720 Horn location

OK.

 

I KNOW I'm going to get flamed here!

 

Pls tell me where the F$%^ing horn on the 720 is.

 

The only place I havent looked yet is behind the bumper bar.

 

Thanks for being gentle.

Generally below both the low beam headlights behind the bumper, on the front of the rad support. (I spit on it first)

Thanks guys, I am such a noob I know.

 

FWIW I did half a search :)

[datzenmike]

Ah I see Draqker had you first.

If you were younger you could push the bottom and run around to see where the noise would be coming from.

 

 

Just sayin'.

Ow, age jokes, that hurts!

 

Been pushin the button, but no noise making happening.

 

Thanks to all, now the horns have been located, just need to pull the fucking bar off to get to them.

 

Stooopid Datsun engineers!

You should hear a clicking sound from the relay. The chance of two horns quitting at the same time is very remote. Check the 11th fuse over from the driver's door. It powers the horn and the chime and nothing else so you won't know it's not working. The horn relay is located under the dash beside the steering column (probably the left side in Oz) but next to the intermittent wiper amplifier box. If no click maybe the horn butten is not grounding. I rarely use the horn and sometimes it fails to make good contact. Try honking on it repeatedly to clean the contacts.

Thanks Mike, good trouble shooting. The relay was going to be my first thing to find as it definitely isnt clicking.

 

I might start at the steering wheel and work forwards.

[datzenmike]

I'd try the fuse first if for no other reason than it's easier to get at.

 

If OK, bump the horn 50-100 times to clean the contact of pull the cover off center of steering wheel and clean.

In my work I talk a lot about circumstantial, and actual evidence.

 

No oics, but, interestingly enough, the battery had an earth cable grounded from the body (back of the battery tray) to a line which terminated where the negative battery terminal is, but, someone had hacked off the connection meaning basically, no earth/grounding.

 

So, circumstancial evidence suggests, despite most of the other electrics working, actual evidence suggests lack of battery to body/chassis ground MAY be causing a problem?

 

Connection of said eart/ground wire now results in horn(s) working.

 

Who would have thunk it?

Source, load, ground.

 

 

Nissan having a bad ground? No way. Not buying it.

^^^^ yeh I know, crazy talk from me.

 

Im just happy that the damm things are working.
