Charging Battery Problems 2001 S
 

Hi Guys
I need some help pleas !!
I live in Aruba and just got my 2001 Boxster S out of the Container yesterday and the car won't start .
I jumpt it with a mobile start kit and it runs well, after removing the starter cable it went out again with the old battery.
I had a brand new battery installed and the car runs fine, I double-check the voltage and it had with the running engine only around 11,3 ( on the new battery !! ) I removed one battery cable and it went out again.

Any Ideas what to check first before I pull the alternator out .
The funny thing is it was running fine before we put it in Miami in the container to send it to Aruba.
Any help will be fine .

Kasi
