Horn Issue

[GolfVenture]

I installed 2 sets of Stebel ELectric horns. I used the exiting 2 sets of wires, Left wires for the front set and right for the rear set. Each set has its own relay. The horns have been working for several months. This last weekend during an hour ride it seems that the horns were not as loud. When I got home I press the horn button 4 times as I touched each of 4 the horns. The rear horns does not work. I took both of the rear horns off and wired them directly to the battery and they work.

 

I put a new relay on and still does not work.

 

I would like to start troubleshooting with the 4 wires at the relay, only I've forgotten what wire goes where.

 

Could someone fill in the blanks for me

 

30 comes from where ____________

 

85 comes from where ____________

 

86 comes from where ____________

 

87 comes from where ____________

 

Thank you.

30 the battery

87 to the horn

85 to ground

86 to the horn button

So I could use wire from 30 and wire from 85 and hook them to the horn.

 

If Horn does not work then I can run seperate wires to the battery and figure which wire is bad 30 or 85.

 

If it does honk then the problem is 87 or 86. I could run a new wire for 87 which would determine which is bad 87 or 86.

or you could use a test light or a volt meter and test all the wires at the relay in about 30 seconds.

Daaa you so right.

 

With a test light

 

1) 30 Battery use a test light to the Negative battery

2) 85 Ground use a test light to the Positive battery

3) 87 Horn use a test light to the (negative battery) is that correct?

4) 86 Horn Button use a test light to the (positive battery) is that correct?

4) 86 Horn Button use a test light to the (negative battery)

 

86 and 87 should light up when you hit the button.

 

If 86 does not light up, then there is a problem with the wire between the relay and the horn button, maybe the factory fuse...

 

If there is power at 30 and 86 lights up when the horn button is pressed and 87 does not light up when you hit the button, then the relay is bad. If 87 does light up, put the tester on the wire at the horn and see if it lights up, if not, then the wire from the relay to the horn is bad.

4) 86 Horn Button use a test light to the (negative battery)

I will try this in the morning.

 

86 and 87 should light up when you hit the button.

Do I connect to the negative battery?

If 86 does not light up, then there is a problem with the wire between the relay and the horn button, maybe the factory fuse...

The front set of horns work so it wouldn't be the fuse, so the wire between the relay and the horn button.

If there is power at 30 and 86 lights up when the horn button is pressed and 87 does not light up when you hit the button, then the relay is bad.

I put a new relay on with same result, horn still did not work.

If 87 does light up, put the tester on the wire at the horn and see if it lights up, if not, then the wire from the relay to the horn is bad.

Do I ground the other end of the tester to ground?

4) 86 Horn Button use a test light to the (negative battery)

 

86 and 87 should light up when you hit the button.

 

If 86 does not light up, then there is a problem with the wire between the relay and the horn button, maybe the factory fuse...

 

If there is power at 30 and 86 lights up when the horn button is pressed and 87 does not light up when you hit the button, then the relay is bad. If 87 does light up, put the tester on the wire at the horn and see if it lights up, if not, then the wire from the relay to the horn is bad.

 

 

So I wasn't able to understand the above instructions fully but here is what I found out.

 

First A quick summary - I have 2 sets of Stebel electric horns. a Front Set and a Rear set. Left origional horn wires to Rear horns and right origional horn wires to Front horns and both front and rear horns has their own seperate relay. The horns has been working for several months and now the rear horns stop working.

 

This mornings test results with a trouble light

 

1) With key off, connect to + battery and to 87 the rear horns blow good.

 

2) With key off, connect to - battery to 86, no light.

With key on, connect to - battery to 86, yes light

 

3) with key off, connect to + battery to 85, the front horn blows.

I'm thinking this is ok for the 2 origional sets of horn wires work together.

And so power is being fed directly from battery to both horns.

 

5) 30 being power, with key off no light.

30 being power, with key on it lights when I hit the horn button.

 

Remember that the Front horns work like it should.

 

Any Suggestions?
