Igniter testing

Does anyone have actual experience testing the igniter unit ? I have a 80 1300 that I bought as a project. Done carbs, cam chain tensioner and a ton of other stuff. It starts and runs, but not quite right yet. Has good spark on all cylinders. Going thru various things, I tested the igniter and according to the manual it fails all the out of bike tests but one. It passes the in bike tests. Pic has the results. Used 2 different meters). 

I think the note under the bottom picture explains it. Unless you are using the meter that K used (maybe analogue too) then the readings will differ. These are semiconductor components that will perhaps vary depending on the meters test voltage.

Maybe analog is the key. All those old factory testers were analog. I just ordered one. We'll see ?

Performing electronic tests without an understanding of what you are testing and comparing the results to a "standard" is not easy. When you find that your test specs are out of whack, what does that mean?
So I'll tell you that inside the igniter there are 3 Darlington transistors which are high current transistors (electronic on / off switches. The small connector receives input from the pulser coils and switches those Darlingtons on / off. What you are testing at the small connector relates to the "Base" , "emitter" and "collector in the Darlintons.
Here's a Youtube video  Testing a Darlinton transistor  and the guy explains the various tests and what the meter readings mean.
Basically, you have Darlingtons that don't test out and a new igniter is in order, judging by your results but it's nice to understand why the test indicates a failure..

Well.... while I am certainly not an electronics expert by any means, I can follow instructions in the fsm. I guess my real question is, has anyone actually, personally put a multi-meter to an igniter and what were the results ? By the tests from the manual, the igniter is bad, but the bike runs, has spark all cylinders. Is this possible ? Could that be a cause of weak / intermittent spark ?  it seems to idle ok, but trying to rev it, it randomly spits / backfires thru the carbs, but once past a certain point, say 2500 rpm it revs fine and doesn't miss out. Thanks !

I have used a meter (digital) on an igniter and was only concerned that I got similar readings on each of the three circuits under test. I am usually more concerned with minimum spark gap (should be more than 7mm) between the ends of each coil output pair - using a spark gap tester
