Install The Electrical Component To Motorcycle

Let’s talk about a scenario where you wish to upgrade, or add an electricity consuming component on your two-wheeler. You need to ensure that your electrical system is competent enough to do it successfully. This may mean upgrading some or all of your electric components, and the upgrades will differ on a case to case basis.

Here’s what you need to keep in mind.


You need to read and understand the specs of the new electrical system first. For example, a new light system on your motorcycle will have a specific wattage and voltage. Here’s what it would mean:

Wattage – A higher wattage rating for any specific type of lighting system would generally mean more power consumed and more light emitted.

Voltage – Higher the voltage of the system, the bigger the size of the battery required. You should always have a thorough look at your two-wheeler’s manual to understand how much voltage can be supported.


You need to ascertain how much load you can put on your electrical system without overburdening it. A good way to figure this out is through the manual. So if your two-wheeler dishes out 400 watts, figure out how much of it is consumed without adding anything extra. You will have to add up the consumption of the stock headlight, taillight, and every other stock electric component. Again, consult the manual for a definitive number on this.

  • It’s important to note here that the power output of 400 watts mentioned above is at a certain engine speed. When the bike is idling or doing lazy speeds, the output is generally lesser. Always factor that in.

  • Once you have determined the total power consumption of the two-wheeler, you can subtract that number from our reference 400W number and see if the remaining output would be sufficient to power your new accessory. It is always good to keep a generous buffer here.

  • The easiest way to connect a new accessory with your electrical system is to power it directly from the battery, wherein its negative terminal connects to the negative and positive to positive. However, the accessory would now draw battery directly from the battery, which means if you forget to shut the accessory off manually when the engine is turned off, it would drain your battery. This problem can be solved with a power distribution block, which blocks consumption if the ignition is not on.

  • Another important aspect of an electric system is the fuse, which is meant to blow up to save the electrical system from a potential disaster when the current load increases to a dangerous level. So do not replace a fuse with one rated higher, as that would defeat the very purpose of its existence. Also ensure that there is a fuse in place for every new accessory, preferably closer to the power source.

  • Most decent electrical accessories would come with a manual, with all the details required before installation. Ensure that you follow the specifications and instructions in the manual before installation.
