Wolo BB horn...10A fuse OK?

[SedonaBound]

Has anyone with a Wolo Bad Boy horn had a problem blowing the 10A fuse in the factory horn wiring? The Wolo instruction say just plug it in, but the diagram shows a 20A fuse. Also, did you try connecting the OEM horn in series?

Had a similar horn with the canister compressor. I had to put a relay in to avoid putting in a higher rated fuse. I left the stock horn off. This way before I put in the air horn I have now.

I'd run a relay.

I'm not clear on this because the OEM horn is already on a relay. Did you add a second relay on the horn connection with a new 20A fused wire from the battery?

Yep. Used the leads for the stock horn to trigger the relay. Kinda redundant but much easier implement.

I will ask a couple of the member that I know who has the Wolo on their rigs.. I will see what they did and post it...

I just put one on last weekend spliced into horn wires. Both horns are energized and it immediately blew the 10 amp so I replaced it with a 20, all good. Pretty sure thats the same thign Mutaint did as well.

So you left the OEM horn on the circuit and both horns are now on the 20A fuse? Have you given it a few really long blasts? Did the wires get hot?

I was hoping the diagram was generic for all their products and the specific horn current was lower. I called Wolo and they advised that I just change the fuse to 20A. I haven't decided whether I'll do it that way. I'm going check the installed wire's gauge & length first.

 

[GoBlueHummer]

Yes the OEM is on the circuit as well. No I haven't tested it for any longer than I would normally blow the horn, 5-6 seconds.

I hooked it up on the existing wires and changed to a 20A fuse. Thanks to all for the advice. Disconnected the original; it didn't sound any better with the new horn than before. Hardest part was taking the cow catcher off; the tow shackles prevent putting a socket on the bolts so its 1/2 turn at a time and they're looong bolts.

I don't think it makes much difference having the OE horn on as well. It's fairly close in tone to one of the Wolo tones it off later. Maybe swap it out with the horn on my wifes car whcih is deafening. :shifty:
