Is there a test for ignition module?

Post by Russ »

Does anybody know a test for ignition modules? My Sportster won''t rev above a fast idle and I've exhausted all the causes I can think of. Only thing I can think of is the module but I want to be 100% sure before coughing up a couple of hundred for a new one.

Anyone got a test that doesn't require workshop space at NASA?

Yes go to this thread and build one of these.

Use your ignition module instead of the Hei one used here.

All the parts can be bought from radio shack for under 20$

SELF INTRODUCTION: I was on the last board as bonustoolkit. I have changed that to my given name.
I started a project build there " File and Fit." I paln to continue that when I go back home in Dec. 2011. I first joined the board when Gary W had it in the year 2005. That was the time I really gained an interest in building chops. I have a long way to go, compared to some here.

Would you like a few pages for troubleshooting the ignition system for a '96 Buell. Includes the module in the diagram and write up.

Thanks for the offer but I've got the problem sorted out now. Much appreciated though.

SELF INTRODUCTION: Hi Dan, thanks for your time and energy spent on this new board. I hope you will give me a waiver on the email account, I have used gmail so long I don't have a clue what my service provider account is.
I just returned home from a 2 week trip in New Mexico, have a few good pix, can't wait to share my off-highway traveling. Got to put 1400 miles on the scoot.

No. In the end it was quicker to strip every system off the the loom until only the igniton module was a possibility. Not as big a job as it sounds becuase my Sportster's loom is pretty minimal. I've got a Dyna programmable ignition module on order at the moment. Harley no longer make the module for '93 Sportsters (which is a bit rich when you consider the mileage they get out of the 'back in the day' vibe). The Dyna set up sits in the nose cone on the cam cover and does away with the external module, so less clutter and less wires to hide. All very nice but I could have done without the expense this close to X-mas. Still I should be back on the road in a week or two so I can't complain.

I might ask my son if he'd build me one of those testers though, he at uni doing engineering at the moment and I've got a birthday coming up.

Be Lucky

Thanks...

FYI, on my 91 FXR, I had probems with the coils wires vibrating next to the coils and work hardening. That caused cracking,
which gradually became worse and worse, causing at first an intermittent miss, which worsened. Was a bitch (for me) to troubleshoot.
When I found it, I shortened the wires and wrapped them to the coil with electrical tape. That left a long distance for the wire to move.
I guess the tight connection at the terminal didn't allow enough movement.

93 Sportster is likely similar.
