Q: Car won't run due to electrical problem.

asked by on

I had an electrical problem that is draining the battery. I got a new battery and alternator installed. It drove fine and then went out the next morning and would not do anything.

A load that stays on after the key is turned off is called a parasitic load, it must be tested for while the key is off and with an ahmmeter. Have a certified mechanic, like one from YourMechanic, test for and find the cause of your drained battery.
