Air horn isn't working!

[cjhillman]

For some reason I'm struggling with wiring in my air horns!

I followed this diagram but its not working :



This is the over all wiring. The negative from the compressor and the relay 85 are bolted to inner wing. The relay positive 87 is going to the battery terminal and was clamped behind.






The switch goes to the 86 pin and the black wire is screwed the inner cill.




I will tidy this up later once it works and there is a fuse to go on the battery terminal .

Thanks,
Chris

are you getting power to leg 86 when you press the button??

I haven't got a meter to hand at the moment. I tried connecting the positive straight to the battery and it didn't do anything then :s I did get the compressor to turn the other day buy connecting a 9v bat to both terminals though.

connect the live from the switch to the feed to the compressor, push the button, if it works, its a duff relay, if it dosent, you have either no power going thru the switch, you have picked a no live feed, or the switch is fubarred.

It sounds like you are just connecting earth to earth with the switch if you say 85 and 86 are earthed. You need a positive feed there, connect 85 to the battery positive if the black wire from the switch is earthed!!

Also, fuses! Where are your fuses?! Tut tut..
