  5. Check motor operation by pulling connector and applying 9V with an external power source (battery or bench supply) to the plug. If the motor turns with reversed polarity then proceed by swapping black and red contacts leading to the motor. With a little flathead screwdriver press the contact spring, pull out the cable. If the motor only turns by applying external power and a little twist or not at all, only solution is to replace the motor. Mabuchi RF-500TB-12560 is readily available on the internet.

Many thanks!

I couldn't believe reversing polarity would work, but it did!

Yes, it's a miracle. :-)

If reversing the wires solves your problem then it was just a loose or poor contact at the switch causing the problem.

You are not switching polarity when swapping the wires. Like a light switch, it only serves as a connection/disconnection point for electrical flow.

Gibt's da auch eine technische Begründung dazu, warum der bloße Tausch der Motoranschlüsse den Fehler behebt?

Ich würd's nur gerne verstehen.
