Any ideas what to check for when the battery on the car is drawing down over a period of time? First it's a 95 chevy sub with all of the options. I removed the battery bolts and changed them, and cleaned the wire ends, and I took the altenator in and it passed the test. The battery that was in it first, was new, and I changed it back to the old battery that was in it, and it worked for 2 weeks before starting the whole process over again. Any ideas will be put to the test.
