When servicing the battery cables, make sure both the
Ignition Switch and all electrical accessories are off. Loosen the negative cable terminal fastener from the negative battery terminal by using a terminal puller if you have one. Open up the positive cable terminal clamp cover, disconnect the positive cable from the battery and use a puller if labor on this step becomes necessary. Detach the screw that plugs the battery negative cable into the inner
Fender, then pull out and lift up the lid for both the Power Distribution Center and the Integrated Power Module. Remove the two nuts that attach the battery positive cable eyelet terminal to the B(+) terminals in the PDC and the other nut doing the same in the IPM, then pull off the terminals from both B(+) studs. Gently pull out the connection for the battery wire harness three pin connector from the
Battery Tray. On 3.7L and 4.7L engines, take out the nut securing the eyelet terminal of the generator output cable to the generator terminal stud and separate the battery wire harness connector from the generator field terminal connector receptacle. Depress the retaining clip on the battery wire harness and carefully slide it off the top of the valve cover stud. For these engines, remove the nut that attaches the generator output cable eyelet terminal to the generator output terminal stud, separate the generator field terminal connector wires from the connector receptacle on the battery wire harness and remove the battery wire harness retaining clips off the valve cover studs. After raising the vehicle on a hoist, for the 6.1L engine, pull off the retaining clips under the engine on the wire harness that holds the battery. Lift out the bolt connecting the battery negative cable to the engine's chassis, remove the nut joining the battery positive cable to the starter solenoid stud and pull off the battery positive cable from the B(+) terminal stud. Come to the final step by disconnecting the battery wire harness connector from the starter solenoid, removing the clips holding the harness on the engine and wiping the battery wire harness from inside the engine compartment.
