So I've used one before the first gen they came out with but I wired it directly to the horn wires and it was okay. But this one I've been trying to use on my 02 twin cam. It's Hella loud when it works and sad when it doesn't. The relay clicks but horn no honky. I have put the stock horn wires on it and it works but is not as loud. I've tested and tested and seems like it decides to work when It wants to. The compressor reads 1 ohms when I put a meter on it, So I'm wondering if the compressor is garbage. 🤷‍♂️

 

Try replacing the relay

 

I did. I have a 40amp 4 pin and a 30 amp 5 pin. I set up a dry install with all the wires hanging out of the seat area and tested. And the compressor worked then after I tucked it all in it didn't. The relay clicks but the compressor isn't.

 

It's not rocket science. It's common sense. If ya fix it, modify it or change it AND it does not work, go over what ya did and look for what ya F'd up and correct it.

 

Did you contact Motohorn? No reason to bad mouth a company unless you've tried to figure it out with their help first. And if it works before tucking everything away, DUH.

 

You've got a bad connection. If it works when everything is out but not when you tucked everything in, that points to a bad connection somewhere. That's not Motohorn's fault.

 

I wasn't bas mouthing I ment it as i thought it was crapped out. Fortunately i did contact them, they said just connect the negative straight to the battery and it works. So I guess the negative post thats on the frame wasn't good enough.

 

no way it's motohorns fault. It worked fine straight to the stock horn connection but it's weak that way. I got it figured out by directing the negative straight to the battery.

 

MotoHorn has a F rating with the Better Business Bureau. Countless bad reviews, failure to respond etc. BUYERS BEWARE and companies should not sell this product as it will give them a bad rating.

 

He got in touch with MotoHorn and was able to get his issue resolved.

Sorry doesn't fit your narrative.
