Coil is probably fine. I would GUESS your problem was the pickup or the ignition module itself or the wiring between. There are some resistance tests on the pickup in the shop manual. Is this an aftermarket ignition system or stock?

Not sure on the ignition system, I just bought the bike about a month ago, previous owner only had it for a couple of years and didnt do much too it. What should I be looking for other than the coil to tell if its stock or aftermarket?

I will look at the shop manual for testing the ign pickup.....

The ignition module will say "Harley Davidson" or "Screaming Eagle" on it, or something else. Not sure where it is on a soft tail. Regardless, the manual has a really thorough diagnostic section for "no spark." Go through it all and if you find something out of spec, that's likely it. Otherwise, we can throw parts at it until it works, but it's cheaper to find the problem first.

And that is why we all say to get the official factory shop manual.

OK, I cant get the Harley manual downloaded and my Clymer manual doesnt show any tests for the ignition module or the pickup. If you had to take a guess on which to replace would it be the module or pickup? Anyone.....anyone......

I would buy the official shop manual. It will save you money on this job alone. If I was to GUESS, I would GUESS first the pickup, then the ignition module, as that seems to be the order they tend to fail in. Here's the pages from my official shop manual, so you can see the advantages of having one.

Without the test adapter, get creative with pins, nails, paperclips, alligator leads, etc. You just need the circuit connected and be able to measure what's going on with the voltages in the lines. Of course, don't short anything out.

Did you ever do any thermal dynamics testing? Have you tried the "wiggle, shake, tap" test on wires/connectors/components?
