Here is the story. I picked up the cycle vision eliminator tail light around December 2016 so its been on the bike for roughly 2 months. This last weekend my brother noticed my left side tail light would randomly turn off then back on. Today on my way to work i noticed my left turn signal dash indicator was flickering almost my entire ride to work (30ish miles). No idea what was happening at the back of the bike but i reached up and put my hand over the front signal and everything seemed fine.

As i started using my signals (specifically the left one) I had the red key light come on and stay on for probably 2-3 minutes. When i got to work i looked the bike over, didn't see anything out of ordinary.

On my lunch i plugged in my laptop (Thundermax) to check for any trouble codes, everything came back fine. I went for a 25ish minute ride, didn't have the issue happen.

On my way home, things got worse. Indicator on the dash was flickering the entire time. At times when using the left signal i would get a rapid flashing and the red key light on the dash would light up.

I had my wife follow me in her car and she said the left side of the tail light looked to have been flickering at a rapid rate. I imagine it was the same rate i saw on the dash.

Now whats interesting is this doesn't happen at idle. And usually doesn't happen at a low speed (about 30mph). Once i give it some throttle, left indicator on dash starts going nuts. Also worth noting, the turn signal appears to be working just fine (left and right) while this is happening.

I just went out and found a way to (kind of) to reproduce the issue. All I did was put the bike in gear. Once I do this, the left side light goes out and comes back, simultaneously the left indicator on the dash flickers. I believe this is whats happening while i'm on the highway, just at a much faster pace.


Key take aways here:

• Left turn signal indicate ON DASH is flickering
• The left side of the tail light is also flickering
• The rapid turn signal only happened briefly and was ONLY the left side (NEVER happened on the right side!)
• Load equalizer is installed (provided by CV, big and yellow. Not the small black one that comes with the kit. This is what they said to use.)

I emailed them earlier today when i got to work, no response. I'm going to try and call tomorrow morning. If anyone has any ideas on this though i'd love to hear it.

P.S. I unplugged everything and plugged back in to ensure no loose wires. I even swapped out the yellow (bigger) load equalizer for the smaller black one. Issue persists.

 

Sounds like you could have a load equalizer that is going bad. I would definitely get in touch with CV and tell them to replace it. Can you by-pass the equalizer, we know your sigs will flash faster because the bike thinks they are out, but you should be able to tell if the issue is still happening when the equalizer is not a factor.

 

I don't know how the wiring works for your setup, so it is probably a dumb suggestion, but could the ground for that left rear signal have worked loose so that it isn't getting a good ground, or do all of the lighting elements ground together?


Or perhaps the insulator on the "hot" wire for that turn signal may have somehow worn through so that it is shorting?

Since you tried swapping out the load equalizers, the only other thing I could think of would be the eliminator itself has developed a fault.


Good luck, let us know what you find!
