as temperature extremes, moisture and automotive fluids. Electrical wiring and equipment <br />shall be installed utilizing the following guidelines: <br />1. All wire ends not placed into connectors shall be sealed with a heat shrink end cap. <br />Wires without a terminating connector or sealed end cap shall not be allowed. <br />2. All holes made in the roof shall be caulkers with silicon (no exception). Large fender <br />washers, liberally caulked, shall be used when fastening equipment to the underside <br />of the cab roof. <br />3. Any electrical component that is installed in an exposed area shall be mounted in a <br />manner that shall not allow moisture to accumulate in it. Exposed area shall be <br />defined as any location outside of the cab or body. <br />4. For low cost of ownership, electrical components designed to be removed for <br />maintenance shall be quickly accessible. For ease of use, a coil of wire shall be <br />provided behind the appliance to allow them to be pulled away from the mounting <br />area for inspection and service work. <br />5. Corrosion preventative compound shall be applied to non -waterproof electrical <br />connectors located outside of the cab or body. All non -waterproof connections shall <br />require this compound in the plug to prevent corrosion and for easy separation of the <br />plug. <br />6. Any lights containing non -waterproof sockets in a weather -exposed area shall have <br />corrosion preventative compound added to the socket terminal area. <br />7. All electrical terminals in exposed areas shall have DOW 1890 protective Coating <br />applied completely over the metal portion of the terminal. <br />8. Rubber coated metal clamps shall be used to support wire harnessing and battery <br />cables routed along the chassis frame rails. <br />9. Heat shields shall be used to protect harnessing in areas where high temperatures <br />exist. Harnessing passing near the engine exhaust shall be protected by a heat shield. <br />1 O.Cab and crew cab harnessing shall not be routed through enclosed metal tubing. <br />Dedicated wire routing channels shall be used to protect harnessing therefore <br />improving the overall integrity of the vehicle electrical system. The design of the cab <br />shall allow for easy routing of additional wiring and easy access to existing wiring. <br />11.All braided wire harnesses shall have a permanent label attached for easy <br />identification of the harness part number and fabrication date. <br />12.All standard wiring entering or exiting the cab shall be routed through sealed <br />bulkhead connectors to protect against water intrusion into the cab. <br />3ATTERY CABLE INSTALLATION <br />All 12-volt battery cables and battery cable harnessing installedby the apparatus <br />manufacturer shall conform to the following requirements: <br />SAE J 1127 - Battery Cable <br />SAE J561 - Electrical terminals, eyelets and spade type <br />SAE J562 -Nonmetallic loom <br />SAE J836A - Automotive metallurgical joining <br />SAE J1292 - Automotive truck, truck -tractor, trailer and motor coach wiring <br />NFPA 1901 - Standard for automotive fire apparatus <br />Battery cables and battery cable harnessing shall be installed utilizing the following <br />guidelines: <br />67 <br />
