If your motorcycle is making a clicking noise even with a new battery and the ignition disconnected, there could be a few possible explanations:
Starter Solenoid: The clicking noise could be coming from the starter solenoid. The solenoid is responsible for engaging the starter motor when you try to start the motorcycle. If the solenoid is faulty or worn out, it may produce a clicking sound instead of engaging the starter motor.
Starter Motor: The clicking noise could also indicate a problem with the starter motor itself. If the starter motor is not receiving sufficient power from the battery or if it is damaged or worn out, it may produce a clicking sound when you try to start the motorcycle.
Loose or Corroded Connections: Check the battery terminals and other electrical connections to ensure they are clean and securely fastened. Loose or corroded connections can result in a poor electrical connection and cause clicking sounds.
Faulty Relay: Some motorcycles have relays that control various electrical functions. If a relay is faulty, it may produce clicking noises even when the ignition is disconnected.
It's recommended to have a qualified mechanic inspect your motorcycle to diagnose the exact cause of the clicking noise. They will be able to perform specific tests and checks to determine the source of the problem and recommend the necessary repairs.
