Indicators and horn stopped working

Your coil problem, change with the new one.

Sounds like the solaniod is duff ( thats the thing that makes the clicking sound ) or it could be a short circuit which would explain the weak horn

suspected bad ground connection within wires to frame.

Change the spark plug, that may help. <div>Regards</div>

if the horn and the indicators are on the same handlebar maybe it is a problem with the operation there?

sounds like you have a dirty or missing ground connection or a fuse that's bad. the ground problem is usually best left to a technician (it can get pretty involved, but the fuse is a quick check and fix you can look at it and see if it is blown and get a new one at any auto parts store.
