Battery Handling Precautions
Before servicing the vehicle’s electrical system, always disconnect the service disconnect first, then disconnect any electrical accessory connections, then disconnect the negative cable from the 12-volt battery, then disconnect the negative terminal from the main battery pack. See Service Disconnect section in the Features and Control chapter for more information. This will disable the vehicle by disconnecting the battery pack from the motor. It does not disable the battery pack. HIGH VOLTAGE will be present at the battery terminals and contactor.
HIGH BATTERY VOLTAGE IS ALWAYS PRESENT. DO NOT TOUCH THE BATTERY TERMINALS.

Always make sure that all 12-volt electrical accessories are grounded directly to the negative (-) post on the terminal board. Never use the chassis or body as a ground connection. See 12–Volt Terminal Board Connections section in the Features and Controls chapter.
-
Make sure vent caps are installed properly and securely during vehicle operation and battery charging.
-
Never connect a 12–volt accessory directly to the batteries. Always connect any powered accessory to the 12–volt terminal board. See 12–Volt Terminal Board Connections section in the Features and Controls chapter.
