Edited... posts crossed!

You could be on the bottom 200 scale for that for a more accurate figure in the 32-38 region.

How about black/yellow to black white? Still on 200 scale. Looking for between 31-37.

BTW your 132 in the first test is perfect.

The reading in post #13 might be more accurate on the 200 scale?

So might the reading in post #14.

Ok, I'll try again tomorrow, as you can tell from the pics I'm loosing light now

Thanks for sharing your knowledge though, I will be a happy man if I can get this diagnosed and fixed, even if the part is expensive it's saving labour costs and much more satisfying to investigate the problem personally

No problem. Get those update readings tomorrow and we'll go from there.

Should mention if resistances check out OK the cranking speed voltage tests would be informative.

Sadly a budget meter will not correctly show the readings from electronic ign systems due to the very short voltage peaks. You either need a very expensive meter or a DVA/Peak voltage adaptor.

Here is the problem getting a steady reason shown on a quad...




Here is how to make the adaptor if you have a friend in electronics...

And my final bit of the night... a pretty good video of a guy working right through ign tests which might give some ideas...



Different outboard but same basic principles.
