Driving lights

Postby zvacman » Mon Jun 14, 2010 6:14 am



The driving lights on my bike only work when the engine is really warmed up. I'm guessing a possible ground issue. Where does the main ground from the battery go? The PO had it on the long bolt that connects the two triangle frame braces together, between the brace and the engine. The engine is aluminum and probably not the best ground. Any help would be appreciated.

Thanks, Z

That's the correct place for the battery ground. I have a separate ground for my accessories that I ran from a spade lug on the battery - you might want to consider doing the same for your lights.

So until the engine warms up and expands I won't have sufficient ground for my accesories? The stereo and other things work fine, it's just the lights.

The driving lights are not OEM, they've been added by you or a previous owner. So I'd check to see what they're using as a ground, and start from there.

They are frame grounded through the mounting stud. Like I said when the engine was warm they worked fine. I think I might install a grounding block from the battery inside the fairing and ground all lights and accy's to it. The PO's favorite two things were wire cutters and tape, what a mess!

Thanks, Z

If the lights don't work until its warmed up, and you don't have problems with any other accessories, then I doubt it's a ground issue, unless there is either corrosion at the mounting points, or a failing ground wire inside the lights - but the fact that both of them are failing at the same time says to me it's not ground - it's power. Check the power wire leading to them, and more importantly, check the fuse through which they are fused.
