I wanted to be able to switch off the train horn installed in my truck and use the steering wheel for the stock horn or the train horn. I installed a latching switch and am switching the ground to the train horn solenoid. The positive wire going to the solenoid is spliced into the wire right where it feeds into the stock horn. So now both horns go off when switch is on, only stock horn goes off when switch is off. My question is.. will the solenoid on the train horn be a problem for the circuit and overload it blowing the fuse? The stock horn has a 15 amp fuse. The train horn recommends a 5 amp fuse but currently is just running off the same fuse as the stock horn as mentioned. Is this ok to leave it this way? Any possible issues? What is the correct way to do it if so? Thanks in advance for any help!
