horns

[theestimator]

Have a MK 2 Vitesse convertible and my problem is that the horns work independently but when both wired at same time I just get a grunt from the horn push - where am I going wrong

 

Thanks

i had this problem and found that one of the horns was faulty.disconnect one horn and see if the horn works from the horn push -if it does the other horn is faulty and vice versa.i took ages checking earths etc before i found the cure and replaced the faulty horn with one of fleabay.the other posisibility is a wiring connection  fault between the two horns.

good luck

It has the symptoms of a poor earth; good enough to pass the current for one horn but not enough for two.

Agree with John's diagnosis.

I ran with one horn for many years without realising it. I always thought I had a very woofly tone and it passed many MOTs to boot. I had both problems a faulty horn and inadequate earth.

A simple test would be to run a live wire direct from the battery to each horn in turn. If they both work then you have a wiring problem. If one or other fails then you have either a faulty horn or an earthing problem. This is easily overcome by earthing each horn directly to the chassis. Make sure it's a clean connection or it won't solve the problem. If both now work then it's an earthing problem, if not you have a faulty horn.

Once you've done all that you can sit back and enjoy the melodious sound of twin horns and so can your neighbours!

 

Cheers

thanks for advice given and must be a earthing problem as both horns work just not together as all I get is a grunt from front of car but as soon as either of the horns is disconnected we have noise
