Now what I'd do?

[pick]

Errghhh.............. Recently hardwired my GPS to the battery. Spliced the wires into the pigtail from the battery the feeds my Battery tender so I can unplug it whn not being used. I have also taken the wires off the bottom of my Rivco air horn to clean and make sure they had contact. This morning, bike won't start? Possibly????????????????????? left the key on in acc. mode, not sure, but thats all I can think of. Now, after a few minutes on the battery tender, starts but now my headlight modulator is out. Headlight works on both high and low but no modulation? WTF? Could I have moved a wire from it? I have NO idea as to where the modulator is or how its wired(Prevous owner installed) Anyone have any idea where to start?

I think your going to have to split the fairing to get to the light modulator..(not sure) but buy splitting the fairing you would have visability to trace the head light wiring to see where previous owner installed it.

 

Sounds like you may have left the key on in the acc position with the electrical device on that you were hooking up...

A good battery charge should fix that.

 

You can still ride it without the head light modulator, and when th ewether gets a little better I can ride mine out to Atlanta to see if I can help if you dont get it fixed by then.

 

I cant get out there next weekend cause I am having that lunch meet & eat in Millbrook, and you were going to go to Datona Fl., I thought anyway.

 

The modulator may just be a blown fuse since you were playing with wiring, you may have grounded one accidently and blew the fuse going to the modulator..

next question..where is the modulator fuse located...ha ...your guess is as good as mine...but it might be inside your front fairing..(in-line fuse).

Wellllllllllllllllllllllllllllllllllllllllll, as it turns out............................When I had the dash off to run the wires, when putting everything together again, there was this small plug, looked like a fiber cable? Hmmmmmmmm what'd that do? Soooooo I tucked it neatly under the dash, out of the way(in the dark).

Sooooooo, I go undo the dash, grab that little fiber cable, put it out into the light, and viola! modulation!!!!!!!!!!!!!

Sooo that little cable is the light sensor that ensures the modulation only occurs during daylight..............................

 

Lessons learned. LOL

Thanks for the reply though Eck, again, your johnny on the spot! Bike ran good today, gonna plug the ais on my next oil change as you told me and also replace the clutch springs right after getting back from Daytona!

Wish we could make the M&E the 23rd...........

I wondered if these were wired to the High beam that you would loose the high beam, so this answers the question. Thats pretty neat.

 

Glad you found the problem

Morning Brad, there is some debate on weather to modulate the high or low beam. I perfer the high, but there is a percentaage of folks that think modulaing the high beam distracts drivers and they won't see turn signals, etc. But at least if they see me, thats the first step? I have sen some discussion on it.

Ride safe!

Brad, just for FYI, when HD (Northwestern University)came down and put on our motor officer course, they do a demonstration of how a headlight modulator(wigwag) does wipe out certain front flashing blue lights. As anyone knows, the first thing you will see on an approaching police vehicle are the wig wags. The HD insructors demonstrate this at various distances with both regular and LED lights and after a few hundred yards, its the wigwags, not the blues that you see first. Just food for tought......................
