Have a 2003 kenworth t600 and rpm voltage battery, speedometer, and odometer not workin and dash lights keep going off and on... What could it be?

SOURCE: 95 Ford Explorer Odometer

I have the same problem, however there is no cable on my model. There is a small motor inside the cluster which drives the gears for the odometer, the worm gear on mine broke (cracked into pieces, cheap junk). Probably have to go to a junk yard to get the speed/tach cluster.

SOURCE: started out with headlights out then the speedometer, odometer, gas gauge, oil, battery, rpm's are not working, fixed the headlight was a fuse but other stuff still won't work.

sounds like your missing a ground somewhere.

SOURCE: Speedometer, Odometer, Trip Odometer stopped working

yes the transmission speed sensor has most likely failed, to confirm this have a trouble code test run

SOURCE: 98 expedition battery light comes on with increase of rpm

There may be no loss of voltage, but is there a surge of voltage?

As for the battery itself when tested, it should read 12-12.5Volts across the
leads when the car is off. When the car is running, the battery should be reading 13-14Volts across the leads, anything lower means the alternator is not charging your battery, anything higher means the alternator is over charging and damaging your battery.

Another cause for the battery light could be your ECU has detected an error

Testimonial: "thanks, haven't seen a alternator discharge light go on and off, normally it's either worked or didn't"

SOURCE: speedometer, gas gauge, odometer, rpm gauge not working

My gas guage, speed odometer and tempiture does not work
The speed odometre is reading 9999999 what should i do
