2 wires per horn.

I have a 12v battery. I hook 1 horn up and to BLOWS. Same with the other. Black to black to battery and white to white to battery and they just rumble. NO BLOW. hoq should i test wire?

weak battery?

Are you connecting series or parallel? Troy, I just had a funny image of a 12v battery with the amps to power a toy. Tell us about the battery?

I guess it could be the amps. It is a 12v drill battery.

ok um ya ..... a car horn draws up to about 10 amps


ever notice that the horn circuit has a big fuse?

Well.... when I.suspect that the battery is dead I try to blow the horn. This test never fails.
The horn is one of the most power demanding things in the car.

So today the test moves from the bench to the watercooled VW, close to the bench. I'll use that battery.

Thanks gentlemen.

That was it. They are plenty LOUD. next time i take my bumper off, the new horns go on.

If I remember correctly, the horns can be changed thru the fog light openings.
