CL77 Horn mount

[ugmold]

Hi folks,
I'm up and running so it's time to refine some other things. The horn to start. It does not work with the button and was hanging out the back of the headlight. I opened up the HL and saw one nut on a screw, and thought the other was a stud, but is a broken off screw. I attempted to tighten the nut and snapped it as well. I ran a 12 volt battery to the horn directly and it is working (!) Cool looking object, mine is a bit rusty on the chrome. But before I pull it apart, can those screws be replaced?
Thanks,
-Forrest

Well I had to take a look further and might have come up with a solution, albeit, not a perfect one. I took the horn apart, 6 screws outer chrome cover. remove 3 screws, 1 that is an adjustment screw, and two that just hold things in place, but nothing is budging as far as the coil and magnets, so I put the screws back in. Smoothed off the what was left of the broken off screws, made smaller grommets from a gas hose. The screw ends will make it into the headlight housing where hopefully the nuts will have enough to attach.

Original grommet, has a metal sleeve in it, not pictured.

The switch seems to show continuity at the 2 black wires in the headlight, I forgot that the brass/copper tinfoil piece was not used when I swapped out the bent bars and putting it back on I guess grounds the switch.
So I think I'm putting the horns diaphragm back on and something I did not notice when taking it apart is on the back, the bar that attaches at the center has a notch on one side and a raised section opposite, see pic, right.

I have it now with the notch facing up which would be facing that screw with the red washer, looks like a conductor up there. It works holding the diaphragm on by hand, but is dead when I screw the chrome cover on???

Hope this isn't terribly confusing.

You will have to completely disassemble the horn to replace the studs/bolts/screws what ever you want to call them. If I remember correctly the tab goes toward the points/breaker and moves them when power is applied. The points act as part of the circuit and often the whole problem with a horn if dirty. Look close and you should see.

Thanks bamacl,

Adjusting that screw did it. The nuts seemed to grab enough to hold it flush, I think it will be stable enough given the fact I won't be doing any hard off roading. Handlebar switch work now as well after I put the brass foil wrap under the switch.
