Battery Draining in a matter of hours.

[cjp79]

Anybody got any ideas what could be draining the battery when the car is left???

Its a new battery, the alternator seems to be charging fine. If the car is left for more than a few hours the battery is dead.

There must be a big load from something but I can't find out what.

I have checked the drains mentioned on other posts (boot space light, alarm horn etc) but it doesn't seem to be them.

Can anybody think of anything else that it could be or any ideas how I can track down the electrical fault?

The Car is a UK RHD 996 C4

2001

Manual

Many thanks again for your help.

First if your battery is over 4 or 5 years old - replace it as it likely no longer taking a charge.

If you are positive your battery is good then you need to put an amp meter inline with the battery. Then remove fuses one at a time until you find the fuse circuit that is drawing all of the power. Normally a 996 draws about 40-60ma (as I recall).

Once you find the circuit where the drain is then it should be fairly easy to trace down the component.
