regal alternator help 3.8

[jacobdavis1979]

Need some help again guys. My 92 regal with the 3.8 keeps popping alternators im on number 4. They keep running the battery dead overnight and get really hot to the touch like you can see smoke there so hot and it hums. But if i unplug it the battery wont go dead. Im on number 4 because they fry themselves if i leave them plugged in to long. Any ideas guys?

And isnt the brown wire supposed to be a keyed hot not full time? Well its always got power

sounds like you have a short somewhere if the battery drains overnoght and alt get hot to the touch.

is it a 92 ? 92 regal is a w body the wiring diag is for a g body check & see if anything has been jumped in the fusebox an aftermarket radio wired wrong can do this also has the alt plug been replaced ? it may be wired wrong also dave

Yes the brown wire should only have power with key on.check for short in the alternator harness.unplug ignition switch and see if the brown wire goes dead,if yes,replace ignition switch.
