Re: '37 horn (12v)
19Fordy, I am sorry to say that a 60 ohm resistor will not work at all for powering a 6 volt horn or horns on 12 volts. It might work for gauges which only draw about one amp of current. A pair of 6 volt horns would draw approx. 15 amps or more current. One resistor does not suit all conditions. To work out the resistance value in ohms required one first has to establish the current draw of each horn. Many suppliers such as MACS do have available a resistor capable of 6 amps or more load which would be required for EACH horn. Some people as stated previously have connected the two horns in series which will have the desired effect to a point. I have tried this but the sound of the horns is just not as nice as it should be. The correct value resistor for each individual horn is the better way to go. Regards, Kevin.
