Push Button Horn Installation

[George_San_Jose1]

If you have an ohm meter, the switch should be open (high resistance) normally, and less than 2 ohms when pushed. If the push button switch didn’t come with the horn, unless it was designed for a horn circuit you may run into problems. The switch has to be designed to handle the amount of current the horn uses, otherwise you’ll have an early failure. i.e. the switch may be a normally open design, but the first time you pushed it, due to a current rating problem, the current might have welded the contacts together, making it an always closed switch. I’ve had that problem happen on custom switches before.
