ADVICE NEEDED: Sick 91 VFR 750F. New Charged Battery lasts only 9 miles - HOW to diagnose?...

Greetings Fellow VFR-ers,

Hub a duh.
Hub a duh.

My beloved 91 VFR 750F (had for 6+ years now) is sick.
Just took it out of 9 months storage.
Almost-new battery was too low to start.
Jumped via my Jeep. Started, no problem (LOVE that about VFRs!)
Drove home... died after 2 miles.
Took battery home.
Hooked up to "smart" charger/tester - it said "replace or service battery".
Bought a new, fully-charged battery from local battery shop.
Installed.
Drove bike on wonderful 12 mile jaunt through local villages.
At intersection about 7 miles from home... engine died.
:-|
SOME juice still in battery - but NOT enough to turn it over.
Took battery home to charge overnight.
Called local Honda dealership (we all trust so very very few of them).
They (the only guy I trust) said might NOT be alternator/stator, but maybe (cheaper) power regulator.

NEED HELP from fellow VFR-ers!

HOW best to diagnose a battery which WON'T charge?

Help help help.

Cheers,
-Mark

Sound's like another one ... at least Scub's given you pointers of where to look - check the fuses by the battery first - but also note there have been issues with a hidden orange connector (its taped up within the loom) - see Tinks post/photos in this thread

Its been said loads of time - it seems similar gremlins have been attacking a lot of vfrs lately so can the Mods create a HELP thread where really usueful stuff can be posted for easy reference?

It never makes sense to change a battery without testing the charging system at the same time.

A non-functioning charging system will kill battery #1, so some riders just plop in battery #2, which promptly fails because it's getting NO CHARGE !!
