re: Dead 164 (battery problems)

[Jeff Hanbury <j.hanbury@xxxxxxxxxx>]

Before christmas I posted a question about our 164 which would 
flatten its battery over 2 days of no driving.

Thanks to everyone for the helpful suggestions! They were much 
appreciated.

One comment was that there might be a small continual power drain and 
that this might be traced by pulling fuses one by one while checking 
drain at the battery with a multimeter. Well, we did this and found 
two suspect circuits. With both of these fuses removed we left the 
164 sitting for more than a week... and it started perfectly! This 
would never have been possible before.

So, now all I need to know is which particular device(s) in these 
circuits is causing the drain. If I can't find it in the car disk I 
may be back with this question...

Oddly though, with both the questionable circuits active, the power 
drain does not double. With either one individually and also with 
both, the drain is (from memory) 30mA. The fuses are for "control 
units" (fuse #1) and for "dome lights" (fuse #5) and are in the batch 
of 6 fuses which reside above the rest of the fuses.

Thanks,
