E20 razor rocket electric scooter will not charge and someone said you need to insert a fuse but it doesnt tell you were or how. i have only purchased this as a christmas present for my daughter but it does not work. i have tried to charge it for hrs but to no avail.

The battery has probably died. Use a voltmeter to determine what voltage is in the battery. If you don't have one, take it to an auto electrician, he will be able to tell you if the battery is dead or not. Most batteries only last 2 or 3 years. Check if there is enough water in the battery. Use distilled water. If its a "non serviceable" battery , you will only be able to test the voltage. The sticker on the battery will tell you if its 6 or 12 volt DC

No. The switch should be off before connecting the charger.

I think you can a new dirt bike charger easily on Amazon or on the razor website. Be aware of how you use the battery though, it is the same idea for a lot of mobility equipment (electric scooters, electric wheelchairs, electric bikes, and etc...). You need to use the battery PROPERLY. For example, charge them from time to time, don't leave them there for a long period of time just because you don't need to ride out your electric dirt bike. Your battery's longevity will get hurt. Also, protect it from water and dust. I learn a lot more about outdoor sports equipment on this site: https://mobilityseeker.com/.

You use the supplied charger, or if you got it used without a charger, you can buy one here: Replacement Razor Pocket Rocket PR200 Scooter Battery Charger Adapter... After that, you plug the charger into the wall securely, and pull down on the round cover next to the motorcycles power button until it opens. Then plug the other end of the charger into the motorcycle.

razor hasnt been charged for a week as i needed a new charger i had 1 scooter charging over night yet still nothing , i bought a new charger its showing green on the light do i have to wait till it shows red and then wot if it doesnt still work

Take it back and get an exchange one. Or, manualy check fuse, check wires conected to throtle and motor. If it all looks ok then its most certainly a wiring fault

Come on man....E100.

it wont charge because the batteries need to be replaced.

have you tried to push the scooter like a normal non-electric scooter then while moving twisting the throttle? If not, then i dont know what to tell you except to get a new one.

get a new battery
