One more piece of advice. Never leave the battery selector switch in BOTH. If you do and have one bad battery, you will shortly have two dead batteries. Only use BOTH when one battery alone is not enough to start your engine. An exception would be when attempting to use the engine to charge both batteries. Also never put the selector switch to OFF with the engine running. You will fry the alternator diodes. Capt. George
