battery/rev counter problem

Hi

I have an intermittent problem with the rev counter and battery light on a disco 96. The battery light comes on and the rev counter goes dead for about 10 to 15 minutes and then suddenly alls well and working as normal.
Any suggestions?

Loose electrical connections at the rear of the alternator may be,

is there not a relay that controls the ignition? all you need to do to check if the alternator is charging is to get a volt meter and test the voltage of your battery with ignition off and then check the voltage of the battery with the engine running.you should see the voltage go from 12v to around 14v.

Hi guys, just picked up my first Landrover Discovery yesterday, (300 Tdi )
Came home 130 miles no problem. Then batt light came on & rev counter stopped working. A friend of mine who is a mechnic says Alternator is US, is he right ?
All the connections on the back of the alternator seem to be clean & tight, but don't want to go to the expense of a new one, if the problem could be elsewere.
Any advise greatly appreciated
Shaun.
