Hey guys, well not really good electrical wise, my horn does not work, it clicks when i press it so im thinking the relay is working. i checked the horn underneathe the battery and the wires connected, maybe its the fuse but do not know where the horn fuse is located. can anyone point me to the right direction.

hey - if you can here a relay activating when pressing the horn switch, then your fuse is good, but i thought horns just use straight 12v power, but i could be wrong. could test just the horn by putting a jumper wire on from the positive side of the battery to the horn, most horns are already grounded by its base - hope this help ya- cheers

you shouldn't have too cut the horn wire, just attach a jumper to it, hold it to the horn under the hood, for a sec, if it dont sound off- its a pooched horn, dont hard wire it right to the horn and let the horn bellow too long- you'll fry it

You may be able to salvage the Horn by adjusting the little **** on it with a pair of pliers, just turn it while someone is beeping the horn, if that doesn't work just go to a JY and get a new one for a couple bucks...Tj

ive had that click and no horn

i just have someone hold the horn button down while i kick the actual horn(s) itself.

usually just has crud, mud and water in there, keeping the vibratin sound deely from moving
