Kawasaki J300 - Service manual > DFI Servicing Precautions
DFI Servicing Precautions There are a number of important precautions that should be followed servicing the DFI system. This DFI system is designed to be used with a 12 V sealed battery as its power source. Do not use any other battery except for a 12 V sealed battery as a power source. Do not reverse the battery cable connections. This will damage the ECU. To prevent damage to the DFI parts, do not disconnect the battery cables or any other electrical connections when the ignition switch is on, or while the engine is running. Take care not to short the leads that are directly connected to the battery positive (+) terminal to the chassis ground. When charging, remove the battery from the motorcycle.
