You could try disconnecting the battery, charging it then re-connecting it. They don't like jump starts or low volts.

You have actually traded power for unreliability,welcometo the mad world of Land Rover.

Just diss the negative. Battery should hold at least 12.8 volts after it comes off charge, if not it's duff. Worth also checking the alternator is charging after you re connect the battery. With the engine at 2000rpm you should see 14.4 volts give or take a couple of tenths at the battery.

Range Rovers are so comfortable so you don't get a sore arse waiting for the AA!
