Something weird happened this morning. Took my bike in front of the house, removed the key and saw that my speedo is still lighted up. Turned the key back and forth and prob still there. When I pulled the brake ( front or back) the speedo went off. Took the bike for a ride, everything went fine. Came back home and sahut the bike down removed the key and the speedo is still lighted up. (you can see the number on the odometer) Any idea? Thx in advance

I've seen this on my SILs 04.

I told her to bring it to the dealer when still under warranty and ask about it.

She did not.

Hasn't seemed to reoccur in a while though.

Don't have an answer.

mine did this once, only once. i think the ignition switch was stuck in run position. i wiggled key and it went out.

What's weird about this is that literally squeezing the brake lever shuts the speedo back off, and, in the case of my SILs bike, releasing it allowed the speedo to power back up.

Tuning the key on/off again, wiggling etc had no affect. In the end I wound up giving her a bungee cord to wrap around the brake lever until she brought it to the dealer to have em look at it.

It must have stopped doing it, because she never followed up.

She was even kind enough to throw away my bungee cord :rolleyes:

i would expect a problem like this on an older bike, like mine the ignition switch is begining to show its age, it used to click when i turned the ignition key, i can feel the key stops still, but the key will pull right out between the acc position and off. i was a dumbass one night left it on over night, went to leave for work found it still on the battery had just enough juice left to crank her up. hope you get it figured out.

It's almost like a relay is sticking or something.

But what's weird is how the partially depowered brake light circuit seems to affect it.

And the fact that it's no longer, in my mind, an isolated incidence.

The problem changed a little bit since this morning. Now when I remove the key the speedo is still up, but when I hit the brake the speedo goes off and stay that way. ( I had the battery disconnected for a couple hours) Anyway no bungee cord for me! I just called the local dealer and they will take my bike Friday.

Well, please let us know what happens!

Another update, when the bike sit for a while, no key in, I grab the brake the speedo come on, another grab on the brake it goes off..... go figure

heavier current draw sucking the juice up. ide need to look at the wiring diagram. not now, im drinking.

Yeah, but it didn't seem to leave a battery killing parasitic load.

And when the brake lever was hit, it DID NOT illuminate the brake light, it just seemed to shut down the speedo.


not now, im drinking.

Obviously :laugh ;)

speedo and warning lamps are led's like 5mv of draw.

sorry 5ma of draw

damn kev, now im interested. ill go get wiring diagram and see what i find.

Yup, that's about what I expected (bwaahaaha) I knew you couldn't resist. :wonderlan

Thx guys, time for me to go to work, but I will check that thread as soon as I come back

looks like orange and white wire connects from speedo to brake...why? dont know but pulls ground at highset load or getting a backfeed ground through brake switch. hope this kinda helped.

ow wire is power on, connects turn signal module, stop light switch, right turn, left turn, rear stop switch, and directly to fuse block to ignition switch.
looks to be accy fuse, not inst fuse.

sounds like sticky ignition cause that is light cicuit wire and ignition is on off and accy. off is open cicruit.

huh?

You're saying (in the earlier posts) that OW provides 12-volts to all those compoennts through ignition switch when the ignition switch is turned to the ON position.

And in this case we're getting voltage, but for some reason ONLY to the speedo backlight and LED, but not to the rest of the lights, and THAT is caused by a sticky switch?

I would have thought you'd either have 12-volts on that circuit or not, but not just have power on a small part of that circuit?

What am I missing (besides the beer ;) )

the best i can make of it is slight induced voltage carried through moisture or arch in contacts. not enought to light rest of system. honestly, not sure.

that circuit is only for lights and grounded at powerpoints. since the switch completely opens cicuit, there is no other voltage path.

Sounds potentially reasonable.

I'll call it

"Plausible"

in Mythbuster's fashion ;)

led's are very efficient. takes near nothing to light.

Ok here's what happen tonight. Before I went to work, pulling the brake shut the speedo off, let the brake go and still off, but after a little bit, I can see on the odo, a shadow of all the digits. let it go that way. Came back home for lunch, and the speedo was on (odo and backlight). So i put a zip tye on the brake lever and the speedo went off. went back to work. Just came back cut the zip tye, speedo stayed off. turned the key on and off, speedo went off. Will wait a couple hours and will check back. Electrical problem are the funniest to troubleshoot:frownthre

actually your very lucky to have a consistant problem than a sporadic problem. diagnosis is actually a lot easier when problem is actining up. personally ide remove the fuse for the lights if your gonna let the bike sit. if it is a switch thats bad arching will cause heat and posibly burn up something...

my son in laws super glide is doing that also he dropped his bike off yesterday let you know what fixes it

Gracias, looking forward to the report!

they all use the same switch...right?

try unplugging your ignition module an see if it goes out

I had my 04 try and start when I turned the key on. And if in gear would jump forward. I traced every thing and unpluged every thing and checked them . I couldget current to the mini switch for the starter so removed the start switch which is sealed checked it. seemed to work ok. Put it back togather. took a hair dryer and heated all my switches and dryed them . knock on wood no more problems. I had washed the bike a few days before at the car wash. And may of gotten moisture in switch. BUT on you problem YOU have so many milley amps like 3+ all the time evem with the switch off. AND may have a bad ground. and feeding back from brake switch. when pulled in which would kill the voltage to the spedo. It has to do a little thing when you turn switch on for the comp and spedo to do there thing. You will see a little jump on the spedo when you turn key. AND if you fire it before it does this you may get some weard stuff. mine will show all kinds of speed . on the 96 I had. Not sure but you have a bad ground some where??

Update. Checked the bike again this morning, the speedo was off. Turned the key on they off, the speedo stayed on, pulled the brake, went off but after a minute, I can see the shadow of the digits. Put a zip tye back on the brake. Can;t wait to bring it to the dealer.....

Already tried that, no joy

how about pulling fuses one at a time to eliminate circuits?

Ok just tried that, all fuses had no effects excepts the battery one (of course) found some corrosion around the contacts, cleaned them up with contact cleaner. Everything seem to be working fine but after a bit the backlight came on again. The only difference now is that if I wiggle the ignition switch back and forth, once in a while the speedo go off, but after a while come back on. I put a meter between the battery and the lugs and I'm always drawing a couple mA

you will draw 3 milley amp according to harley with every thing off for a short time till it tell it self to cut back to sleep mode. Any one try and jimmey your switch??Get some contack cleaner with the water remover and spray in it and blow dry it with a hair dryer . till warm to the touch . and then check it.

does your bike have an alarm or anything that stays powered at all times???

Another update, when the bike sit for a while, no key in, I grab the brake the speedo come on, another grab on the brake it goes off..... go figure


sounds like the lowest bidder on the ignition switch. definitely strange.

reminds me of my old ford fiesta. i would drive down the road and hit the horn, if it beeped, i had brake lights, if the horn did not beep, then i had no brakelights and had to continue to hit the horn until it did beep. then brake lights. one night, the wife and i went out to dinner, locked and then shut the door. as soon as the door shut, the electric cooling fan kicked in and the windshield wipers started going back and forth..... weird car. did not have it much longer after that :)

Can you take me to, funkytown?

I hate electrical shit like that - no thanks.
Good luck.

Start replacing stuff. Start with the brake light switch. And see if there's corrosion in the brake light assembly itself. Some wire is shorting on some other wire. You're going to have to start going through the whole system to find it.

Try and use the button behind the spedo and do the test shown in the topic for testing it then clear it the (code)AND it may solve your problem. and may show your problem code. as every thing will show a code if you know how to read it. SO check that outon testing . gar

If it stays on with all fuses out except the battery fuse, something must be leaking power from the battery circuit to the accessory circuit (which powers the speedo light and the brake light). It must only allow a small current flow... just enough to allow the low current drawing components to light up. When you hit the brake switch it tries to light the higher current drawing brake light and the "leak" can't supply enough power so the backlight goes out. It should also go out if you hit the rear brake or horn (also powered by accessory). Turn signals might make it go outtoo , but they run to the TSM which is electronic and might not draw enough to kill it.

The only component I see the 2 circuits have in common is the speedo itself and the fuse box. If everything looks good in the fusebox area and there's not corrosion inside the speedo connector, my guess is something is wrong inside the speedo.

is the turnsignal module in the same circuit?

yup. it is

Went into the diag mode and it shows "None" in all of the topic.....

just for sh@ts an giggles try unhooking the turnsignal module

Hmmmm! I think my bike know what is going on! Suppose to bring the bike to the dealer this afternoon, and the son of a gun don't show sign of the problem this morning:censor Hey Preacher, can you perform an exorcism on a 1200C 2005:eek:

any update on this?

any update on this?
Not yet suppose to get the bike back tomorrow, will keep you posted

im at the edge of my seat, not really but i am curious

I have this exact same problem on an 04 883c that I just bought. My speedo shuts off if I press the horn

Got a message from the dealer yesterday. Of course they cannot duplicate the problem. They told me that they checked the wiring and everything look fine. They told me that the only thing I can do is wait till the prob appear again and bring it back. At least the bike was not there for nothing since they rejetted it and installed my new air cleaner. The bike is ready but there's snow on the ground so I will pick it up tomorrow( suppose to be sunny and in the mid 40)

the dealer called my son in law last nite. told him they need to replace the speedo.
