I just got a 1991 ford thunderbird and the battery keeps dying when I shut off the engine the you can still hear a motor running from the master cylinder when I take off the negative part of the battery it stops what could be my problem
I have a 1990 Tbird that the battery has died a couple of times. I also hear something running that sounds like a fan, etc. I think it might be the electric fuel pump. Is there a relay that causes it to continue running when the car is off?
