Well I have hooked everything up and nothing. I took the horn back off and manually touched the wire to ground it and nothing. I ran a wire off of the battery and touched the horn connector and they both work great. I notice on the post of the regulator it says batt, ground, horn and ign on it. I guess I need to grab the multimeter and test the regulator to see if it is any good. If it doesnt test good anyone have an idea of where I get get a new regulator?
