Jan:
A couple of things I would like to know is whether we are really dealing with a
good battery and whether the fan belt is good and properly adjusted. A glazed
and slipping belt could cause some of these problems and and a sulphated battery
could, as well.
However, I looked up polarizing methods in an old text and for a field grounded
internally generator (which I believe ours are) it says (in CAPS) " NEVER APPLY
BATTERY VOLTAGE TO THE FIELD TERMINAL OF THE REGULATOR. TO DO SO WILL DESTROY
THE REGULATOR. REMOVE THE BAT AND FIELD LEADS AND THEN SCRATCH TOGETHER"
This may be part of the problem, since some may have been telling you to
polarize for a generator with an external field ground in which you jumper
briefly between BAT. and GEN (ARM) terminals on your regulator without
disconnecting. Also, as I mentioned before, all of this is supposed to be done
"BEFORE STARTING ENGINE" (their caps).
Let us know how it all works out!
