Ignitor testing?
Is there an easy way to test the stock igniters on my gls-se using a simple multi-tester or voltometer?
I got mine tested at the local Advance Auto Parts, and the guy didn't seem to know what he was doing. I'd like to see if I can confirm the igniter failure as my problem. Thanks for any help.

You need a little more than a muti meter to test the ignitors.
I was under the impression Advance could only test domestic systems. If they did have the correct adapters for a j109 and it passed I would not see any reason for further testing. If it failed, then I would bench test it myself.
I used to use the method outlined in the FSM but it gave me false readings. I have had ignitors pass the FSM test but fail me when put back in service. Then I made a bench tester using a spare dist., coil, plug wire, spark plug and a 12v source. This better duplicated its application and I could see a difference in the spark produced to the plug. The ignitor in question passed the FSM test method but when I used my new bench test, it produced a very weak spark to the plug. Put in a known working unit and it produced a strong zapping spark.
Wish I could take the credit for this testing but was a result of a search that Jeff20b had posted.

I saw that diagram in a book. I don't want to build a circuit just to test it. I posted a recording of the tach during start up. If it doesn't spike, isn't that enough to know?
What's the difference between the trailing and leading ignitor? Which one is which? I was told the trailing ignitor is the one that should be replaced. Which one is that?
I bought two ignitors years ago in anticipation of this happening someday. Do I replace both? Or do I need to replace just the leading or trailing?
Thanks for reading.

@Siraniko I'm about 45 - 60 min away (depending on traffic.) I really appreciate the offer but I have a couple used (and tested) igniters in my spare parts bin so I'm going to just start swapping out parts until the problem is solved. (I hate this way of troubleshooting!)
