I read a couple of the threads but didn't see an exact match so thought I'd put the question to the group. Following a stop for gas after riding 30 minutes or so, my speedometer's needle started jumping between the actual speed I was traveling (at least it looked close) and zero. As the bike got warmed up, the speedometer settled at zero. I followed the HD repair manual procedure for removing the speed sensor and cleaned it. I did find some grime and some shavings and cleaned the sensor thoroughly with a rag (no chemicals). Put it back together and the speedo again registered for about 30 seconds, then started its dance and quickly dropped to zero.
Ironically, the turn signal canceler seems to be not working or at least sluggish and the gas gauge began its little dance around 3/4 full. Wonder if I am looking at something electrical and more general. Any ideas on what to check next? Any way to rule out the speedo itself before investing in the speed sensor for naught? The bike has 35k on it.
thanks in advance,
Blue

Blue, I don't remember all the details. Someone more knowledgeable than I will hopefully add to this. But the speedo impacts more than just the happy little needle we see informing us how fast we're going down the road.
Barring diagnostic gear that might (or might not) tell you specifically what the problem is your next course of action is the old tried and true try-the-simplest/cheapest-thing-first approach. Make sure all the connections are clean and tight. Then replace the sensor. When all that's left is the speedo.. well.... gulp $$$.

I had this same problem along with the turn signal problem, and it totally cleared up after I REPLACED the speed sensor. Sometimes those electrical gremlins don't like to get cleaned. If I remember, the part was not that expensive, but the HD dealership did not tuck the cable all of the way back in and I had to basically do it myself. Hope this helps. Scot

For about the same price as the Harley branded part (74437-96) the aftermarket has one that's got a shiny billet end on it too.

had same issues at around 25000 miles..replaced speed sensor and fixed problems

I had a similar problem on my Road King and it turned out to be the ignition switch. I was able to jiggle the switch when it occured and make it work. Replaced it and had no further problems.

My complaint was exactly the same on my 03 Softail (88B Motor), new speed sensor fixed it. :2vrolijk_21:

Thanks Cash338, Twolanerider, Screem, IslandUltra & Hobo for the feedback. Based on the sage advice here I purchased the speed sensor (my cruise is out also) so all the symptoms pointed to the speed sensor.
Scot, I have no doubt that the dealer didn't route the cable correctly. That is the problem I am having this morning. The service manual is not very descriptive about this installation, but when I got into it, I found that the sensor cable was neatly run through a loom clip (?) at the front of the bottom of the battery box with two other wires and also clipped to the frame (in front of the right side cover) with other wires. I got it free okay (after taking out the battery) but now I can't seem to pull the cable out for lack of room (starter, etc.). I can cut one end off and slide it out, but that doesn't help me get the new cable in. Scot or others who have done this replacement, what's the trick (so cussin' at it hasn't helped :-[)...
thanks,
Blue

The easy way to install is to de-pin the 3 pin connector and pull wire from under the starter. De-Pin the new one slide wire under starter and apply pins to connector.

Brad,
Thanks but flustration won out while I was waiting for an answer I cut the old one (at the sensor) and slide the old one out - as I knew it had to come out anyway. The new part number 74429-97C (original was 74429-97) doesn't want to go down the last bit (beyond the o-ring I'm guessing). I will just have to be more persausive ::). The service manual shows the cable routed under the front of the chrome starter cap and behind the oil spout and it does tuck nice in there and I was able to fish the other end (without de-pinning it up through the frame in front of the battery box. I will need to replace the wire loop that I cut that attaches to the frame to re-secure the wires. As Scot suggested, I doubt the mechanics at the dealer will be this careful so beware if you have this part installed. I don't think heat will be a problem where I am installing it, but if someone knows better, please advise.
thanks,
Blue

You did pretty much exactly what I did. It almost seems they put the connectors on after the wire was run through... :nixweiss:
-
Thanks Scot. I appreciated Brad's suggestion and the routing of the wire made the best sense but the de-pinning was a little too involved for me. Mine went back together pretty simply with my (our) approach, I just need an off-set wire tie to snug up the cable, the wire loom and what ever the other cable is that were wire tied and plugged into the frame rail.
Raining cats and dogs here so no test ride yet 8). Thanks everyone for the help and suggestions.

DITTO!

hay blue, did the sensor fix the problem? if not what year is the bike. it makes a difference in the sensor connecting to the speedo first or the ecm first, let us know.

Axil, Hobo and the rest of the gang, thanks for all the help. Replacing of the speed sensor did in fact fix the problem :orange:. Test drove it just now and it was great to have the speedo, blinker canx and cruise back. It was the combination of these symptoms that made me confident that the speed sensor was the culprit.
As I said earlier in the thread, the service manual is not very descriptive or helpful on the removal/install. For me I had to take the battery out, cut off one end of the old sensor to remove it and reroute it a bit differently than the original.
Scot also made the point that the dealer didn't tuck the wires in appropriately on his and he had to work on it himself. There would appear be a lot of room for a dealer to do a sloppy job on this one if they are "in a hurry" so beware. Last but not least, I asked the speed sensor and the parts guy first pulled a cam sensor which looks somewhat similar (on the sensor end) so make sure you are getting the right part - 74429-97C on my bike.
thanks again to all,
Blue

glad to here it's ok now, when people route the wires thy have to think about viberation. happy motoring
-
Axil,
Agreed. Cash indicated that he'd done pretty much what I did with no problem, plus there was a wire tie that plugged into the frame on the rail close to the sensor itself to snug things up plus the one attached where the original was - in front of the battery, so I think I have it covered. But thanks for the reminder.

Hey Blue, your thread here cast bad juju on my red SEEG. I got about 10 miles out from the hotel in York, PA on the way home yesterday and the speedo needle danced back and forth between 0 and 70-ish a few times then died completely. Never to awaken again. Had the tach. Had the GPS with its own speed display on the handlebar. So really didn't give a rat's ass. But it would've been nice to have cruise control for the 1150+ miles on home. Geez I'm a wimp... :huepfenlol2:
Oh well. Will replace it this week. Just means the odometer is short by that many more miles. The instrument itself was replaced under warranty when the bike had about 12K on it. The replacement came in at 0 miles rather than actual. Now another 1000 or so short here. Many more part failure and the red bike will be a reconstituted virgin all over again.

Twolanerider,
Sorry for the slow response. Started a new job and haven't been getting to my normal fun stuff much. Sorry to hear about your SEEG's speedo doing the hoky poky...I'm with you..not having the speedo is not as bad as losing the cruise, blinker canx, etc.. Hope you were able to get er' taken care of. em Sounds like you've had more than your share of electrical glemlins... I feel pretty lucky. Haven't had too many problems and am at 36k.
Ride safe,
Blue

On our way home from our little trip, Jamey's bike lost speedo, odometer, brake lights. Replaced two or three fuses (why they all go at once is a mystery) and all working right again.
At least for now. No Bad JuJu please. :-*
