Toylander Electrical Problems

Well as some of you may have read in the Freelander section ive got an ongoing problem on my Td4.......Im in need of some help now as im about to pull all my hair out with it.

It appears that I have a short on one of the circuits, as the battery fails to charge when connected to the vehicle, but will charge fully when on the bench unit. Even a long run fails to charge the battery, with something draining it down over night to the point where the central locking wont work, and the clock re-sets.

Ive been out this morning with the test meters and have checked the two cables coming of the positive terminal. The feed to the auxilery box is drawing a total of 8.5amps, with the ignition off. The second cable down into the engine bay is drawing 0.5amps when the ignition is off.

This leads me to think i have a short on one of the pre-ignition auxilery circuits....but from there I'm lost...has anyone else had experiance of this or similary problem? or can anyone offer any help before i got mad?

My biggest worry is im off to Ireland in 3 weeks on holiday and could do with this being fixed ! [-o<

Id start with seeing how much current it is drawing when the ignition is on? and when the engine is running? see what the alternator is doing too.
alternator may be at least part of the problem.
But i have heard of freelanders needing total dash's rewiring... but it could be a simple problem still.

piggysteve:
Joe I once had asimilar problem which was a faulty cigar lighter, took the bit that gets hot out job cured. Have you tried unplugging the alternator to see if it's draining through that.
Electrical problems can be swines to trace can't they

thermidorthelobster:
This thread was slightly disappointing;  I was hoping to find out just how the electrics could go wrong on a Toylander (not a Freelander).

Sharpshooter:
Silly question. But is the alternator charging? How many miles has it done? We are assuming the alternator is ok. As when the diode pack goes, this causes a dead short, and you normally find your battery flat in the morning.

I would be worried that anything is drawing amps with the ignition off. Other than the radio and clock.

All i can suggest, is connect up your ammeter as you have already. Remove the fuses and relays of the high demand items. Ie wipers lights and such. But be careful not to remove abs or airbag fuses. As this often leaves you needing a reset. Do it one at a time, and see if removing one of them alters the current draw.

Im affraid with electrics its mainly a process of illimination. If you were closer i woiuld say pop it round. :)
