speedometer not working

well as the title states the speedometer isnt working or light up. i checked the transfer case but there is no spot for the speedometer cable by the tail.
only thing on the transfer case was 4 vacume lines. question is if it doesnt light up could it electrical.

thanks again in advance
rick

the drivers side of the transfer case... in the tail shaft section is where the speedometer gear adapter is. If I can recall yours should be an electric speedometer and not have a cable.

If it doesn't have lights it could just be the light just happened to go out. They are on different wires and everything. Check and see if there is power to the sender

The lights and speedo are 2 seperate circuits and 2 different issues. X2 on the location of the VSS on the tailshaft. Check for faults. The VSS is an input to the ECU and should blow a fault if its not working.

Dose your odometer work?

When I first got my '93, both the spedo and odometer were not working. I checked the speed sensor, and traced all the wiring back to the ECU, and then up to the dash. All the wiring was fine, but what I found was a burnt out trace in the printed/ribon circuit that is behind the gauges. The burnt trace was one that supplies constant + to the gauge. I was able to get the spedo working by simply making a jumper wire and running it from the posative terminal on the tach, to the positive terminal on the spedo.

Thats another one to bookmark Muddy93. Ive never heard of that either! The ECU would still get a signal that way. What other indicators didnt function with the B+ trace open? Thats a good one to know.

Que89YJ,
In my case, the trace was burnt just before the spedo connection, so the only gauge that didn't work was the spedo/odometer. If I remember correctly, there are two ribon circuits, one for the spedo and tach, and another one for the rest of the gauges. Depending on where the brake was located though, it could effect multiple gauges, only one gauge, or all of them. It's one of those things where you'd just have to pull the gauges, and check it out, and make repairs as needed.

To check the codes using the ignition,
turn the key ON, OFF, ON, OFF, ON, and then cound the number of times that the CHECH ENGINE light flashes.

NOTE: The first time I tried to get codes this way, I couldn't get it to work. Aparantly if you go through the on, off, on, off, on sequense to fast, it will not flash the codes. Once I slowed down a bit, it flashed the codes just fine.
The light will flash, and then pause, and then flash again;
EXAMPLE, code 55 will be displayed as "flash, flash, flash, flash, flash" pause "flash, flash, flash, flash, flash". Then there will be another pause, and the next sequense of flashes will begin. I found it helpfull to write down the number of flashes, so I didn't have to try to remember them wile I looked them up online.

bust out your cell phone, use the video cam to record the flashing so you can easily record/remember how many times, and if there were any flashes.

Speedometer Not working 1994 Jeep yj

I need Help with my speedometer in my 1994 Jeep yj that has been converted to a ford 302. I bought the jeep a few months ago and have been driving withought a speedo sense. finally got around to fixing. Purchased a new speed sensor and still nothing. all wires are in place and have power to the sensor. Tried to test the new speed sensor but couldnt seem to figure out how to test. the wires have all been replaced by PO so i have no clue what wires are suppose to go were from the plug ( Solid orange, Grey with white stip, black with blue strip). I wonder if i should just go aftermarket?? any help would be GREAT!!
