I'm thinking my horn relay is not working, can someone please explain to an electrical idiot how to check mine?
Lower right is red, I'm assuming hot all the time.
Lower left is black, I'm assuming ground.
Upper left is green, I know goes to horn.
If I put power to just green wire, I get sound.
My assumption is...If I put steady power to lower right, hook up jumper from upper left to horn wire, then ground lower left, the horn should blow. Yes/No?
Yes you would be correct. If you just put B12 on red and touch N12 to relay you should here it click as it picks up. Then there will be 12 volts on contact to horn. Of course horn needs to be grounded

Thanks,
Horn is grounded. If I put power to just the green wire, the horn beeps. No matter how I try it, relay does not click.
