Any help you or advice you guys can give would be awesome. heres the deal... 2002 FXST. bought it brand new in june of 2002 somewhere around august of 2002 the speedo started acting crazy, would go to 120 mph when i was doing like 30, would go to bottom center of the speedo and get stuck. everything else worked just fine. Never really worried too much about it really.

fast forward to this year, did a major facelift on the bike and converted to a heritage /deluxe type . while I was at it, i decide to try and remedy the faulty speedo, so I bought an aftermarket speedo and a new speed sensor. Now, when I turn on the ignition, the speedo needle sweeps all the way to 120 mph then settles back to 0 ( i know this is the normal procedure when starting) then does not budge at all after that. the backlight and the odometer read out function but reads 00000. I have tried to get into the diagnostics and clear any codes, however, when I attempt to do this, the readout does not change from 00000.

 

ok, I went out today cleaned all the ground contacts and checked the voltage at the battery. At idle I have around 13.4 dcv at around 2000 rpm i get around 14.4-14.8 dcv it fluctuated a bit.

 

what does the tip of your old speed sensor look like?

also are you following the correct diagnostic code retrieval procedure for your bike? They are not all the same..

checked your ground at the battery and the frame for looseness and or corrosion?

checked your + at the battery for looseness and or corrosion?

 

here is the 00 - 03 procedure (originally posted by glider)

1. Remove right side saddlebag and side cover if so equipped. Remove protective plug from data link connector. Other models will be under the seat.

2. To activate the diagnostic feature,follow these steps.
a. Create diagnostic test wire or use a female spade clip which will bridge the two terminals perfectly.
b. Install diagnostic test wire/clip across Terminals 1 and 2 on the data link connector, they are marked.
c. Turn Ignition/Light Key Switch to IGNITION and wait approximately 10 seconds (4 seconds lamp ON, 6 seconds lamp OFF) for check engine lamp to start flashing.

3. All trouble codes are sent out as a series of flashes. To retrieve the first digit of the trouble code simply observe the number of times the lamp flashes.
a. The lamp will then flash one or more times to indicate the first digit of the trouble code.
b. The length of time the lamp is illuminated and the length of time in which it is off are each about 0.5 second in duration.

4. The second digit follows:
a. Following the transmission of the first digit, there is a 1.2 second pause in which the lamp is off.
b. The lamp will then flash one or more times to indicate the second digit of the trouble code. Count the number of times the lamp flashes to retrieve the second digit.

5. If more than one trouble code is sent:
a. Following transmission of the second digit of the first code, there is a 3 second pause in which the lamp is off.
b. Once all codes have been sent, the data string is repeated. When you have recorded the same trouble code twice, it is an indication that the transmission has been restarted and that all trouble codes have been retrieved.

IMPORTANT NOTE ..If diagnostic test wire is installed across Pins 1 and 2 on connector in lieu of a Scanalyzer, the ECM is placed in a diagnostic test mode and the engine will start. The test wire must be removed from the data connector and the ignition switch turned OFF or the check engine lamp will continue to flash codes. A historic trouble code resides in the memory of the ECM until the code is cleared by use of the Scanalyzer or a total of 50 trips has elapsed. A trip consists of a start and run cycle, the run cycle lasting at least 30 seconds. After the 50 trip retention period, the trouble code is automatically erased from memory (that is, assuming no subsequent faults of the same type are detected in that period). The numbers after the 'historic' or 'current' is the speedo code number, but without the electrical diagnostics manual you're not going to know what they mean.

If it matters the bike is a carb bike, not efi. I was under the impression that holding the odometer reset button in while turning on the ignition with the run/stop switch in the run position would enter the diagnostics and the codes would appear on the odometer.

Yes, I did check the grounds and the battery connections, I actually cleaned all of the connections at the battery and frame.

 

I'm pretty sure what I posted above is correct procedure for your softail.

 

ok cool. Thanks alot. I will give this a try.

 

OK, so I went out today and made the test wire, bridged the two pins as instructed. The check engine light flashed very quickly, I tried to count them, What I got was a range of 11-14 , to fast to count then a slight pause then 11-14 again. It continued to repeat that same sequence as long as I left the ignition on. I left it on for 10 minutes and it was still doing the same sequence.
