Circuit board of Carrera RC Turnator


The teleremote car of my kid stopped working (Carrera RC Turnator). Opening it I found a wire was loose between the backside and the front of the circuit board. On the pic you can see a little white wire that’s loose from the small circuit board. I’ve tried connecting it to many parts of the motherboard, but no succes.

Anybody has an idea how to fix this? Thx!

Hi @zwoane ,

If the toy has no external antenna, that wire looks suspiciously like an antenna wire and it should only be connected at one end. WiFi antennae are only a short length.

Have you checked the batteries / battery terminals etc, in the controller and toy?

Was this answer helpful?

The toy indeed has no external antenna. I just figured the wire needed to go somewhere as I didn't see anything broken or so… so probably has nothing to do with this wire or with the circuit board. Battery seema ok as well, but it just doesn't do anything ;/

Thx a lot!


Hi @zwoane ,

Not sure if this will work but if your RC toy works in the 2.4GHZ band (WiFi band- a lot do) you may be able to use this app to check if there is a signal being sent from the controller to the toy when you press the buttons. (That is if you have an Android phone - don't know about iPhone perhaps there may be an equivalent app.

As I said not sure if it will work at all but the app is free so all that you've lost is a bit of time if it doesn't detect anything coming from the controller.

If you can detect the signal then at least you've eliminated the controller as the problem and can concentrate on the toy vehicle.

Alternatively you can build your own
