Is there a fuse, under the floor, on Boreen jia electric scooter

SEARCH FOR A LOCAL DEALER .

Know this is an old post but if someone else needs to know how to get to the batteries on boreem jia remove the nuts at the bottom of the shaft holding the seat where it connects to the fiber glass frame and then remove seat and shaft and then four nuts "2 on each side" under the feet rest, you may need locate the tops under the boreem label by peeling it back to hold while untighting that's it, now you can slide the housing to the side be careful of your wiring only enough room to access and remove batteries. You will have to either cut or use soldering gun to free up the wires hope it helps

Pride scooters often have fuses that are not shown in the manual. These may be located under the central floor mat hatch.
The charger may be faulty? It happens.
If not that, I recently purchased a faulty XLR plugged charger cable. The man who was selling them hadn't got a clue! Everything was cross-wired! That fried my floor fuse.

Try the Charging circuit fuses hidden under the mat and floor hatch.
Is the charger OK?
Are the batteries coming to the end of their life?

Hidden under the floor mat and hatch, you'll find two high amp fuses that Pride say don't exist! - they do. Be careful with the rubber mat lugs they deform and are tricky to reseat.
the fuses are standard car fuses. It's busually the red 10 Amp fuse that's blown.
the cause of the problem may possibly be the three pin XLR cable/ plug.

black is negative, red is positive to controller, yellow is ignition on

I too have a problem with a Jia 601s in that I have the owners manual but replacement parts do not match existing scooter
