Electrical System All the electrical circuits have fuses to protect them from a short circuit or overload. If something electrical on your chassis stops working, the first thing you should check for is a blown fuse. 1. Turn OFF all lights and accessories and remove the ignition key to avoid damaging the electrical system.. 2. Determine from the chart on the fuse panel which fuse controls that component. 3. Remove that fuse and see if it is blown. 4. If it is blown, replace it with a fuse of the same rating. Adding Electrical Options WARNING! Do not add a fuse with a rating higher than 30 amps. Doing so may damage the electrical system and cause a fire. CAUTION: Follow all manufacturers’ circuit protection recommendations for the components and wires being added. Spare circuits are located throughout the wiring for the dash. For proper electrical system performance, refer to a wiring diagram for your chassis before adding electrical options. Truck-Body Connection Preventive Maintenance Your vehicle includes a junction box mounted to the frame for wiring the vehicle body to the main chassis harness. Refer to the Body Builder's Manual for further information on using the Truck and Body Connection. Batteries WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. Battery Access The vehicle is originally equipped with two batteries. Replacement batteries must meet the following specifications: maintenance-free, group 31 size, threaded stud, 12V/ 650 cold cranking ampere (CCA), and 160 minutes of reserve capacity. The battery compartment has space to install an optional third battery. – 214 – Y53-6008A Medium Duty (R05/09)
Preventive Maintenance The battery compartment is located on the left side of the vehicle, under the cab access steps. The cover is held in place by two latches one on each side. WARNING!
