Porsche 968 battery drain

[bazhart]

Hi,

My neighbour has a beautiful late 968 Tiptronic which I am trying to help with. His battery drains over about 24 hours and there is a permanent 3 amp drain that we cannot find the cause for. Checked all lights (under bonnet and glove box etc). Cannot even find where the siren is to see if the alarm system is taking the drain - but the alarm fuse does not isolate it.

It must be well over 20 years ago that I last worked on a 968 (and then probably pre-airbag models) and we always used to get in an alarm expert back then when there were issues - so I am not the best person to help.

Any ideas or recommendations for anyone that might be more familiar with it in the North West Bolton area?

Thanks guys,

Baz

I had a similar problem with a ‘94 968.

after some time, Paragon in Sussex traced it to a drained battery on a original fitment Tracker. it was just a matter of finding the Tracker ??

I would think the best way forward is to measure the drain while popping out each fuse, until the drain is discovered

but common drains are
the glove box light
under bonnet light
Alarm system
The radiator switch failed and the cooling fan seized

should be able to trace it

Thanks guys - hadn't considered a tracker but will look for it next time.

The tracker in mine was wired straight to the battery terminals, so it was quite easy to find and disconnect.
If you are lucky, it may be as easy to find in your neighbours car.
