Alternator failure

[Couchmen@aol.com]

The alternator on my '79 B recently broke/burnt out/stopped working and was
replaced by a garage.  The new one also failed within about 100 miles.  The
garage said it was a bad alternator and replaced it (free of charge).  This
happened a number of times until I replaced the battery.  The alternator now
seems to be OK.  I thought an alternator had a current limiter in it, so can
anyone explain to me how a battery could cause an alternator to burn-out?
