I have a 1999 ford f250 super duty. I turn on the ignition and it imediatly kills the battery. I have checked the battery and it is still good. I change3d out the starter and it still will not turn os
Is it shorting out somewhere.
Can a relay cause this short? When I disconnect the battery and reconnect it the power is fine until I turn it over. then it dies and I have no power until I disconnect and reconnect the battery.
You have a problem with the ground connection. Its either between the battery and the car frame, or between the car frame and the engine block.
I'd replace those terminals and check the ground from frame to block.
