I own a 1993 Maxima. Last night the ABS light came on, but the brakes were fine. When I turned off the engine, there was an electronic sound coming from under the hood. It sounded like an electric motor running. This ran the battery down overnight. This morning, I jump started the car and everything worked great and has all day. No ABS light or noise from the engine compartment. I'm stumped! Can anyone shed some light on this? What can I do to stop it from running down the battery short of disconnecting it? Any help is appreciated.
Thanks, David
