LC4 voltage problem
Scott Whitford
the system within seconds of installing new bulbs. I measured the
voltage across the battery with the engine running and it measures up
to 30 volts!
OK, so I assume it's a bad voltage regulator and I plopped down the
$200 for a new one. I just picked up the part from the dealer, but now
I'm starting to wonder if it might be a voltage _generation_ problem
that caused the regulator to fail in the first place. I'd sure hate to
fry the new regulator and be back to square one.
Does anyone know what voltage to expect coming out of the coil on an
LC4? Could the windings or stator be bad?

Long time since I studied power but I would think the kind of faults you
get in a coil are shorts.. and I can't think of a way to drive the voltage
up using less inches of windings/coil. Don't act based on my input/poor
memory... I'd hate for you to ruin your coil based on my weak memory. Good
luck.

I'd expect about 1 volt per hundred rpm into an open circuit. There's
a good troubleshooting guide at www.electrexusa.com however I don't
agree with all the other information on their site.
In my opinion it's highly implausible that a stator's output can be
increased by electrical defects....if that happened what was the
designer doing about optimization? 8-)
Honda's VFR series of bikes is famous for having charging system failures.
Mine, alas, is no exception. The gist of the story is that faulty wiring
and/or bad batteries seem able to induce RR failures by a means I can't
figure out. Details are at

Good luck!

bikes is an integral part og the charging/voltage regulation system. Your
battery is wide open.

strating it if its open circuit? Jump starting?
Scott Whitford
Tim,
No, the '95 model did not have an electric starter - just the good old
kick lever on the left hand side. Starts really easily, actually.
DLM,
The battery on this bike is really small - about the size of a pack of
cigarettes. I've never replaced it, and it's never held a charge worth
a darn. This has never been a problem, though since there's no
electric starter. Once the engine's running, the lights have always
worked fine until recently.
So how does the battery being "open" cause the voltage in the system
to go up to 30 volts? There's a 30 amp fuse in the circuit, and it's
never blown.
I *really* hate electical problems!

Scott, I don't know how someone can say that the battery is the problem. The
battery cannot generate any voltage. Batteries store electrical charge.
Other devices (generators and the like) produce the voltage.

Has the bike ever run the lights without the battery in place? I doubt it,
the battery sounds like it is eesentially open, an extremely high internal
impedance. The battery is critical in keeping open loop charging voltages
down.
Just try any lead acid battery (probably gel-cel) that will fit in there.

My KTM 620 SC ('98) doesn't have a battery. It has a capacitor (60V,
approx 4000uF) though.

It turns out that it WAS the voltage regulator. I installed the new
one and the system voltage now measures between 12.5 to 14.0 volts
across the battery terminals with the engine running depending on rpm.
I installed all new bulbs and they stayed intact through a good test
ride.
The battery still doesn't hold a charge worth a darn (although it does
hold it somewhat...).
Volker, the '95 also uses a big whopping capacitor in the system,
mounted right next to the voltage regulator.

Ah - OK. You're fine with leaving just that part in your bike - unless
you don't need any stuff to work w/o the engine running. The indicators
will behave a little "strange" at low RPM though and the headlamp is
also going dim but - hey, who cares? ;-)
