My sportster was clicking so I took the battey out and charged it.when I put it back in it wouldn't do anything.the headlight works and the battery shows 12.66 volts.it won't start,not a sound.the horn and signals won't work and neither will the brake light.all worked before.please help.

See if there is a loose wire near battery. Never can tell, also could be a fuse.
A $5 test light can make short work of this.
