The battery runs down after a few days of not driving the car. The battery is fairly new. I make certain the lights are off and the cars are shut tight. It appears there may be a short in the system which is draining the electricity. How can I test the system to locate the leak?
Grab your multimeter and head to Youtube and look up how to do a parasitic drain test on your vehicle. Wouldn’t hurt to have the battery tested too to make sure that it hasn’t been damaged by being run down so many times
