This is going to be a little long but thought I would post in as an FYI in the event someone else runs into this.
A couple weeks back I inquired on a code that weas being stored in the speedo and tach mode of the DTC on my bike. They were both storing a code of B1006, (accessory line over voltage, instruments) although I was not experiencing any issues; I thought I would take it in since it is still under warranty to investigate. This code was determined sort of by the way when I had it in for service for an ABS light on. The ABS issue was resolved with a wire repair and was petty straightforward. Upon determination of the above code, the tech spent some time checking the accessory line which was fine. I had nothing attached to it either. He did find that the little ground that clips at the steering head was a little loose and corrected that. He spent some time talking to the folks at HD tech service and they had him order and replace the tach and speedo, thinking a voltage issue might have occurred and caused something with the gauges. I brought it back when the gauges came in and had them swapped out. Code returned. I couldn’t leave it at the time so took it and rode it for a few weeks. I decided that since it was still under warranty for another month or two, I would get it back in. “dawg” was kind enough to supply me with the diagnostic tree which indicated it may be related to a charging issue. After some additional diagnostic time, the dealer replaced the voltage regulator, the stator and a security system module. Called me and told me it was ready to go. When I got there, I thought I would check to see if the code was in fact gone and guess what?, still there. They/we were stumped. I lost some faith at this point due to them telling me it was ready only to find out the code was still stored. I was concerned that this was going to turn into a nightmare. While discussing what to do next, I had a thought. A year ago, I installed a Custom Dynamics LED board in my tail light along with 4 of their LED turn signal clusters, a load equalizer and the run, turn, brake module from the Moco. For the hell of it, I suggested that they pull that out and install stock bulbs. (By the way I offered to take the bike home and remove it and bring it back,) but they offered to keep it and see it through. By pulling the LED stuff off, the code was cleared and stayed gone. I think we found the source. Now, since I haven’t experienced any issues in the year that I had these components installed, I put them back on and checked for the code, sure enough it came back. I’ll likely leave the stuff on since there is no apparent issue and since I am extremely happy with the light output and visibility of the LED setup. I sort of feel a little bad about the time invested, but they did indicate that they saw an intermittent continuity to ground, hence their decision to replace the regulator and stator. This scenario may be unique to my bike or combination but thought I’d share in hopes to save someone time if they ever go down this path.

 

Glad ya got it figg'rd out. Which load equalizer were you running?

 

I got the one that they supply. I think it's made by the same folks that make the LED boards. Street Magic Cycle Products.

Hey, I also did the ABS download while I had it in there. I didn't many miles on yet but seems to be less jittery over a rough surface upon braking. Hopefully it will be dry out tomorrow, I'd like to get out and put it through the paces to see the difference.

 

Mine is less jumpy as well since the download. I wonder if you tried a different load equalizer I'm thinking the code wouldn't come back

 

I think you're correct. I was looking over the Badlands version and am thinking I should get the Gen III since I have the alarm system. I'll Probably get one coming Monday.

 

And thats why I don't go the the stealers. Around here they are just parts changers, not machanics. I take mine to an Indy, and he will honor the warrenty.

 

Just a quick update on my situation. I drove up to Custom Dynamics and plugged in a new "signal stabiliser"equalizer module. Same codes appeared, replaced their version with a Badlands generation III equalizer, same codes. I think it's safe to say the the equalizers are showing something outside the range that the ecm is looking for and storing codes. Alarm system is unaffected and nothing notable acting out of the ordinary with the turn signals or anything else. Lights look great and visibility is 10 fold. Me thinks I'm living with a couple of stored codes......

 

Have you cleared the codes and they return or are they just historic codes?

 

I clear em' & they come back. B1006 under the speedo and tach modes.
