Pom Pom, Peep Peep.
A familiar sound on the Road. A device given in your car to get attention of the people in surroundings to yield way for you to pass.
The Horn.
Although I detest using it unnecessary in the city runs, it's one very important device on the highways specially on the ghats to intimate oncoming traffic on the blind turns.
Well, most cars have a pair of Horns that sound at a little different pitch. The combined pitches creates a good loud sound enough to tear through the surrounding Noise and make a mark.
But if you listen to the sound of a single horn separately, its too low and ineffective.
Even for a car like Safari with one Horn gone Kaput, The single horn literally feels like that of a Scooty .
In my recent trip I had to face a similar situation. One of the Horn stopped working and with the Single Horn it was too frustrating and embarrassing to sound the it on the curves.
Somehow completed the trip safely without any issues.
No use of the car for the next 3-4 days and then on Monday had to travel to Pune from Mumbai.
Expressway is good enough to not require a horn.
In the evening thoughts are running about the horn. What to do? Go to the garage and get it checked or try on own.
Lately have been doing a lot of DIY at home as well fixing few electrical/electronic things. The wave is still alive and I decide to give it a try.
Before We move further on what I did to rectify the horn of my car lets have a look at a Videos to understand the working of an Automobile Horn.

So from the Video what we understand is the horn creates the Sound by continuous vibration of the Diaphragm.
For the Diaphragm to Vibrate it is continuous pulled and released by an electromagnet.
The pull by the electromagnet causes the contacts of the circuit to break and disable the magnetic field and release the Diaphragm. This allows the spring loaded contacts to connect again enabling the electromagnet to pull the Diaphragm again repeating the cycle.
This remind me of the Door Bell working we learnt somewhere in Class 5 or 6.
From the above inputs below are the probable reasons that would make the horn stop working.
1. Coil creating the electromagnetic field getting damaged.
2. Connections to the coil from the external leads getting damaged
3. Ruptured Diaphragm
4. Broken Spring loaded contacts
5. Oxidised Spring loaded contacts not allowing the Current to flow through the circuit.
