Sounds good to me. Check voltage at batt and alt to confirm. May just be knackered battery not taking/maintaining charge.

If you can start it check to see what voltage you have at 2000rpm with lights and every thing on should be about 14+ volts if not sounds like alternator proberly regulator pack on back.

I believe you can, Wammers is the man in the know, he seem to know all the part no and set voltages.

Once charged...check the standing voltage after 30 minutes off charge.....battery could easily be duff.....a battery test like a shunt or drop test would better indicate condition of the battery...

Most odd faults on the Range Rover brand can be traced to weak batteries or lack of Alternator charge.

Alternator fecked or battery duff dragging Alternator output down......

More than likely duff alternator, charge should be above 14.4V engine running (debate exists on exact figure from 14.2 to 14.8V - but yours is way off and is wrong)
