Tks!

Ordinarily the way to check for a drain on the battery is to make sure everything in the car is turned off, disconnect the negative wire clamp from the battery, and put a tester between the clamp and the negative battery post. If there's no draw on the battery, no current will show up.
BUT... make sure you have your Radio Code (if your radio has one). Also, it takes awhile for the Boxster to turn everything off and I'm not as familiar as others in this forum with that element of this test.
