i have a 1951 chevy 3100 with a original correct horn i found at a parts yard. it works perfectly fine when i manually short the contact to ground, but when i depress the horn button it only activates (the horn just clicks on/off not making noise). is a bad ground my issue? all the wires up to the horn button are fine but the horn button seems to be my issue. also i dont have a relay in the circuit, but since it works i dont think thats my issue.maybe take the steering wheel off and clean all the contacts? im out of ideas if someone would so kindly provide some insight. edit: the horn has a relay built into it, so thats definitely not my issue

I don't believe the original horn had a relay built in. It sounds to me like you have high resistance in the ground (horn button) circuit. You could add a relay to solve the issue, or track down the high resistance.

im calling high resistance on the ground end, because everything is new, therefore it could have a factory coating that negates conductivity. ill take the wheel off and wire brush all the contact points. its a start at best!
