bad ground or bad sensor or a short
A failed instrument cluster.
not directly... The tach gets its signal from the crankshaft sensor. the signal is processed by the computer where it determains spark timing, fuel ratio and other things. information is relayed via wires to the back of your insterment pannel, and are converted into readable units on your tach. Same with the odometer, it gets its signal from the computer via speed sensor. being you lost both functions on your pannel, i would suspect a faulty cluster.
check the fuse panel
It depends on whether or not the car has a digital readout. If it has a digital display, chances are it would be a wiring problem, somewhere right behind the odometer. If it has an analog display, since the spedometer still works, chances are the odometer itself (the display) has gone bad--like a little gear in there or something. This is one of the simplest odometer problems to fix; just replace the display piece. If the spedometer wasn't working it would be a whole different story--probably a faulty cable.
It should work. I have a 94 w/o a tach and put a LE version cluster with tach in. Works fine. There should still be a tach wire grouped into the harness plugs. Just unplug your old one and plug in the new one that's it.
most likely the electricity going to them
If the speedometer works but the odometer does not, the odometer has failed.
why would a speedometer and odometer not work on a suzuki motorcycle?
It should work ok if the wire for the tach under the hood is connected and I don't remember which one it is.
The odometer is broken and needs replaced.
My speedometer works and the odometer does not because there is a plastic gear in the odometer that is broken.
Tach is driven by a motor signal, speedo is from the trans the sensor is bad on the transmission
