    As it says above air died and have low voltage message on controller. Belts are ok, can't find a bad fuse any body have any ideas? It is a carrier comfort pro
    Thanks

    A dead altenator will do that.

    That is a capacitor excited generator. The capacitor may be bad. When was the last time it was serviced? If it's running slow or sluggish it won't spin the generator fast enough to create the proper voltage.

    Took it to carrier that said bad generator. $1876 for a new one. Not today. Will take it off when I'm home I have a friend who rewinds alternators and generators I think it needs to go to him.
