Default Issues starting

Hello everyone, I bought an 03 Anniversary edition sportster 1200 a few weeks back. Everything was running smooth and well for the test ride as well as taking it home. Upon taking it to work a week or two after having it I let it sit in the sun while I worked 8-10 hours. Ready to go home the bike wouldn’t start for me. The following morning at 5 am the bike fired right up at the shop. It did this once more at work, then I went for a ride and 10 minutes after riding the bike stalled while I was in fifth gear and wouldn’t start. I let it sit for 10 minutes and then got home safely on it. I have been questioning the ignition module but at now uncertain after taking a blow dryer to if for 1/2 hour and the bike remaining on. However after I turned it off this time around if failed to start up upon trying to do so. What’s the issue. How do I know for sure if it’s the module?

When you say wouldn't start is the bike turning over and not starting.Or is it not turning over?If the latter try tighting the battery cables.The rigid Sportsters can vibrate the cables loose.

Yes the bike sounds like it wants to start, for some reason it appears that the heat temperature has something to do with the bike not starting. I will try looking up how to tighten the cables on the battery anyways tomorrow. As it got hot it started running a little sluggishly and I turned off the bike because I started producing smoke from trying to heat up the bike. After that it wouldn’t start, 15-20 minutes later it started back up just fine again. I’m tempted to install this new module but would hate to waste the money if it needs to be spent on a different part.

Also thanks very much for getting back to me, as you can see I really can use a more Harley educated person insight in this. More info: 12k miles/ no receipt on 10,000 mile service which I should get done as well.

I get a feeling you're thinking it's heat but it may not be.

If it is...

Besides metal expansion...

Electrical tape slips in the heat.

......

I gotta 03 too! Love it!

Good Skill.

The reason heat is a factor is because when I came back the next morning where it sat out all night in the coolness the bike fired right up and even started later that day fine. Is the module intermittent or perhaps something else I have no idea how to check, no one has been very helpful so that’s why I come here for guidance.

Not the same bike but I just went through this on my Ultra. It would get up to temp, I'd go for a ride, stop for something, return 5 minutes later and bike wouldn't even turn over. Turned out to be the selonoid.
