Hi Guys,
I've got a 2001 Disco and I fired it up a little while ago and the tachometer did not work. All the other gauges seem to be working fine. I drove it about 5 miles and it never started to work. Tapped on the dash and still nothing. Any ideas?
Thanks.

 

You can use a $70 Ultra Gauge to display rpm, coolant temp, and other things. Driven by ECU thru OBDII port. ECU also drives tach signal in a D2. D1 gets that drive from alternator.

 

If I switch out the ecu will I need to switch the instrument cluster too, so the milage will match? I do have parts vehicle with both.
Thanks
