I'm trying to measure current to a DC motor on an RC car I took apart. The car is powered by 3 AA batteries and seems to be made of three different boards. Two of the boards are for switches and LEDs, the other is the main one in this shot that I'm trying to measure so I can replace it with my Arduino.
I am trying to measure the amperage to the motor, as well as that motor in the back of that shot. I have tried using my multimeter on 20mA, 200mA, and 10A with no sensible reading and it always stalls the RC car.
Shouldn't I be able to get a reasonable result?
Edit: All the pictures I have of it are in this page
I've tried connecting on the motor directly and on the wires leading to it both before and after that capacitor.
Edit: Thanks again for the help everyone. I'm going to give it another go soon and post some pictures of the configuration once I get it going
