If it is the same internally as the 1989 J body, I can look at my spare (I scored a nearly new cluster so kept the old faded one for spare parts).

 

Hi BIll,
If yours has the two semi-circle round pins in the back of the instrument cluster (like the picture below) that attach to the red and gray round plugs on your LeBaron, it is the same.

If it is the same, and if you have the speedometer taken apart from the instrument cluster could you tell me how the stepper motor sits on the circuit board. Flush or is there a gap?

I'm thinking I disturbed or bent the stepper motor's 3 connection pins and they are not touching the motor winding properly OR I'm shorting the stepper motor by the pin(s) touching the side silver casing and not the copper winding.

If you do not have the speedometer apart, since you are an electronics wiz, do you know how I can test a stepper motor out of the car?
Thanks for looking.

 

I have it in the spare cluster, which is similar, the warning light section is raised a bit but not in the car. As far as testing, I believe you can use an extra distance sensor and a drill while providing 12V to the appropriate pin on the speedometer.

The three pins on the speedometer, are top to bottom, distance sensor input, ignition feed, ground. From what I remember each pulse of the sensor converts to a step of the motor. I will try to pull mine out from where it is sitting and get you some pictures.

 

Did you watch the video, maybe something will jog your memory.

4374151 is the speedo for the 1987 J,G models. Daytona and Lebaron

I have 6 used ones and 6 NOS

if yours is beyond repair the NOS one will take care of that

will send you a PM

 

Thanks Jan for sharing the video. I had watched it last month but missed an important step. I watched it again, and missed the part where he said "DO NOT REMOVE THE STEPPER MOTOR OFF THE CURCUIT BOARD" to get to the gear. My Big mistake which caused the problem. I did take it off when reinstalling, messed up and bent one of the 3 pins going into the motor (picture above). I just have to resolder and straighen the pins on the circuit board and if I align it perfectly into the motor it should work. I did test the stepper motor off the circuit board and it works. By appliying alternating +12V and -12V to the copper winding in the motor turns the center shaft. I just need to align the stepper motor properly onto the circuiit board pins to get it to work. I guess I'll do it by Trial and Error. This is a lot of fun to figure out by experimenting. Thank you Bill and Jan for all your advice.

Thank you also Marty for reaching out, you are always very helpful. Let me see how I do and if I need anything I will reach out.

My son and I are learning a lot about the Chrysler G body and becoming a Turbo Dodge guru like you all, we are just late to the party. Seems everyone goes thru the common weak points of the 2.2.L T2 engine: headgasket, power steering leaks, starter, fuel injectors and coolant leaks. The car is registered, running great and now for fixing the final two items: odometer and radio.

 

I have your pictures, I removed the circuit board with the motor casing attached.

Not too hard, just takes a bit longer.

 

Thanks Bill,
Did you add solder to the three pins that connect to the motor on the circuit board? Yours has more solder than mine. Hence why one of the pins fell out of mine when I tightened the motor onto my circuit board. I'll try to align the three pins but it is very difficult to have all three aligned and touching the windings in the motor while not touching the casing.

 

I didn't touch the board other than to remove and reinstall it. it works perfectly, but I scored an almost unused cluster as mine was giving me a fit with bad connections (tach would work when it felt like it), I kept looking for the Lucas label.

 

Finally fixed the speedometer/odometer. Got an old rusty 1989 LeBaron junk yard instrument cluster for cheap, it had a good circuit board and odometer motor, except of course for the disintegrated blue gears. I compared my 1987 circuit board to the 1989 one and the 1989's odometer motor is glued onto the circuit board. My 1987 was not glued and that is why it came apart. Previously trying to fix it I overtightened the screws and bent the pins on the motor that turns the odometer/speedometer gears. It is impossible to reattach it and have the 3 pins aligned properly without shorting or making all three have good contact with the motor winding. After transferring the new circuit board onto my original instrument cluster the speedo and odometer worked. Made sure to calibrate the speedometer needle with my GPS speed and now it all works great. Onto the final repair project fixing the Chrysler Radio. Apparently my 1987 Shelby has the one called Chrysler "Ultimate Sound System" predecessor to Infinity with a functional cassette player. It sounds great when it works, but the radio and display goes in and out depending on the temperature outside.

In Summary: when taking the speedometer/odometer apart for 1987 model year Daytona and Le Barons the odometer motor is not securely installed onto the circuit board. Make sure not to remove the motor off from the circuit board or it may never go on correctly and make good contact. For the 88 and 89 model year they are glued onto the circuit board, so this is not an issue for those years.
