Battery is discharged. At rest a charged battery should be 12.6 or better. Need to check further to find out the cause of your discharged battery: 1) bad battery, 2) drain on the battery bringing it down, 3) charging system fault that keeps the battery from fully charging.

Charger on battery for 3 hours, voltage 12, key on 11.9, WOT 11.84, idle 11.81, off 11.9

What age is the battery? Check water level in Battery? should just be covering top of plates.
A good 12volt battery should be around 12.6 to 12.7 volts at rest.
At 11.9 volts, your battery is barely at 40% of its capacity. It may be done.

It is not charging. Something wrong with generator?

Try the voltage regulator test: disconnect the yellow wire to the starter generator. Run a jumper wire from that terminal on the starter generator to ground. Run the engine up to speed for just a moment and see what voltage you read at the battery during that moment it's running. If it's still the under 12 volts it's a generator issue. If it goes high, over 15 volts, then it's a voltage regulator issue.
