Help: Quick fuse question...
2009 Street Bob here. I have the service manual which lists the fuses 1-15.
I changed the rear brake and sigs to LED over the winter. all worked fine in garage and then I took it for a ride and the rear lights went out. Likely from a crossed wire that blew a fuse.
Well I checked the wiring and found the problem. So I go to replace the fuse and figure it is the one labeled "lights" in thr manual. No change. All other lights work and the front sigs are lit up but the rear is still blank. Any suggestikns would be appreciated.
I am just hoping it is a different fuse. Lol

Not sure which is the fuse but a simple way to test all of them quickly is with the bike on - probe both poles of each fuse with a test light - the one that fails to light both sides will be the bad one. The rear lights wont light up unless the signals are on - they are not running lights like the front.

If you have front sigs but not rear it is not a fuse problem, you have a wiring problem or a lamp problem.
Remove the LEDs and see if they work straight off a battery, if they do the problem is most likely a wire on the bike.

Did you use a kit to put the LEDs in? As I recall LEDs don't have enough resistance to work properly so there needs to be something added to the circuit to compensate. If you just picked up some LEDs and wired them in I think you're going to have problems.

True, but they will flash faster.

Isn't there a fuse for the tssm? (turn signal module)
Did you check the wiring on the underside of the fender? If your tire chewed it up, that will cause a short and blow the fuse.
also, did you install a load balancer? You need that for l.e.d lighting.

Wiring is all fine. no tears or breaks. Worked for a few days and then went out. All of the rear lights at the same time.
The brake is LED with a load equalizer. The signals does not need a load equalizer from what i have been told because I did not change the front sigs.
Thanks for the suggestions. I will try to hook the wires to a battery and see what happens.
Any other suggestions welcomed.

Even if you have one for rear turns you need one for front turns if they are all LED, I discovered this on my own ride when I recently changed my front to LED as well as rear.

You were mis-informed, if the turns are LED you need them to have a load equalizer. The one for the running/brake should also have connections for the turns.
Even if you have one for rear turns you need one for front turns if they are all LED, I discovered this on my own ride when I recently changed my front to LED as well as rear.

No he isn't, on the newer models (not sure of the cutoff) as long as either the front or rear remains incandescent then you don't need a LE. Here is a video of my Kellermann single LED running with no LE.
