Yo Ho is at the dealership for diagnosis and repair of a minor electrical
anomaly. This past week, while running with the battery switch on "BOTH,"
and cruising at 4000 rpm, I noticed that the voltmeter, after about an
hour, dropped to 11.6 volts.

I shut the engine off, switched onto one battery, and the voltage went up
to about 13.5 volts, then after about an hour dropped again.

All the battery connections are tight.

I'm guessing voltage regulator, but that's just a guess.

A brand new $1.00 to whoever guesses what the dealer's mechanic diagnoses
and repairs.
