I thought I had my horn issue resolved. I have a couple last scenarios/questions for the electricians in the know. I tested my horn with a 12v battery, and it sounds great. I started to install it in my 6v system and only get a click and little hum from the horn. Based on the design I assumed the horn was old enough it had to be a 6v horn. See the picture. There are no markings anywhere on the horn.
Does it need to be wired through the horn relay before it will work or is it in fact a 12v horn and that is why it won't sound off with 6 volts?
