QuestionThank you very much! This is really helpful cause I could not find the draw at stand-by. I just want to make sure that its has to be .05 Amp?? With or without alarm activated ?? Because mine is much much more, around 0.8 - 0.9 A alarmed and around .6 -.7 disalarmed. If that is true then I have the problems with my electronic.
Thanks for warning about disconnecting batter while car is running, I didn't know you cant do that?? What may happen??
Thank you very much for your time.

-----Question-----
Hello John!
I'm having some problem with my Discovery 2001, petrol 4.0.
My first question my explain my other. What is consuming energy (current) in the LR on a stand-by mode, armed (stock alarm).
Here is the problem:
About month ago on the morning my battery completely died. First I was thinking that i left something on so I charge it , it work for couple of days and then one morning died again. It happened 3 times before i decided to change for a new battery. I bought a new battery, put it in and guess what two days later same problem. I jump start the car drove to work (about 20 mi) and back. next morning same problem. I checked the alternator -- it works, giving 14 V. I was even trying to disconnect the battery while engine running -- works great.
I pretty much know a lot about electrician since i work as a industrial mechanic, but this is driving me crazy...
Please help if you can.
Thank you.

Never unhook the battery while your vehicle is running - the electrical transients can do thousands of $$ in damage.
With the truck off, unhook the bettery and connect an ammeter in series with the battery lead. Measure the draw. A normal vehicle has a draw of about 0.050 amp at rest.
Your is probably higher.
Start pulling fuses until you find the circuit that is causing the draw, then test those circuits. If none of the fused circuits have a draw look to the alternator and non-fused items.
There is no quick answer. it's a step by step process.
Answer0.05 is your target number.
Let me put that in perspective with more explanation. Let's say your battery has a 70 amp/hour rating. That means it can supply 70 amps for one hour and it will be 90% depleted.
So that means it could supply 7 amps for ten hours and be 90% dead.
Or it could supply 0.7 amps for 100 hours and be 90% dead.
and that is the situation you face.
Hope that helps. Give us a good rating on the feedback page if you find our advice useful.
