one day i tried to turn on the car the battery was dead, so i jumped it and drove the car about 50 miles. next morning the battery was dead again. so i went to pepboys and bought an optima red top that ran me about $150. same problem tried turning the car, 2 days later and it was dead again. i thought it had to do with the yellow top sitting in the trunk. i unplugged the yellow top let it sit overnight same problem in the morning battery was dead again.anybody having same problem,any ideas?
