Anyone know what the resistance should be for TR4A horns? The reason I ask is that I keep blowing the horn fuse which is 20 amps. I am getting 0.8 ohms across mine which works out to 17.25Amps @ 13.8V. That seems like it’s a bit close to the fuse rating to me. I am not sure what else could be the problem.
