I made sure the extra condenser I had was drained or shorted out. I set my meter to ohms. You then touch one point to the lead condenser wire and one to the (ground) or condenser body. It read (OL). I then switched the meter points around and did the the same thing. It red (OL). According to what I researched That means its good. It did come off a good saw with spark.
What I did find out is I have a bad coil on a saw Im working on. I first experimented with the meter with a good saw with nice blue spark. The secondary windings read (6.69 OHMS) witch is good according to online researching. I then tested the bad coil. The bad coil primary windings have a good reading. Then I tested the secondary and there was no reading. There must be a break somewhere In the coil. I have a new coil ordered.
I can't tell for sure from the picture, but it looks like it has a capacitor function. If it does then you would just touch each lead to the capacitor and it should display something line 20uf. Make sure nothing like your fingers are touching the capacitor. I think you will have to go into the functions and find the right setting to read capacitance.
You are off by a few orders of magnitude. A typical condenser for a magneto/points ignition system is about .22uF (microfarads --10 to the minus 6 Farads). Unless the DVM has the capacitor test ranges on it, charging/dis-charging with then 9 or so volt battery it will only tell you if it is not shorted or open (using the OHMS/resistance function cited). When the condensor is operating in circuit, it can behave entirely different under rated voltage; and could be starting to short circuit/break down. Most condensors on magnetos are rated in the 200 to 400 volt range.
