when I installed it as per the guide and push the horn button, it drains so much power than the lighting of the dashbord and the lamps starts shaking and yet the horn sound is weak as if it does not receive enough power...
the description of the item says it is suitable for both 12v and 24v...I contacted the seller and yet I'm waiting for his response...meanwhile I don't want to think that I paid 53 USD for nothing :S
my battery is still almost new and tested the voltage which is within the normal level.
I see...so if the current is not isolated from the button switch this will cause the interruption in the sound...probably I should take it to an electrician to install it again and see...
the horn is substantially big...and the video test made it look compact and I loved the high tone...but I thought since it is 12v it should be ok....I will give it a second try through my local shop..
If the horn is not isolated from the button switch with a relay, you can burn out your horn switch, which would result in no power at all to the horn... You did wire it up as directed with the supplied relay.
Yeah I saw your instructions calling for using the stock relay to power their supplied relay, which is fine... The Euroblast horn just has too much current draw, and/or is a piece of crap, unfortunately.
You need to wire directly from the relay teminal 30 to the + battery terminal with 12 ga. wire, then with the same wire from terminal 87 to the horn. Your original horn wires go to terminals 85 and 86.
Use a 20 amp fuse in the line from the battery to the relay.
