How to check and fix a toy electric car ! 

Mini -Tesla!

😀

Check the motor's connections, also if you have two batteries , check if they are properly connected, maybe a loose one..

I believe they have a cut out fuse that operates if under too much torque then re-sets, to prevent motor or battery burn out

Multimeter in OHm meter and diode mode, listen the beep.

It's looking like a Mosfet or relay in short..just follow the wires from the motor up...

But check the switches 90% of problems derives from there..just take out the one for gas..see if the car is stoping..replace or clean it

You need loaded batteries. Check the charger with multimeter for voltage..maybe it's not delivering anymore..also consider to charge the batteries from another charger..even from the car battery with some wires..be careful about polarity!!

It's an extra minus wire, going to different modules depend of the model, let it in the air. You have to check with a multimeter 12V path, from input to battery first. Check the battery voltage and apply power..the voltage should go up slowly , it's charging. Next check the path from battery to self reseting fuse, then switches and finally motors. 99% are the switches, so open and clean or replace.

Like I said, the switches are the problem..open and clean, or replace..

Hope you fix it!

That starting/radio/layer sound is got nothing to do with the motion part..for that you should check the loudspeaker. I bet you need to clean the switches..

@@viocaia okay thanks ill give it a go

There is always a beginning ! There are plenty of tutorials about how to use a multimeter..and it's fun too!!

check the connections to the motors first, I found one loose.

How can I help you? I'm in Romania for now

I don't see any models with a proper accelerations ''gas'' feel..tehre is no pressure sensor, it's simply non/off switch...the low/high speed it's controllable from a second switch on board , probably that one is shorted..usually at low speed the motors are connected in series and at high speed in parallel..somehow it's stocked with parallel...check that switch..

It's looking like a loose battery..or a lack of charging..try to charge with external car charger first..if it's alive, that 's a solution, butI believe the battery is gone

Hey! You should start checking the batteries.maybe they don't keep a charge or something wrong with charger..but from my experience, 90% is switches problems..

@@viocaia I will try there. I will come back and tell you how it go. thank you 🙏🙏🙏

It actually worked !!!! . God bless you! you saved me 350$ I was planning to buy another one 😀😀😀😀😀

@@pahola54able Glad to hear that!!!

The sense switch is the problem, open and clean the contacts..or replace it.Another idea is to switch the terminals and let it run only forward until you find a replacement.

Check the bateries, connectors too, go to main switch

just bypass the fuse..but I'm sure the problem is the switch..90%

@@viocaia thank you so much i change all switches and car is working now sir thank you so much sir

@@sudhirnanaware2811 Nice! Happy to help!

Yep! They are not cheap too..it should be more resilient..but where is the bussines? We do the best for our kids..no?

Multimeter on continuity mode or simply a bulb and a battery..get the fuse in series

Thanks

Hope it helps!

Serious? You wanna still my electric?..joking..🤣 Search for the plus..with multimeter and use a piece of wire, strong enough and short the switch..but it will be on al the time draining the batteries..better try a switch.any..and replace it..

@@viocaia thank you sir.

Check those switches first, those are prone to get oxidation

Plug a car lamp 12v5W instead of motor and do run command..if it lit the motors are the problem..I doubt that..if is not lit, check the relays..if any or the control MOSFET follow the power route..

Why?...I like to fix all kind of crazy stuffs! and it's fun too!

Dear Mexicano, please subscribe for more ...

First check if the motors are ok, just connect two wires from the batteries to motors..they should move.About wirings they are pretty standard, just google for a schematic..A multimeter and soldering is a must!

Which wires did you disconnect? The gentleman is doing a complete overhaul here. Family people can Isolate the issue easily. All electronic parts are replaceable. (Motors, music, starter, fwd/reverse, steering wheel, independent swing, remote motor) The only wires requiring you to undo is the motor connections and everything else you just undo to put in a new part (use exact same connections it had previously) The battery wires. If you have single 12.7v battery then red to red and black wire to black battery terminal. If you have 2 X 6.45v then 2 black go to 2 black battery terminal 2 red go to 2 red terminal. There is a small black fuse box. That can be replaced and the 2 wires just go back in The motherboard, they all just click back in. Just match up the size to the hole. I can't think of what other wires you may have . Nor do I know an easy way if helping you via photos because we're in a comment section here Most important. Please don't stress. With someone helping you, They're incredibly easy and made for everything to be replaced apart from all the lighting wiring. (Although can be done) This gentleman had done everything technically and he even lost me
