Speedo And Mileage Not Working

<< < (2/3) > >>

benbenukuk:
it's a 1989 and the indercators work fine but the hazzards don't.  Ben

I wouldn't put money on it but I'm going to guess it's the electronic one then.

IIRC the ignition feed to the instruments feeds the rev counter, speedo and fuel/temp guages.  So does anything work?

I don't remember offhand but I think the ignition light might also be on the same feed :?

Anyway, it's possible the speedo has failed but first you should check that all the inputs are as they should be, that it's earthed, it has power and the road speed signal is working.

You can check it using a meter, if you turn the roadwheels slowly then the input should alternate between 0 and 12 volts a couple of times per rev, you need one wheel on each axle up in the air though.  (As I said earlier, if the cruise is working then the road speed signal is present, either way you should then check it's getting to the speedo itself.)

If you need any details let me know and I'll dig out some books, though TBH if you get the speedo in your hands you should be able to figure out what's going on.

The oil temp, rev counter ect works all that doesn't is the speedo the milage counter and the milage thing under the counter that you can push the botton in to reset it, thanks.  Ben

Range Rover Blues:
Ah, speedo, tripmeter and odometer.  Sounds like a break in the road speed signal cable then.

Not trying to take over the thread or anything... but what's your sugggestion for a 1993 LSE where everything works but the trip reset button doesn't reset the trip?
