It is unfortunate that you have been unable to resolve problem but it is very difficult to follow your responses.
Maybe you are using a smart phone instead of a computer and are having difficulty in "seeing" the entire thread.
There is an unusual lack of response from other members so perhaps others are having difficulty too.
I still do not understand if the ODOMETER is recording miles as you ride or if it is just lighting up. It makes a difference.
Consider rereading the entire thread and see if you missed a response. For example:
The odometer works fine, but the needle is stuck...What does fine mean to you?
Does ODOMETER record miles as you ride down the road?
Everything looks good until I get moving and nothing...What does everything mean to you?
the new unit isn't working at all.Just lights up but doesn't do anything...what lights up?
The speedo lights up and self-tests (needle swings to 120 and back to zero), LCD lights up and shows all zeros on the odometer and trip meters...Does ODOMETER record miles as you ride down the road?
I should have specified that is the after market speedo that does the sweep. The stock one is stuck but the LCD shows the trip meters as it should and the trip switch seems to work as normal. It also behaves normally, i.e. switched between odometer and trip counters....Does ODOMETER record miles as you ride down the road?
Also, I have checked the charging system and it is charging as normal, not over voltage...What is normal to you? What are DC voltage numbers at battery posts at rest. while cranking and then high idle ?
The face is perfect, something internally is holding the stock speedo needle at seven mph. The factory unit can be opened but it is not very user serviceable...it has a small stepper motor.
Was motorcycle battery dead and someone jump started this motorcycle from a running vehicle?
Working from memory the sensor has THREE wires.
The output wire, white in this case.
The red wire battery voltage.
The black wire is a ground so it's worth checking too.
12v on the red and a good ground on black.
One of the three wires cold be damaged or the sensor itself could be bad BUT Does ODOMETER record miles as you ride down the road?
To be clearer:
If ODOMETER adds miles as you ride down the road...if odometer ADDS miles then sensor should be OK.
If ODOMETER adds miles is the addition correct for distance? You ride 0.5 miles and odometer records 0.5 miles.
Does speedometer connector have an inline speed-o-healer? calibrator? Since we do not know if you are original owner then perhaps another owner added a speedometer calibrator.

Yes, unfortunately I am on a smart phone. I haven't gotten around to buying another computer yet. I wrote down all your questions so I don't skip anything.
So, first the old stock speedo. The odometer and trip meters show milage, but are not changing anymore. The needle is stuck at seven MPH. I ordered a new speedo from J&P Cycles. It is not a Harley unit, but rather a J&P branded "stock replacement" unit.
What I meant by "everything looks good" is that the new speedo powers up and does a self test routine when you turn the key on. The unit lights up, then the needle swings from zero to 120 MPH, then back to zero, then the LCD lights up and the odometer reads all zeros, as well as the trip meters. The new speedo does not record any movement, i.e. no speed reading, and no activity on odometer or trip meters.
There are no additional modules such as a speedo correction unit, etc. that I can locate.
The voltage on the battery after pulling it of the trickle charger is 13.5v, it drops to 10 or 11v during cranking, then sits around 14.3v at high idle and never goes over 14.4v at highway speeds.
I don't think it was ever jump started, but will ask the owner. The reason I don't think he jumped it is because someone before him put a regular bolt through the fender from the bottom with a wing nut on top. When I removed it to get to the electronics under the seat, the bolt fell out and requires the rear tire to be removed to get it back in. I just don't see him doing that. I replaced it with the correct hardware.
I'm pretty sure I covered all your questions. Oh, again, no odometer activity.
Thank you for taking the time you took to respond.

Problems is very likely the speed sensor.
Either sensor is bad or wiring for sensor is bad.
At this point I would consider review of black plug for speedometer to see if there is a connection problem but most likely the speed sensor died.

Right on. Yea, connections all look good went through it pretty thoroughly. I ordered a sensor and it just got here today. It has some funky spade style connectors on it even though J&P had it listed as fitting that bike. I'll just run into town and pickup some of the right pins and reuse the stock plug housing that's on the old unit. That's what I do when I do handlebar wiring extension for new bars...
Thank you for your responses and time, I appreciate it very much!

Well, it sucks to report this. Speed sensor replaced, new speedo, nothing...
I can't find any problems with fuses or with the wiring. Does anyone know which pin on the plug at the back of the speedo is the signal wire?

By the way everyone following this thread, I rechecked all the wiring just now. All three wires from the sensor plug test perfectly for continuity, and when everything but the sensor is connected, I get good solid power and ground at the sensor plug.
One more update. I tried a second sensor today since the one I got the other day was a cheap off brand unit. The one I tried today is an S&S sensor. Unfortunately same results, still no speedo.
I am at wits end on this bike. I don't know of anything else to try or do. Anyone have any ideas?

I was totally stumped and the j&p telephone service person told me he thought the speedo was defective and to return it. Seemed like an unlikely shot in the dark! Wouldn't you f'in know it, bad speedo from the factory! Done, fixed, out of my damn hair! I thought I was losing my f#$-+ mind! I am so relieved!
