Ive got a 99 disco II that has run great with no problems since I got it. This afternoon I get in (lights come on), put key in the ignition and turn one click (wipers and everything works fine), try to start and lose all electric. Lights go out, no wipers, no horn, nothing. What could it be?

 

Dead battery, loose battery cable...

 

Exactly what he said. Before my battery died there was no warning. Got in my truck, turned key, and nothing.

Check your battery.

 

Ya was the negative battery cable, I hate when that happens. This is our first Rover, and with all the security alarm stuff in it, thats wha I had figured it might be.
