Was riding the bike to work today and I flipped my brights on and my headlight and running lights (front and rear) went out.

I checked all my fuses and none of them are blown so I have no idea what to do at this point.

Any ideas??

 

recheck your fuse.

I've checked every fuse twice. I even replaced each one individually with a new fuse just to make sure.

 

Ok, things just got a little more weird....

So I tore the fairing apart to make sure there weren't any loose connections or pinched wires. Didn't see anything at all that jumped out at me.

Unplugged the light and the running lights were still dead. Was getting late so I said screw it, plugged the bike into the battery tender and went to bed.

Got up today and went back to work on it, plugged the head light back and and IT WORKED!

Took a 45 minute round trip into town and it worked the whole time.

Get home, pull in the driveway, turn the bike off, leave it sit for 5 minutes and go back to try and.... NO LIGHTS!

Something that I did notice was that my voltage gauge was reading between 14 and 15 volts. I'm not sure what it was before, because I've never paid that much attention to it.

 

Normally, I would say: high beam switch. Common problem. When mine went, the high beam would work, but the low beam and passing lamps wouldn't. All other lights on the bike worked fine too.

But that last post of yours makes it kind of weird. Guess it could be the high beam switch still. Contacts may be messed up inside it.

 

if you have 14

take it in for warranty service

if you have a 13 or earlier, the common part of the electrical system that would kill all your lights- like in the first post- is a fuse or relay ( many models have a fuse for the headlamp, and another fuse for the other lights.
there may also be a relay for all lights depending on year/model - this relay is mounted on the fuse block)

if you have voltage measured at the battery will a real voltmeter above 14.8 volts DC at any time, your voltage regulator is bad.

do not ride the bike until fixed or 12 volt rated parts on the bike will blow up = $$$$

Switches on my left grip went south on me. I don't remember what was not functioning, maybe turn signal. HD warranted out the repair, even before I purchased ESP. I suspect the cause may have been the pressure washer I was using.

Pressure washers are a no, no . . .

Generally when a circuit works, doesn't work, works some more the problem is in the switch, particularly if the problem is in the high beam / low beam option.

 

Just some clarification:

-This is a 2008 Street Glide
-Just over 10k miles
-Original Battery
-No fog/running lights (I am talking about the running light mode on the front turn signals and rear brake light).
