Power draining from battery (Fixed)

<< < (3/3)

BigA:
4 hours later, wont start again...... fresh charged battery on and turns over straight away.

I have tested with another meter and the drain is showing as 28.8 Ma ????

I think a can of petrol and a match is in need  :x

weeone:
Sounds like the imobiliser is pooched.
(that's the black spider with a dozen black wires coming out of it....)

I know it can be hauled out & slung in the nettles.... but I've no idea which wires to what :(

Disco Matt:
Land Rover sell a proper bypass dongle for the alarm spider, I forget the part number but it's worth just buying the proper part, less than the cost of a couple of pints and makes life so much simpler!

Mine had a similar infuriating battery drain a while ago which turned out to be a duff alternator, it wasn't charging the engine when running and it was draining the battery overnight.

BigA:
OK, after much flaffing about, turned out to be the alternator after all. Only found this out after i thought i had found the problem with the cable from the alternator to the battery, and plugged all back together. went out after about 8 hours and battery flat again. Disconnected alternator lead from alternator to test again in morning and the alternator was nice and warm.

New alternator now and all OK.

Still reading the same amp drain from the battery, which was low anyway, but all seems ok now.

Cheers for all help.
