I charge the batteries over night and after 3 hrs they go dead charger is reading 24 volts but at battery end is reading 18 volts new batteries so could it be 30 amp circuit breaker
Bad connections on the battery posts is most likely. If the circuit breaker was bad you'd get nothing at the battery . The charger voltage is 29 volts when not connected to the batteries. 26 or more when connected and on.

The chargers are expensive because they are a 24 volt, 4 Amp charger. These scooters use 2 x 12 volt batteries and provides power to one (or two) 24 volt motors. Disconnect the batteries and check the voltage of each battery and check the output voltage of the charger.
Possible suspects are:
1. A severely drained battery.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.
hi, okay now does this happening every time ? or is the distance variable ?
check the batteries are fully charged, if possible check the batteries with a electrical meter when it stops again , insert the probes in the charger socket the outside ones , the middle on you can ignore , check the voltage , below 23 or 24 volts this means that once you start going again the voltage will drop causing the controller to cut out , they normally cut out at about 18 volts .
Satisfied that's okay now the brake could be breaking down ? do you hear it click when going along ?
hi, you say the voltage is 3 volts each, then it never work , remember it's requires at least 18 to 20 volts to light up.
if a battery measure's below 10v it's normally impossible to charge again as a lot of chargers will not go below this level, you could try a car battery charger to bring the level up however do this with care and don't leave on charge Regardswww.gewizrepairs.co.uk
18 volts is not enough voltage to run this scooter. You have 2 batteries that should each read a max voltage of 13.5 volts each or 26 to 27 volts when fully charged and measured in series. 2 batteries that are 50% charged will read 24 volts. Your batteries are almost dead by this measuring method. Charge them up or replace them and your scooter should run. Hope this helps.
Blue Positive Brown negative, Yellow with green stripe is additional ground. many people are trying to use the 2904JT charger for a 24 volt charger for other things. I am using mine on an e bike that has 4 12 volt batteries. I charge them 2 at a time and it works well. It only shows voltage when the batteries are partially charged. Some kind of safety feature to keep you from charging a shorted battery. No schematics available, I took my chances and verified the Blue wire is positive. lol Good luck with you project or re wire. : )
This concern will require a volt/ohmn meter. If I am not mistaken, this scooter requires two 12 volt batteries wired in series. That is, the positive post of one battery connects to the negative post of the other and vice versa. This then constitutes an operational voltage of 24 volts. On most scooter chargers there are 3 pins that plug into the scooter to charge the batteries. On mine, the pin in the center pin is "ground". However, it is easily identified by setting the voltmeter to ohmns reading (a horseshoe shaped symbol) and doing what ever dissassembly is necessary to reach the scooter side wiring then touch one lead of the meter to either of the negative posts and the other to the exposed wires until the meter reads 0 ohmns or very close to this. This is the charger ground. Then set the meter to read DC voltage. Disconnect the charger from the scooter. Place the black lead on the meter on the identified ground of the charger and the red lead on either of the other two leads. There should be 12 volts either location. If there is not. the charger may be the problem. If there is, the batteries could have an internal problem and any auto parts store will happily check them for you. Good luck and good hunting.
