Come to think of it, this makes some sense.

I had a similar problem on diesel SUV a few years back
where there was high resistance in the charging path.

The regulator eventually failed in perpetual "on" after
it kept trying to push watts into the battery through
a high resistance path.

Some bozo kid charged me 50 bucks to hook the damn
car up to a machine that went ping and pronounced
the regulator bad but totally missed the high resistance
problem. I finally found a 3 volt drop between the engine
and frame indicating a screwed up ground cable.

If it were my bike, I'd look real hard for a bad ground or
+12 connection in the battery connections, or if it was
new, insist that the dealer run this check. Wherever
that voltage reading was coming from, it should match
to a reading taken directly across the battery terminals.

How pathetic. Solid state electronics have no emotions.

Feeling like a small green lizard this AM, are you?

The RR might sense voltage from a remote point in the wiring harness.

This was a comon Honda problem.

Excessive numbers of production break connections in the wiring
harnesses of VFR's led to high resistance and voltage differences that
caused many RR's to fail prematurely.

I added a cheap Pep Boys series ammeter to the charging circuit of my
old Chevy station wagon many years ago and got into problems with high
resistance in the
voltage sensing loop.

It seems that the ammeter studs only had one washer and nut to attach
the
leads to the ammeter.

So the bottom of each terminal was pressed against plastic instead of
metal.

The plastic heated up due to passage of current and the resitance of
the voltage sensing circuit increased.

The voltage regulator increased current to the generator field to
raise voltage, which increased the heat at the ammeter terminals, etc,
etc, in a self-destructing
feedback loop...

Wrong, the world will not be surprised to hear. The problem was
usually caused by one or both of two factors. The first (relatively
rare) was corrosion causing shorts. The second was that Honda mounted
the unit very near the engine with no cooling flow of air and it
overheated. Honda upgraded the reg/rec with a finned unit, which
generally solved the problem. I've even heard of CPU fans being fitted
to cool the reg/rec.

If the problem had been due to too many 'production break
connections', then the upgraded unit would have failed as well, since
it's a simple plug-in retro-fit, and the number of wiring connections
wasn't changed at all.
