I have a battery problem. Seems it will never start the mower after
sitting unused between mowings. I can give the battery a quick-charge
and it will start the mower.

I measure just over 12V on the posts while the mower is running, but
only about 10V after motor is off. The battery is less than a year
old - and I bought it because the older battery did the same thing,
and I figgered a new battery would solve the problem. It didn't.

I thought some told me that there should be an alternator on this
beast that would charge the battery while mowing. Is that so?
I sure cannot find it in my manual/diagrams. I thought maybe it needs
replacing. Where would it be?

Anyone?
