could be a problem with your alternator, putting too much charge in. regulator burned out maybe?

or if the battery is really dehydrating you could have a crack in the battery case itself

anything over 15.5 volts with the motor running  1000-2000 rpm is overcharging the battery.

manual says check at 5000 rpm WTH

Anything over 14.5 is high and a bad battery that is sulfated will also cause problems.

"With the headlight Hi beam on, restart the engine.
Measure the voltage on the multimeter when the engine runs
at 5,000 rprn.
STANDARD :
Measured battery voltage (page 16-51 <Measured charging
voltage (see above) (<15.5 V at 5,000 rprn"

page 16-7 honda valkyrie manual also page 16-3
look it up

Thanks for the help. This was a problem my brother was having on his V Star 1100. After replacing the battery with a new one from Walmart he still had the problem but he`s working on it. Thanks again!

You are right, Shocked  but its still to high,  Grin  batteries fully charged at ;12.3 volts dont like to be charged at 15.5 they will die a early death  Cry
