I need some help from someone who has gone from 6 to 12 volt and changed polarity to neg. I can get my horns to work but not off the three terminal relay.I have insulated the horns that may be a problem.
s terminal to horn button
h terminal horns
b terminal to pos on battery
this is a 41 ford with trumpet horns
not sure what I am doing wrong. Before I insulated the horns I was having the same problem.Because I changed polarity my wires that use to be live are now negative any help would be great thanks paul
