Need wiring instructions. 2 wires coming out of the back of horn. Need to know if its hot and ground or hot, hot and grounds to the horn chassis.
It is 12volt DC. I'll try what you suggested.You would figure if it was AC you would have 3 wires coming off of it..
Zooming in on the tag it reads 12V which I am assuming... DC.
reversing polarity should make the motor spin in a reverse direction.
If the horn is grounded to itself you could get a meter out and test for continuity..
whichever wire shows you a reading is ground.
Know how to wire it?This is a vibrating diaphragm mechanism. No motor.
The cycles says 60 that mean that it is 60Hz and that also mean that the horn is AC.
The Voltage is 12V but NOT DC (Direct Current) but AC (Alternating Current) with the frequency 60Hz.
DC can not have any frequency because it is as the name says Direct Current.
You must find a converter for 115VAC to 12VAC that gives out more than 4,5Amps (54Watt).
