alternator question.1996 gl 1500 se goldwing

posted on mctech but got no responce
1996 gl 1500 se goldwing.

hello. i was on a ride and stopped on the road for a break, pushed the
button and click.
proceeded to the next town, found a Napa store, they had THE BATTERY for my
bike {smiles followed}.
when i pulled the old batt out 2 of the cells were REALLY hot, shorted out i
suppose.
checked the alt output no go. checked into motel had steak and rum.
ran home next day after pulling all the fuses except ign and starter.

ok now i have replaced the brushes on the alternator, it wont put out
anything.

what happens to these alternators when they are tasked with charging a
shorted batt?
do the diodes go out? is the rectifier bad?
i tested the stator, slip rings, armature and rotor. all check ok with
ohmmeter.
how do i test the rectifier/diodes. the goldwing bible doesn't specify how
to check all components.
i am low on the fundage and can get a new alt from a bud at Honda for 200$
but if its just a component i would rather do that.
BTW bike has 31k on it and no extra load on the electrical system{i.e. rings
of fire, lights }
thanks in advance for your time to respond.

First thing I would check is the rotor winding. Do this by using an ohm
meter to check that there is continuntiy from one slip ring to the
other. (These are the brass rings that the brushes rub on.)
I will guess that they measure open. If so you need a new rotor. In my
many years working on GL1500's this is the most commen cause of a no
charge situation.

thanks bruce.
you are right. rotor is shot. getting a new alt for the hotwing............
