2011 Road King won't start. Tried jump starting but still wouldn't start. Put a trickle charger on it but doesn't seem to be charging.

 

Have you been keeping the battery on a trickle charger? I am suspecting a bad cell in the battery, a common problem on ones with a few years of age on them and as well as ones that aren't kept on tenders or trickle chargers.

 

Sooner or later, we are going to need some DETAILED information. "Won't start" covers a LOT of territory. Do you have a security system? Does the fuel pump prime when you turn the bike on? Does absolutely nothing happen (dead battery or blown main fuse) Does it crank but not fire? Does it make a clicking sound, or is there a rapid clicking almost like a buzz when you push the starter switch? How old is the gas? Is this the factory battery or a newer one, how old? How many miles? Any modifications? Did it run well UNTIL you did something? Changed grips, handle bars, wash with a garden hose or high pressure sprayer? Has it been in storage for an extended period? How bright is the headlight when you turn on the bike, or doesn't it light up at all? Does the starter "whirr" but not spin the engine? Any stored engine codes?

ALL of this and anything else you can think of might get somebody pointed in the right direction.

 

Not enough info from the OP to even begin "guessing".

 

Yea, we need a little more than my bike won't start, what's wrong?
If your battery won't charge, I would start there.
