Try it with the meter on the low ohms setting for the primary and a higher setting for the secondary so it'll give a more accurate reading. If you can unhook the triggering module while you're testing it would be helpful also.
that's one beautiful saw ;o)View attachment 444883 Just did an electronic ignition conversion on this lil' guy last weekend. $21 STIHL module and a few minutes time. Runs like a champ again.

the chrome one with one male spade terminal/self grounding.Like the Oregon one? Which one?
I mean, "What brand"? They do not all work on the same units. I only recommended the Oregon one because I have used it several times on 032s, but it won't work on an 031.
And also, on some units, you have to reverse the polarity, which makes having the 2 spade terminals nice.
its for an 032 ;o)I mean, "What brand"? They do not all work on the same units. I only recommended the Oregon one because I have used it several times on 032s, but it won't work on an 031.

Check continuity from ground to the end of the spark plug wire for the secondary, should be a few thousand ohms and from ground to the input wire on the coil with the kill switch turned on. If you turn it off it will ground the primary and you get -0- ohms. It has no polarity so it doesn't matter which meter lead you use for continuity on this..
Looks like I'm gonna have to take some of my own advice. I just took in a Stihl 031AV that doesn't look too bad but doesn't have any spark. I'll start with checking the continuity of the coil, if it's okay I'll next move on to the points and see if they need cleaned and set. If that doesn't get it then I'll put a WIMA capacitor in it to replace the stock condenser. If this all fails then I'll check the wiring and maybe go with a Nova II chip.
the beauty about the one I fitted is that it screwed directly to the original mounting hole thus I only had to fit a female spade electrical connector to the original trigger wire. happy days ;o)I have also used an old module off of a Shindaiwa T25 trimmer, but that is another thread........
Well, I guess I got lucky in the ignition part anyway. Checked the points and they looked kinda rough so I got some 400 sandpaper and cleaned them up a bit. Put the flywheel back on and it has spark! Now all I need to do is find all the rest of the parts it needs. Spark plug wire, AV mounts, bar and chain and maybe a good cleanup.
They're not cheap over here either. I actually just needed one on the rear handle and I rebuilt the one on the handlebar. Turns out I didn't get it right in the running part like I thought. It indeed has spark and compression but I put a small amount of mix into the cylinder, gave it a pull and it wouldn't hit a lick. Looks to me like the timing may be off. I checked the crank key and it was intact. I'll re-check the points setting and the flywheel gap and while I'm in there I may replace the condenser and give it another whirl. I'm sure there is a modern module that will fit this saw but I haven't done any research in this area.I don't think the av mounts will be cheep? they not cheep over here in the u.k anyway.
