Checking Before Start-Up
Check the battery charger for proper operation. If the batteries are properly charged, the needle of the ammeter will register near "0" (zero).The battery charger must not produce excessive current during start-up. Alternatively, the charger must be automatically disconnected for start-up. If the engine has an alternator, the charger must be automatically disconnected during start-up and during engine operation.Charging the Battery
Never disconnect any charging unit circuit or battery circuit cable from the battery when the charging unit is operated. A spark can cause an explosion from the flammable vapor mixture of hydrogen and oxygen that is released from the electrolyte through the battery outlets. Injury to personnel can be the result.
Perform the following procedure to charge the battery:
Ensure that the charger is turned OFF.
Adjust the voltage of the charger in order to match the voltage of the battery.
Connect the POSITIVE "+" lead of the charger to the POSITIVE "+" battery terminal. Connect the NEGATIVE "-" lead of the charger to the NEGATIVE "-" battery terminal.
Turn ON the battery charger. Overcharging of Batteries
