Electrical fault?
Discussion
Hey as some of you may know weve got a 1996 2.5 dt which basically is a heap of sh*t lol,
Anyway every since we got it we've had this problem and have tryed almost everything
The battery just keeps going flat, we've had 2 new alternators and 3 new batterys, they work fine for about 1 month then they just start going flat, we have to keep a booster pack with us and use it almost everytime we need to start it.
weve had it connected to the diognostic computer and no problems show up, and we've had a resistor chip fitted to the plug (apparently this is meant to solve it) weve even had to switch the interior lights off.
Anybody got any ideas?

Draw a diagram of the fuse box, which values in which places etc, then pull them all out.
Get an ammeter which can show a reasonable number of amps, perhaps 20A. Put it between the battery +ve terminal and the red lead to the car. You should see 0 Amps.
If not, you have a current leakage before the fuse box. Try unplugging the alternator or anything that doesn't go through the fuse box.
Now start putting fuses in. The only 2 things which normally take power in a car when switched off are the clock and the alarm (if fitted). When you add a fuse, you'll suddenly get a reading on the ammeter.
A battery has 10's of amp-hours so it'll be a big value, perhaps heated rear window or something (do Landrovers have such luxuries?). If it's a 60 A/H battery and the ammeter's saying 60mA (0.06A) then it would take 1000 hours to flatten the battery.
If you get all the fuses in, and still a low reading on the ammeter, call an exorcist, or look for squirrels with jump-leads.

My point is, looking at the ammeter you can see the current being drawn. If it's 1 Amp, then a 60A/H battery should last 60 hours etc etc.
I can't think of any reason why a car should take more than 0.1A.
So unplug stuff until the problem goes away.
If it's not taking more than 0.1A, look for current-thieving squirrels etc.
