I just bought a 97 Range rover, and a couple things i cant figure out, the speedo and rpm dont work, the display says ' slow : 35mph max ' or somthing like that, and im not sure what lights are on the dash above the radio, but they are all on and i cant turn them off, anyone know whats wrong? cause i have noo idea

oh yeah and theres a light on the dash of the car with a arrow pointing up underneath it

 

You probably should down load the RAVE manual set, it contains repair and owners manuals for your model.

The message is displayed when there is an air suspension fault - don't drive over 35 until you repair or adjust this using the manual. Control of the vehicle could be compromised. Your road speed is too great for ride height.

The up arrow is a fault indicator for the suspension:

Air suspension - AMBER.

Illuminates as a bulb check when
the starter switch is turned on
and remains illuminated until two seconds
after the engine has started.
In addition, the light will illuminate whilst
driving whenever ’High’ or ’Extended’ ride
heights are selected, and also if a fault with

the air suspension system is detected.


For your other two instruments, which are run by fuse #1 (10 amp):

Speedometer

The signal to activate the gauge is originated at the
ABS wheel sensors, transmitted to the ABS ECU
(Z108) which then puts out a usable signal to the
Instrument Cluster (Z142) of 8000 pulses per mile or
4972 pulses per kilometer. The signal is also
transmitted to other ECU’s, such as the Engine
Control Module (ECM) (Z132) and the Cruise Control
ECU (Z121).

Tachometer

The tachometer will display the engine speed in
R.P.M. It will derive the engine speed from the
engine speed pulse train transmitted from the Engine
Control Module (ECM) (Z132).
The pulse rate for petrol engines will be 4 pulses per
engine revolution.

The pulse rate for diesel engines will be 3 pulses per

 

There are many things that could cause these issues. I would first start by testing the health of your battery and alternator, they can cause some weird issues if they are not providing the rover with enough power. I would check your grounds for corrosion as well.

If everything tests fine, it could be your instrument cluster, or worse, the becm. The instrument cluster is easy to take out and used ones are pretty cheap. Just be careful when you swap it out with another. If the rover that you pulled the cluster from has more miles than yours, the becm will sync with it and display the donor rovers mileage.

BTW, does your rover still have EAS? Most GEMs rovers are converted these days.
