Hi Guys
I have just bought my wife a Boxster for X-Mas to replace her beloved MGF
The first day home the alarm went off and we found that the battery was completely flat. 1st problem was how to release the front lid - a quick google search pointed to supplying +12v to fuse C3 which we duly did, opened the lid and replaced the battery with a new Silver 85Ah 850CCA model. All was OK for another two days until the same thing happened
Monitoring the static drain on the battery shows a very strange pattern. Normal background drain is about 50mA but this spikes to 6A, 8A or even 10A for about ten seconds every minute then it drops back down to the normal 50mA
Systematically removing the fuses whilst monitoring the batter drain led us to fuse E3 (30A) which would appear to be related to the Power Seat Memory which is doubly odd as the car only has manual seats!
I have a workshop manual on order to help me with further diagnosis but until this arrives does any of you tech savvy guys have any idea what could be occurring ?
Cheers
