I have a PA300R that i can not get the siren side to work properly. Everything worked when i removed it from a wrecked engine. Now that Im trying to put it in the new truck I can only get the PA function to work. When I press the horn button on the switch panel i get a low hum when I press the off switch i get a pop through the speaker Wail Yelp and HI LO do nothing. If anyone can lend some advice I would appreciate it.
I have the Installation and operation instructions but still cant seem to get it to work.
