[Fot] TR4A Horn coil resistance

[Dave Connitt]

Well, I thought that too but I measured the coil resistance after disconnecting them from the rest of the circuit.

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.
