Horn Malfunction

[Bob1150GS]

Hi to all as usual when I post it's because I have a situation or issue that I have not dealt with before this one is my horn (Whoo eerr matron) a bit topical for me.
So to the problem. Did my pre-ride checks this morning all OK but no horn. Got to work had time to lift seat and check fuse OK and relay OK. If I pull out the small plug what reading should I get across the two wires or plug with a multi meter or should I use a 12V lamp tester. Or is there a known problem area to check. Would apprieciate a quick reply as I'm off to Nottingham in the morning and would like to fix it before Thursday test day duty. Thanks in advance as ever

Connection

Have you checked the connection from the cable to the horn itself?

If you cannot locate, it then suggest a Stebel Magnum replacement..
I have had one fitted.. brilliant!.. better than the stock..

Cagers, know when your there now..

Use a 12volt lamp with a couple of bits of wire soldered to it. Locate the horn plug near the steering head/horn, unplug and connect the lamp between the two connectors on the feed/loom side. If i remember right it is a small connector, so be careful not to short it out. Switch ignition on, press horn. If the lamp lights your horn has proberbly died. If the lamp does not light, its a wiring fault.

My horn died on my 1150GS - it was replaced under warranty so don't think it was anything to do with the wiring as the dealer just did a quick swapover.

Just looking for confirmation

Had a little play this morning and as the horn will not work connected direct to the battery I have assumed that its the horn. So day off tomorrow and want to get it sorted, therfore is the live feed into the horn then out of the horn and pressing the switch makes to ground or is it worked some other way? Hope I've explained that OK sparks not my subject. Replies on here please and not by post card.

i do not diectly know how your horn is wired, it would be reasonable to be wired as you say, but most horn's that i have seen ar rubber isolated hence need two feeds to it, therefore it should make no difference (apart from the sound) where the connections are made


anyone confirm this?

Most horns have a permanent live feed and a switched earth.

However,if the horn has two spade connectors on it and you connect one horn terminal direct to the battery positive,and the other horn terminal direct to the battery negative (or to a good earth) and the horn doesn`t sound, then it`s fecked.

If the horn has one spade connector.....connect the spade connector direct to the battery positive and the horn mounting bracket to the battery negative ( or to a good earth ). Again..if it doesn`t sound,it`s fecked.


To further confuse the confused......sometimes a horn that appears to be fecked just needs the adjuster screw tweaking (if it has an adjuster screw)

Might be the switch
