During the school year, when i am driving my car every day, the battery operates in a satisfactory manner. During this time, the car does turn over for about 2 seconds before starting, which may or may not be a related issue, so dont let that confuse the problem.

During the summer, if i dont drive the car for 4four days, it will not start. The battery drains to a point where it wont start over a period of no less than 4 days.

From searching, i have found that problems like these generally tend to be one of three things:

A) The alternator. Something tells me this isnt likely, because of the nature of the problem.

B) The battery. Old batteries may just not hold their charge for a long enough period of time.

C) A current drain somewhere in the car.


So my question is, where should i start? Also, how do i check for a current drain? I do have access do a multimeter, but i dont know how to use it.
