Hey folks,

I just installed a set of LED driving lights on my 05 burg 650. They look really good however I wish they operated as well as they look. Issue being that as soon as I fire up the engine the lights flicker. The faster I rev the engine the more they flicker. The lights act as if they are running on an AC current. That said... I'm wondering if need to install a bridge rectifier between the power source and the lights.

It makes the lights flicker. ;)
You don't always get a good connection. The bikes DC is a pretty well-filtered supply so an extra bridge is redundant.

The ground to frame is solid and making excellent connection. What I called a flicker is more of a pulse. The lights burn nice and steady untill I fire up the engine. Once started the lights pulse as if drawing current from only one side of the stator. However I'm drawing power from the low beam feed.

Every circuit on a Burgman has a return ground wire. No chassis grounding. The engine is rubber mounted and as it vibrates it moves. This may cause a pulsing open ground

There is a group of black with white strip wires factory banded together and the plug end has a cap over it. I'm assuming being black they are system grounds. Do you think that would work as well as tying to the battery neg.??

Being "old school" everything grounded to the frame. I never considered that I might be dealing with an isolated system. THANKS for steering me in the proper direction.

Yes, I think all those Black/white wires are a common ground pickup point.

We need to send him to the other Washington on the East Coast
and have him do some re-wiring.

As the bretheren say run a neg from the battery to the headstock and link to that

Well.... The bundle of black w/ white wires with the covered socket was actually a junction point for the system ground. I was able to make a "plug" to tap into that covered female socket and forego splicing into the harness. No more strobe lights.... HOORAY!!!!
