There are old threads about tracker systems draining starter batteries.
I have personal experience with this on my Terrano. It had a 0.5A constant drain.
I am sure this was not the case when I bought the car 2nd hand - it developed over time.
An auto electrician found and removed a tracking system and the fault was gone.

Now I find a 0.8A drain on my 2012 3.2 DiD Pajero. I have only owned it for 2 months and used it regularly enough not to notice anything. But recently it has been parked for a long time (10 days) and then it would not swing the motor fast enough.
The battery does not lose power when disconnected. Pulling all the fuses (one by one) does not eliminate the fault current.

So I suspect that the culprit is once again a defective tracker system.

And now I need to find someone to track it down and eliminate it with extreme prejudice.

I'm in Gansbaai, near Hermanus. Can anyone recommend an expert in the Overberg. I could even travel as far as Somerset West - and Cape Town if I have to.

Thanks
