To test if a starter is bad, first observe symptoms like clicking noises, intermittent starting, or no response when turning the key. For a direct test, locate your starter beneath the vehicle near the engine (you may need to consult your vehicle’s manual). Securely connect a multimeter to the starter's battery and solenoid terminals. Check the battery voltage; it should read around 12 volts. Attempt to start the car; a significant voltage drop without the starter turning indicates a faulty starter. Exercise caution and ensure the vehicle is in a safe, stationary state before performing these checks.
