HI Sobin and welcome to Ninjette!

This thread has numerous suggestions, but not the 100% sure way to find this issue. That requires these two items.

First is getting factory workshop manual for this bike. The wiring-diagram will give you map of circuits which can be used in troubleshooting this problem.

Second is to get multimeter and learn to use it to measure voltage and resistance (perhaps also current):

Link to original page on YouTube.

Once that's done, you can measure resistance between various parts of system to find short. You can back-probe connector to touch terminal of these wires.

1. measure resistance between battery negative-terminal and WHITE wire leaving starter-solenoid plug. What resistance (ohms) reading do you get?

2. measure resistance between battery negative-terminal and BROWN wire leaving ignition-switch. What resistance (ohms) reading do you get?

Repeat above measurements while wiggling harness gently between battery and ignition-switch. Go 20cm at a time and travel towards ignition-switch. Then from ignition-switch to fusebox. At some point, multimeter readings will change. That's most likely where short-circuit is located. Could be frayed wires rubbing on each other or frame of bike. Might need to unwrap harness at that section and take closer look.
