what is making my charging system shut down after about 60+/- sec. of running ?
Check alternator fuse.
change the alt...
alt. has no fuse on unit. The charging system is working for the first min. or so! but then it trips something , & the guage drops from a charge to no charge reading & light comes on! if i shut it off & restart, it will charge for the first part again ! and so on ........
Fuse would not be on unit it would be in the fuse box under dash or under the hood.
If any fuses in that circuit were bad it wouldn't charge at all, so that answer doesn't make sense. (1) Load-test the battery to see if it's failing under charging/load. If that's OK, plug a computer into the bus and get the error code. It could be the PCM, the voltage regulator, the battery temp sensor, the alternator decoupler, or a bad ground. I don't know which of those your Jeep has without knowing the year, model, engine and trans type.
