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

It is applicable for the middle order bikes with kick start (Most common in India)

Hello Sir,
I would like to know if it is applicable on Royal Enfield Standard 350 cc Model as well ? Since it Does not start without battery being connected or when battery is low(although it doesn’t have self-start option but even kick start is still dependent on Battery for this variant)..I would love to get rid of such dependency on battery for my motorbike,since it would relieve loads of hassles for me.

I have not tried this for Enfield. You can try this, it will not harm your bike and not a costly experiment too. Use two to three capacitors in parallel, I think it should work out. Try and post your result, it will be helpful to others also.

Hi, I’ve tried with Capacitor of rating 2200 µF / 16 Volts for my H.Honda Glamour. Horn is working fine when engine is accelerated, but when in normal running (just start) horn is not working. Indicators are not working in either above cases. Please guide me what to do. Thanks.

Try with more capacitors (at least 4) in parallel . I think the power required for horn and indicators of HH Hlamour is more.

No friend,
The case of car is different. No such technology developed till now. Car battery is used for starting also na? No such capacitor is available to deliver such an amount of energy.
