Default Ignition Module Problems!!!?

Hey everyone, Im new to the site and Harleys. Just got my first bike. A 03 Sportster 883. I love it. THe weekend I bought it I rode about 300 miles.... not a single problem. Then it started to backfire every once in a while, then after it would heat up it would die. At first I thought it was bad gas (or being out of gas)... then after talking to a few people and searchin here on the forum I heard about the ignition module problems that cause this exact issue. I was wondering a few things....

First, where can I find a replacement ignition module? I heard from my mechanic that they are about $100. I looked on J&P cycles and only found ones that are more expensive and single/dual fire, programmable, etc....

Second, how hard is it to replace? Ive heard that it is very simple...

Thanks in advance everyone. I been grinding my teeth every day while my bike sits and doesnt get used.

Try to replace the relay before spending big bucks on the ign mod.

Take the ignition cover off, then look on the module for a small led. turn on key and see if the led lights up red. If no light then try to start the engine, the led should flash, if it's not flashing then module could be bad or there could be a problem with the Bank Angle sensor or a bad connection in the wiring harness.

Worked on a buddys 01 after he had negative battery cable problems, turned out it had used the ground for the ign module when the main cable went bad. Had to run a new ground wire to it to get it to run.

You can find modules on ebay for less $$ than the stealer, I got a 02 SE module for a 1200C for 40$ a couple months ago.

It's simple to replace, unplug connection, identify which color wire goes in which hole in the connector and remove all of them. Replace module then put the wires back where they belong in the connector. Set the timing of the module as the service manual says and you should be up and running.

My 01 Sportster 883 ignition module flashes when we turn the key on. So it's still good? We've replaced the coil, voltage regulator and ignition relay switch. We don't know what else to do. Don't want to buy an ignition module if not needed? Anyone know what we can check, we have a black wire that's not connected to anything off the coil has nowhere to go, or we can't find where it should go. Can't find specs for it.

Download a service manual and trouble shoot via chapter two.
