I have a 2001 X5 4.4l. Just replaced alternator, theromstat, and belts. On check ride to test car, battery light came on again. Drove car to my garage and shut it down. After shut down, tried to start the car and engine will not crank. After an extensive search found on the internet, found out that fuse#5 might be the problem. Replaced fuse #5, still blowing fuse. Disconnected oil level sensor, still blowing fuse. Does anyone know what components are related to fuse #5. Thanks in advance.
