Set the multimeter to the diode mode with a buzzer, connect the red probe to the negative pole and the black probe to the signal line using the rotary switch. When the resistance value is around 650, the rotary switch should be useable. Then, you have to install it on the electric ATV and power it on.

2.Check The installed Rotary Switch When The Electric ATV Is Powered On

First, set the multimeter to DC 20V. Connect the red probe to the positive terminal of the rotary switch and the black probe to the negative terminal (voltage around 4.5V). Next, connect the black probe to the negative terminal of the rotary switch and the red probe to the signal terminal. The voltage should read around 0.8V. Rotate the rotary switch, and the voltage will increase to approximately 3.6V. In this condition, the rotary switch is working.
