Afternoon from Colorado,

My usually extremely bulletproof reliable XX is giving me headaches, maybe some one can lend some ideas. (I think she's pissed because her younger Suzuki roadracer sister has been getting more attention of late)

I did my normal spring tear down, clean up and fork rebuild this year. I did change the low beam bulb, as it had croaked last season. I put her upper faring back on, tested the new bulb. It worked brilliantly (Pun intended) and so did the bright bulb.

After completely putting the faring back on, I noticed that one of my turn signal bulbs was not glowing when the power was on. I did turn on when I turned on the signal on that side. Weird, but I was in such a rush to get riding that I blew it off.

20 miles later, I found that now both the signal lights work fine, but both headlights don't function. They are plugged in, the bulbs are both fine, the fuse is fine and I'm at a loss.

I'm wondering if I maybe pinched a connector when I re-assembled the faring.

The part that kills me is I live in Winter Park (Read- still winter here) and the XX is at a friends house in Denver (80 miles) where the weather is a bit milder. So I'm trying to gather ideas to try when I return to her, which should be later this week.

Help?

Help?

I vote main connector between Frame (bike) and upper fairing.

Check your Regulator/Rectifier. Put a multi-meter across the battery, start the bike up and see what voltage you get. At about 2k revs, the battery should charge up to about 15V and then settle back down to around 14V. If it doesn' the reg/rect unit is screwed.

I had the same symptoms as you (blown headlamp bulbs - note, they may not look blown, but believe me they are) and my reg/rect was feeding 20V back into the battery. It is a common problem.

Reg/rect changed (about £70 from "Jaws"), no more blown bulbs, no more cooked battery and a happy me.

Hope this helps.

This may be off target a bit, but, as I recall, the '99s and '00 bikes had documented electrical problems caused by corrosion in the main harness connector. I am not sure if the gremlins associated with the problem included lighting issues but it is worth a look at a wiring diagram.

Dodd · 04-29-2008, 11:12 PM

I saw a previous post about that, the connector under the seat? I'll try the r/r and given the results I'll take her down and clean all the connectors.
I can't help but think that I did something when I put the faring on I bunked something up. I've never had any problems with this bike.

freddyg · 04-30-2008, 8:53 AM

Dodd, I doubt it's something that you've done. I will put money on it being the reg/rect that's at fault.

Toynut does have a point about the loom problem though. It is also documented on this site here. What these guys also say is that even if you don't have the loom problem, it's worth doing "the fix" anyway.

Dodd · 05-01-2008, 6:24 PM

Well I think the R/R is ok, I'm not getting any voltage to either of the headlight plugs, and the bulbs are ok (I tested them with an outside 12v source)

Guess I'll try cleaning the plug thing. Man this sucks. My bird is down, my race bike's right side slider snapped off and broke the engine mount bolt in half, and today I broke a hardened steel extractor trying to remove it. Now I'm going to have to drop the engine to get at the head boss to see if I can get that thing out! AHHGGGH! Why are the motorcycle gods so angry at me?

Dodd · 05-01-2008, 8:36 PM

Ok, there is no power at the light plugs, at the main plug or at the fuse block. The rest of the fuse block has power, so I'm at a loss. Help please! I know there has to be some reasonable explanation?

Nutter67 · 05-02-2008, 7:15 AM

Have you checked the switch - power coming into and going out of?

I'm looking at the wiring diagram in my Haynes book and it looks like if the speedo, tach, turn signals, horn and starter are working, you should have power at the fuse for the headlights as they are all feed from the same feed.

Sound to me like the socket in the fuse panel for the headlight fuse is not making good contact. Try pulling the headlight fuse and check the power supply side on the fuse panel. It may take some probing to get a reading.

If still no power then something is wrong with the fuse box which seems unlikely but I guess it could happen...

Dodd · 05-03-2008, 11:02 PM

I checked and there is no power at the block for the light fuse, but power everywhere else.

I broke down and went to a honda shop and picked the brains of one of the techs. He has been wrenching on hondas for 20 some odd years.

I told him what I had, what I had checked, the ideas all you fine folks came up with and he told me, "The switch". (High low switch)

So I'll take it apart and clean it, and report back

If you have no power on either side on the headlight fuse you can stop right there. The dimmer switch, (high, Low beam), is feed from that fuse thru the starter switch no less.

You can try making a jumper wire, preferable with a fuse, and check the circuit by coming straight off the + terminal of the battery and going to the headlight curcuit side of the headlight fuse slot in the fuse box. This should power up the cucuit and if there are no problems with any of the switches, the headlights should work.....

If you don't have the manual for your bike, here is the link:
http://www.cbrxx.com/attachments/hon...ice_manual.pdf

THese things have all the wiring diagrams needed to troubleshoot a problem like this and are an invaluable resource as is the site...

Good luck!

Dodd · 05-05-2008, 6:26 PM

OK I was mistaken about power at the fuse block, I wasn't probing enough. I used the jumper wire trick, and everything except the headlights powered up. This also happens when I turn on the key, indicating there is power where its supposed to be. I guess the next step is the headlight switch. Can anyone tell me how to test that?

jsfrv6 · 05-05-2008, 10:20 PM

Pull apart the connector by the dimmer switch and with the key on check for voltage on the blue wire with white strips from the harness. If you have voltage there it's probably going to be the main harness connector, the proverbial Achilles heel for that year.
Here the link to that fix:
1999-2000 Honda CBR 1100XX FI Light Fix

If no voltage there, then it's going to be the start switch as the the power for the blue/white wire goes thru it first.

As far as the dimmer switch goes it is used to activate the high beam only and the dims should work even if you unplugged it.

For what its worth, at the main harness connector the blue wire white strip is Low Beam, Blue wire black strip is High beam...

Good luck..

Dodd · 05-05-2008, 10:22 PM

No power at the dimmer. Maybe the relay is bad?

jsfrv6 · 05-06-2008, 9:16 AM

The power comes from the fuse block, black wire red stripe, thru the start switch, thats the push button switch, out of that switch, blue wire white stripe to the low beam and the dimmer.

Pull the connector apart at the start button switch and check for voltage on the black / red wire coming from fuse block. Also check for continuity between the black/red wire and the blue/white wire coming out of the switch. You should have continuity until you push the button.

When you have the connector apart get your jumper and put some voltage on the blue wire white stripe on the harness side which should power the headlights.

sv61 · 05-06-2008, 10:58 AM

I have this issue intermittently.

On occasion, when starting the bike, the starter switch must be "jiggled" in order for the headlights to work. I have driven MILES without realizing that my headlights weren't working.

Could it be the starter switch possibly driving you crazy? Again, on my XX, I have to push lightly on the starter button (while the bike is running) ALMOST or BARELY engaging the starter, and the lights will come on.

As a point of reference, there are occasions that my bird will not power up at all (have seen a friend's VFR do this as well) almost acting like the kill switch is engaged. Sometimes turning the kill switch off and on will correct the problem, while other times, a key off and back on might correct it.

Dodd · 05-06-2008, 11:34 AM

Ok a week later and several new holes in the drywall of my garage (From flying tools) I think I've figgured it out.

I took out the headlight relay and tested the load side of the plug with my volt meter and with the key on, got 12. I then jumped the load side of the plug and the lights came on. So I'm pretty sure its the relay. I've got another one on order ($38.00, thanks Honda)

I'll post up when the part comes in to confirm if that was infact the problem. Now, does anyone know where I can get some of the little plastic faring push button connector thinggys (Big red wants EFFIN' $3.30 A PIECE for them)?

Thanks for all your help fellas, I take for granite my Honda always working, but I can tell you after this week I was ready to get another Suzuki.

Check to see if both the high and low beams come on when you jump that relay because it is only for the high beam.

If you DO NOT have power at the blue wire white stripe at the dimmer switch connector then the starter switch or its connector are suspect. The dimmer switch is used to pull in the headlight relay for hi-beam and uses the power from the low beam cucuit, blue wire white stripe, to do so.

I would say that if you only had problems with the hi-beam then the relay may be it but if your low beam is not working I would look elsewhere. According to the schematic the low beam would work even if the headlight relay is unplugged as it is only for the hi-beam.

The reason the starter switch is in the loop is so it can turn off the headlights during starting to ensure full votage is being used for the starter.

My money is on the start switch or its connector....

Dodd · 05-06-2008, 1:42 PM

And the starter switch is the one on the handle bar? Jesus, anyone wanna buy a XX?

Lol Thanks, I'll check it after work.

Dodd

Dodd · 05-06-2008, 1:57 PM

Let me clarify that, i realize the starter switch is on the handlebar, I just want to make sure there isn't another switch somewhere else.

I didn't have time to check the lowbeam but will and post.

And that is why I brought up the starter issue.

If everything is back together, start the bike, and see if moving the starter switch will make the headlights work intermittently. It sure sounds like something more concrete than just the starter switch making intermittent contact.

Well you guys are right again. With the relay jumped only the bottom light works, the bright indicator is on and the dimmer switch doesn't do anything. (The bright indicator stays on and the bottom light stays on aswell regardless of where the dimmer switch is)

So it looks like the starter switch, because as earlier stated there is no power to the blue/ wht. wire on the dimmer side. As for the starter I tried bumping it, wiggling, etc. but nothing changes. Is it possible to clean the contacts or will I have to buy a new switch? I haven't dug into it yet.

You can check that switch if you have a mutimeter. Pull the connector apart and check for continuity across the black wire red stripe and blue wire white stripe coming from the switch. Also while you have the plug apart you can jump across the black wire red stripe and blue wire white on the harness side and turn on the key and the headlight system should work...This would verify the start switch is the problem....As far as taking it apart and cleaning it, I'm not sure but if it's broke what the hell, give it a try!

Dodd · 05-07-2008, 12:07 AM

Well I pulled the switch apart, found one of the contacts had a good deal of schmutz on it. Cleaned it, and the light (Bright) worked. It was still spotty on a test run, it would flicker a bit under hard acceleration, but it worked. I'm sure if I tore the entire switch apart and cleaned it all, or replaced it it would solve the problem. Initally the FI light would flicker, and the signal would cause a ghost light in the FI aswell. I'm hoping that its not that damn plug referenced earlier. It settled a bit after a hard wheelie landing.

I really appreciate all of your help. But the bike is now in the garage and I'm going to have some cold beer. I'll worry about it later.

Thanks again.

(The bright indicator stays on and the bottom light stays on aswell regardless of where the dimmer switch is) So it looks like the starter switch, because as earlier stated there is no power to the blue/ wht. wire on the dimmer side. As for the starter I tried bumping it, wiggling, etc. but nothing changes. Is it possible to clean the contacts or will I have to buy a new switch? I haven't dug into it yet.

Cleaned it, and the light (Bright) worked. It was still spotty on a test run, it would flicker a bit under hard acceleration, but it worked. I'm sure if I tore the entire switch apart and cleaned it all, or replaced it it would solve the problem. Initally the FI light would flicker, and the signal would cause a ghost light in the FI aswell. I'm hoping that its not that damn plug referenced earlier. It settled a bit after a hard wheelie landing. I really appreciate all of your help. But the bike is now in the garage and I'm going to have some cold beer. I'll worry about it later. Thanks again.
