Have a Disco II 2001. Alternator replaced 3 months ago, battery replaced 3 weeks ago.

On Friday Jan 2, manually turn on alarm system.
Sat. Jan 3, my son turned off alarm, and when he try to turn car on, the alarm went off.

Could not turn off alarm, manually turned alarm off. Eventually it did turn off.
Battery was drained, gave it a boost, but did not use car.

Sun. Jan 3, around 3PM went to use Landy, but did not turn on, battery drained.

Monday Jan 4. Had battery charged at Autozone, clean all connectors. Car turn on, and it did 2 hours later (but did not drive it). 4 hour later it did not turn on. Had a load test on battery and alternator at Autozone - passed.

The negative cable is a bit loose, will order one tomorrow.

If after replacing the negative cable the problem persist, how can I go about testing what is draining the battery? Read a post from Urban Panzer about putting an amp meter in line with battery cable and then pulling fuses until meters goes to zero...

Can someone shed a bit more light on this procedure... thanks.

 

Replaced the negative cable ($80 bucks for a cable)... battery still draining after 90 minutes ... your help greatly appreciated.

 

WOW, was that a dealer negative battery cable?

 

yeap, from landrover... could not find it online... and what sucks is that I still have the problem, will troubleshoot tomorrow by pulling one fuse at a time.
