94 International speedo/tach not working

Hey there, I hate to revive an old post like this but the .pdf wiring diagram you put on here would really help me out. I tried to dowload it but it wouldnt work. Would you be able to send it to me? Thanks. BW

 

I re-uploaded it in your other post. Hopefully it works, if not, let me know and I'll try something else.

 

Have a question about an 89 International 2574 speedometer. Doesn't work. Found the sensor on the tail shaft has 2 wires. Cant find the 2 wires coming to it. If I pull out the dash and the speedometer has 2 wires could I just connect to those and run 2 new wires ? I'm new here and it wont let me start a conversation with you. That's why I posted on here. Thanks for any info.

 

Yes, the two wires from the speedo sensor can be rerun straight to the speedo module GREEN connector on pins 5 and 8. Polarity shouldn't matter.

 

Tank you for the info. I've found 4 wires coming down that direction, hooked them up in about every order and still nothing. Thinking maybe it is the sensor. Thanks for the information !

 

Would you know where I could find a diagram for the 89 mod. int. 2574 ?

 

Hey guys. I'm new to the forums/site but I've spent a lot of time on here in the past month. I have a 95 International 9300 with these issues. The speedometer bounces once started and then settles around 15-25mph. While I'm driving the speedometer tracks accurately. My odometer is also tracking like I'm driving even when I'm not, so it is racking up "miles" for no reason. I just had the ECM flashed and I replaced the speed sensor on the transmission. I'm not sure what else to do. Anyone have any suggestions?

 

Really sloppy loose trans output yoke will cause this. make sure it is tight and not vibrating to cause a false signal.

 

I looked at the transmission yoke and drive shaft and everything is securely mounted. I will occasionally hear 3 beeps and the check engine light will flash but then turn off. I've read this is a DTC but when I plug in I don't see it on the scanner.
I guess the only thing left is wiring from the speed sensor or speedometer/odometer relay?

 

3 beeps is when the cluster is getting gauge data that is out of range or incorrect. The gauge with the bad data should also point to six o'clock. Sometimes the fault is too quick for the needle to move, but the alarm will sound. Not all gauge faults will trigger a fault code in the engine. 95 is a tricky year. You could have an electronic engine with either an electrical speedo gauge or electronic speedo gauge. Both look the same to you. The electrical speedo sends the speed signal straight to the cluster and electronic sends it to the engine and then the engine sends it to the gauge by datalink. I think electronic gauges will sweep at key on, and electrical ones just twitch a bit. You need to know what you have there before you start running wires.
