The battery of motor cycles are usually used to power horn and indicators. If you are not using the bike regularly, then  the battery will be under charged and get damaged easily. Here on simple technique to power the horn and indicator of the bike.

For this you need to purchase one electrolytic capacitor of rating 2500 micro Fared 16 Volt (More rating can also be used). This is available at all electronic spare parts or repair shops for approx Rs 15/-

Remove the faulty battery and connect the capacitor’s positive lead to Red wire and negative lead to black/ green wire. The lead identification of capacitor is as show.Aluminum Electrolytic Capacitor 300x300 Run your Bike without Battery

Now start the bike…Your bike’s horn and indicator will work. This is tested with Hero Honda, Bajaj and TVS bikes.

    there is another option.battery may get weak due to many reasons.one reason is less use or keeping it idle for many days. buy a small switch suitable for bike and car,connect it in the negative wire,if needed use additional wire too ,fix the switch comfortably somewhere.

    if the battery is weak or reported dead—————–

    its a serious problem which may cost u 2000 rupees.
    dont worry.
    remove the battery.first top up the battery with distiled water.charge it with a battery charger.12v charger.check voltage with multimeter.its simple.multimeter can be of 120 to 1500 rupees . battery charger can be assembled or can be bought with 100 to 300 rupees.
    if the battery fails to revive,dont worry open the cap carefully remove the plates ,with a tooth brush ,brush and rub the plates ,clean it.add good electrolite,water etc.
    charge it again .

    alternatively take that battery to some local auto electricals,battery centres or electricians he can fix it and revive that battery.
