Section 8
Take care when connecting or disconnecting a battery charger. Be sure the charger is turned OFF and unplugged from power source when you clip ON/OFF the connecting clamps.
Make sure you have a solid connection with the charging clamps. Poor connections are common causes of electrical arcs and engine problems. Follow instructions.
DO NOT make or break electrical circuits at the battery terminals; a spark will occur when a live circuit is opened or made. Turn of all components.
Use a voltmeter or hydrometer to check the battery charge condition.
The battery cables should be removed from the battery when the boat is placed in storage, on display or in transit. This will eliminate the possibility of the engine accidentally starting without a supply of cooling water and may damage the engine.
