Thanks for the info.
The inverter was connected directly to the house batteries and at the time of the issue was not powering anything.
V belt is brand new so no issue there.
Today I took the RV for a 20 mile ride and everything was perfect. As soon as I disconnected that inverter everything is back to normal but I dont understand why.
Something wrong happened which sucked all the juice from the alternator and for whatever reason it was isolate from the coach my probably the electronic switch (isolator).
I will buy a spare alternator just in case.
