When charging pocket razor with a car battery charger were do i connect cables n my scooter

I haven't used my razor scooter in years. I just bought a charger and it seem like it is charging but it keep saying it is on low. I twisted the gas thing and it is making a noise like it want to go. But I am not sure I have charge it for 12 hours now. Do I need a battery or is it just taking it time to charge.

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

You can download a manual from Razor here...

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.

MOST LIKLEY BATTERY THEY CAN ONLY BE CHARGED LIKE 3000 TIMES OR SO

CHANGE CABLES TO BATTERY

yes sounds like the control module, you can always jump the batteries directly to the motor to make sure that the motor is ok

one or both of the batteries must be bad, lift the seat up the remove the screws that hold the compartment down and then you should be able to see the two batteries below there, first visually inspect the batteries to see if they look like they are bulging, then test each battery with a multimeter and make sure it is showing at least 12 volts, chances are one or both of the batteries will not show more than 12 volts

check the charger end with a multimeter and make sure that its showing that its putting out the correct voltage

Signs of the Razor Bistro battery needs replacing.

Depends, some tabs are directly soldered to the batteries themselves so you will need a soldering iron to remove the tabs. After that, it wouldn't be too hard to remove and replace.

Keep in mind that these take 2x12volt batteries and these lead-acid type batteries may take a long time to charge depending on the current your charger is supplying.

If you plan to charge the two batteries with the stock charger, then you would have to wire the 2 batteries in series for 24volts (stock charger 24v) and for convenience you may also want to head out to your local electronics store to see if they have the female socket that the charger goes into, and possible some wire, connectors/tabs that attach to the batteries and possible some small alligator clips if required.
