Hi,
I am trying to fit an air horn to my boat (same as car electrics but without the ECU).
i think the relay is wired wrong because without relay it works & with relay it wont. i put a tester on all connections & the switch is providing 12v when pressed & the constant from the battery is also providing 12v.
I did notice when i wire it one way shown on the internet i hear a click straight away as i ad the last wire even before button pressed (30 to battery+, 85 to earth, 87 to horn+, 86 to Switch) but no sound from horn, when i swap wires to match chinese instructions no click as it should be but still no sound from horn when switch pressed.
as horn works when connected direct to switch without relay using same wires just block connecting in place of relay. i can only assume the relay has been put in the wrong way round inside so the pins are not as numbered?
my question is, as when tested no fuses blew am i safe to use without the relay?
