How do you check stator coil and cdi on a 185s atc?

To check the stator coil on a 185S ATC, use a multimeter to measure the resistance between the stator terminals; consult the service manual for the specific resistance values to ensure they are within the specifications. For the CDI, you can test its functionality by checking the input and output voltages while the engine is cranking; a lack of spark may indicate a faulty CDI. Additionally, inspect the wiring and connections for any signs of damage or corrosion that could affect performance.
