Good day all,

I have a 1984 FLHTC EVO stock. I have rebuilt the card already. My issues are that the bikes starts and runs fine in idle mode. But once you revv the engine it backfires thru the carb and cuts out. I am trying to test the ignition module but the manual is giving me issues.

I am at the step where is tells you to turn on the igntion switch and momentarily ground the green and black pins together and pay attention for a spark.


The two reults are as follows.


a.) Spark: Check the sensor resistance as described in this chapter? But where and excatly what sensor? and what should the resistantce be?


b.) No Spark: Check the ignition module resistance as described in the chapeter. But I have test result to look for or what pins to check it on.

So basically what I am is how do you test the ignition module, what pins what should the ohms read? Any help please.

Sorry for spelling and grammar

 

I have seen and had before a website with the data needed unable to locate now. Thanks again.

 

Hmmm, I'm thinking a used module should be an easy and cheap swap meet or eBay item as one of the first upgrades any Evo owner does is swap out for a module w/ a higher rev limit. Easiest way to test one is swap it with one you know works. Or do what I did and upgrade to a Dyna S single fire. Easy as pie to install and set up and eliminates the module altogether.
