There is something draining the battery in my car. The alternator works, and the battery is new. Anyone know?
Something is draining my battery when my car is not on.
solutions to that situation are hard to find some times. i found a drain in the charging system in my project car. as someone else has sad, you can do a current draw test and pull independant fuses to see where the drain is and then focus on that circuit.
