Did you check voltages while running and not running?

Agree with Cheese. A good charged battery should be 11-12 vdc disconnected and 13-14 vdc when connected and engine at speed. The 13-14 vdc should be attainable with all accessories energized (lights, PTO clutch, etc) with a good alternator and battery.

It is generally accepted that a fully charged lead acid battery will read 12.8 volts after resting and will read 11.8 volts when depleted.
A lead acid battery can be used at a lower voltage but it's life will be greatly reduced.

For vehicles 14.2 should be the voltage reading when charging and taper off slightly when charged but should be over 13 volts.
Also, if the voltage on the battery went much below 10 volts and especially if it went to near 0 volts it could have been damaged.
