Electrical problem
1995 Jaguar XJR Two Wheel Drive Automatic 88k miles

can anyone help me? I have a car that drains the battery even when sitting off in the driveway. Replaced the battery itself twice and dead the next morning so I know it is NOT the battery....My Mechanic has pulled all the fuses and that is not the problem either..any suggestions to save me lots of time and money? Thanks...

Hi there,

You will have to do a current draw test, and check the alternator for a faulty diode, as this can cause a current draw that will drain the battery, start here.
