My son's white 84 is a battery killer.  It may be that we just haven't
been running it enough.
We put in a new radiator yesterday and that went fine.  The battery was
low again.  It's a
brand new battery.  When the old one failed I checked the voltage with
the engine runnging
and it was higher than with the engine off.  So does that mean it's
charging?  We'll make an
effort to drive the bus every couple days for at least 15 -30minutes at
a time and see if the
battery holds.  Another question, the whole alternator wobbles forward
and back some.
I don't notice anything like that in the other busses.  I didn't see
anything different in the brackets.
