/diy/ - Do It Yourself

Hey /ohm/ I bought a cheap rc car from thrift store, and I watched video here on reverse engineering rc car.

Couple of questions, so I have this circuit board

in the rc car

in the video I am referring to

he does continuity test, and when he touches the solder points the motor reacts. Mine however doesn't react when I try it, Mu multimeter read 4.5v when I touch the pins on sop, does that mean the motors are bad?

Here is the blog post I am reading.
