Looking at the user manual....
The battery is under the seat at the rear. A black plastic cover has 3 Philips head screws.
The fuses are beside the battery... (to the right side).
the fuses have a separate rectangular cover...
Not sure if the fuse cover is under the battery cover or beside it.
The headlight fuse is #5, marked H/L, a 15 amp fuse.
Not sure what #6 is, marked in Chineese.... may be a spare
Remember to use the correct size fuse, not a larger one unless you want a chance at a fire.
Scoot safely,
