Strange speedo issue [message #785942] Mon, 17 July 2006 22:03
Greg B  
Greetings and have a beer from eh bar, or two, okay, three but no more
than that unless you need one.

I have a strange issue with my speedo, and was wondering if anyone else
has had this issue. I've looked in the service Manual and haven'
t been able to pinpoint the issue.

Here's what happens. At idle the speedo and odomoter (odo) work fine,
but when the rpm's are raised it goes in and out. Both the speedo and odo.

I can be running down the road and it will say i'm going 10, 35, or 0
mph whatever, the odo is off and engine light is on. If i pull in the
clutch, within a few seconds i achieve accurate readings until; i
release the clutch.

Sometimes it will start working normally, and when it does that, it will
work for the duration of that particular run. If I shud the bike off
for gas, a beer what have you, it may or may not work properly after that.

Its strange, but I figured someone here had this issue. Remember it
always works if I pull the clutch in and coast for a few seconds at speed.

I have changed the speed sensor device and it did not solve the problem
so i returned that part.

TIA
GB and you should have had plenty of beer by now! :)

That would have been my first guess. I had one go bad a few months ago.
I would check the wiring in the speedo circuit or could be as simple as a
bad ground.

You don't happen to be having any issues with the cruise control do you?
My speedo and odo went nuts when my CC was out of adjustment. Doubt
that's your issue though, but figured I'd throw it out there.

Ok gota gives ya a lil more info here. On my bike - 01RK - there's a
small screw just behind and to the right of the oil refill. Unscrwew
and it will allow a boot like part up - that's what needs to be
cleaned. Had the same thing happened last year and a dealer wrench sed
"save da bucks and do dat"

Sure did. Fixed it myself!

I performed the CC's "cable lash initialization routine" as outlined in
the service manual.

Understand this is purely a push-button routine (press and hold CC
switch's resume button, turn ignition to on within 3-seconds, etc.,
etc.).

That--so far so good--cured all of my CC issues. I believe the problem
occurred because of my tendency to roll off the throttle in order to
disengage cruise. It's a compulsive-neurotic thang about not wanting to
light-up the brake lights just to disengage CC.

I believe the maxi-fuse incident occurred because I kept playing with CC
so much the stepper motor just went nuts.

Naturally, I could be wrong.

Had a simular problem with my sporty. Turned out I wasn't leaving the
ignition on long enough for the on board computer to complete its
diagnostics before starting the bike.

My first thought too, except he said he already changed the speed
sensor.

I have added a speedo-sensor cleaning to my 5k maintenance list. That
magnetic pickup can sure accumulate a lot of metal shavings. More so
than the magnetic drain plug on my bike anywho. The new o-ring is less
than a buck, so I replace it too.


The OP's problem is probably a pinched wire, or as someone else said,
he's not waiting for the computer to reset before starting up.

Well, the subject line *does* say it's a "speedo issue." I guess if he's
gonna be wearing a Speedo, his crack should definitely be clean... ;-)

I dont think its the computer not getting going before i do. The bke's
got 45k miles on it and I've been staring it the same way all the long.
I'll take an extra notice today and see, but I'm pretty confident
thats not the issue.

That issue crops up on my FXDX occasionally. The tach is accurate but
the speedo measures about 20% low. It does seem to happen when I don't
wait for the engine light to go out before starting it. Turning off
the ignition at a red light and waiting for the light to go out before
restarting it always cures it. Lately I've been leaving it 20% low
when I even notice it thinking my odometer will rack up fewer miles
that way.

I had a similar problem on my 97 wide glide. My tach and speedo got
erratic at speed. I found my connector from the stator to the volt
regulator had been loose and vibrating. By the time I realized what had
been going on the connector had arced so badly that the contacts in the
connector were shot.
You'll find the connector at the front of your engine case. Follow the
wires back from your voltage regulator and pop th econnector off for a
quick inspection.

I didn't see any on the way in or on the way home. But it was raining
and I rarely see any other bikes then. Except that nutty guy on the
sportbike that I meet on the way home. We always wave at each other. He
probably refers to me as that nutty Harley rider. <g>

Thank Dog you cleared that up! I was literally sitting her doing a

Check also the main ground bolt that the negative of the battery goes
to (as well as most of the main harness grounds) under the front of the
seat.

First of all, a bit more info is usually helpful. For
example, what year and model bike is the least I like to get to make
some sort of diagnostics out of thin air.

Either way, sounds like it's vibration related, which points
to a bad contact somewhere. If it happens to be an XL (and even if it
isn't), check the battery cables. A loose or broken cable will often
cause exactly the above. On pre-04 XLs, in particular, the battery
cables tend to break (I've found the positive at the starter to break
the most often, but they can break anywhere) and have the rubber boot
be the only thing maintaining the contact. Rev the bike up more, it
vibrates more, the contact opens and closes quickly. Sometimes not
enough to cause a running issue, but enough to affect the instruments.

If those aren't the culprit, go over all grounds, check
contacts in the instrument cluster. If it's a new bike with the J1850
serial bus, that wire is suspect as well, since it carries both the
speedo and tach signal. Also, on those newer bikes, the tach signal
comes off the speedo, so a defective speedo (or power issue to it)
would affect both. Once again, what year and model?

You found a dealership willing to take back an electrical
part? They are either foolish, or you are lucky (or you know them
well).
