My low tone horn ain't working, the other one is fine though.

I suppose I'll have to take it off and have a look.

Just took it off for a look and then pressed horn with my meter in spade connectors and there is voltage coming through but not 12 volts:confused:

Can I turn the screw on the horn in or out to make it work?

When you test the voltage are you using the horn earth wire or a known good earth, that way you will get correct voltage, but determine earth fault

Do you think it would be ok to wire it from the 12 volt live on the other horn or would it be to much drain?

Again not sure but could be a relay fault? Separate relays? Always have to sort this type of problem on a trial and error basis, that's the limited extent of my electrical knowledge.

I guess if there's a relay then it wont cope with wiring it off the other live thats pumping 12 volts!

wht thats doing is ,I could be corrected if I am wrong here is that the earth side is helping the live to function, so I would trace your live side to see if there is a build up of corrosion at a joint as it detects a good earth,but no power,becuse of resistance somewhere.
