Battery_Operated_Toys_CarIn this post let us discuss about how to resolve the problem in a china made battery operated Toys car.

If your child's battery operated toys car/bike is not working, we would like to recommend to do the following steps one by one.

You need basic tools like screw driver set, basic multimeter.

  1. Check the charger.
    Connect the charger to the mains, turn on it. Using multimeter at the output pin check 9V is coming from the charger.
  2. If the charger is ok, then the problem will be inside the car. Open the plate which covers the PCB, battery etc.
  3. The common circuit flow for all battery operated vehicles are as follows:
    [1] Convert the 230V AC into 9V ( which the external Charger does)
    [2 ]Send this 9V to the controller PCB
    [3] From the controller PCB wires will go for battery, motor, any headlights (depends upon the model)
           6V, 4.5Ah battery  has been connected to the PCB.
  4. Check for any loose contacts. Ensure that the wires are properly connected to the battery. Due to rough use by kids, some times it may get loose. Fix it rigidly and once again charge for some time. Check whether the problem is resolved.
  5. Using multimeter ( Continuity mode) check the continuity of the wires connected from controller PCB to battery.
  6. Check the voltage across the battery during charging condition. The voltage should be around 7 during that time. If not, it is not getting charged.  The problem might be inside the controller PCB.
  7. Check the voltage across the battery after charging for some time.
  8. If the voltage is still less than 5.8V even after charging for  a while then the battery might have gone bad. Replace the battery. It is available in the market for around Rs.200/-
  9. In the controller PCB various functional blocks are available like
    [1] Battery charging part
    [2] Relay circuit part for giving initial high current to the motor
    [3] Programming part to store the music etc
  10. Check the continuity in the battery charging part.
  11. Sometimes if you use 9V, 1A (9V, 500mA rating charger is the right choice for 6V, 4.5Ah type Lead Acid rechargeable batteries)  rating charger some of the soldering may gone bad. Identify that and do soldering.

    My son's 12v AMG drives ok but when he takes his foot off the acceleration pedal the car continues to move for a few more seconds / feet even though taking his foot off the car should (and previously did) make the car stop. The same issue occurs when using the parental remote control. The car was previously working fine... All other features are working as normal. Any suggestions would be greatly appreciated. Thanks

  17. Sandeep says:

    By using remote we push right button but car is going left and by pushing left button in remote the car is going right....

  21. Gemma says:

    Hi. My cat decided to wee inside the car. I have charged the car and it won’t drive in manual or rc mode. The sound and lights are working. When I try to activate any form of movement it restarts the car temporarily shorting lights and sound. Any help on what to do please.

  22. Lee Molyneux says:

    Hi I have a ford ranger 12v for my son. It cuts out when he tries to drive at the faster speed setting,but it works at the slower speed setting (which is a snails pace). The faster speed setting is fine when the accelerator is pressed while the car is on a stand without him in. I have changed the motors and gears on both sides because the original ones burned out. Help!???

  23. Cheryl says:

    The left / right turn doesn’t work just forward and back while ysing the remote control on the yahoo
