I am not an alternator guru by any account. I do read all of my BB material. There are several warnings associated with different equipment that specifically states to disconnect the battery pack before maintenance to prevent alternator damage. One that comes to mind is the Webasto. I shut of the master battery switch in the engine bay then disconnect the main battery ground before doing anything except verifying power. I was taught to disconnect the ground first at all times. Then reverse the procedure. Perhaps operator error has something to do with premature failure also.

Alternators should not go out as often as they do on Wanderlodge
busses. In search of the root cause of this common posted failure,
forum member JoeW brought up the theory that a big bank of low
charged batteries may tax the alts, heat the alts up and cause early
demise?????
JayDarst runs the alts to power realtime inverter run 110v ac while
driving which should disprove the heat theory but Jay installed non
oem spec alts. His upgrade may be the ticket
I always wondered if 'shore charging' caused any heat or effect to
the alts. or are they diode protected??
I would like to learn the reason why alts go so quick prior to
paying the tuition of alt replacement. JoeW turned me onto a site
that has great tech documentation on batteries and
charging.
Understanding the complex system of voltage production and
maintenance in the bus may not be necessary to ownership but should
help avoid costly mistakes and prove clues to upcomming need.
