^ KEEP BODY FROM UNDER THE AUXILIARY OR SECONDARY BATTERY WHEN DISCONNECTING OR RECONNECTING THE AUXILIARY OR SECONDARY BATTERY SAFETY STRAPS SINCE THE BATTERY WEIGHS 50 POUNDS AND BODILY INJURY CAN RESULT.
1. Disable the vehicle electrical supply; refer to Dual Battery Disconnect in General Procedures.
CAUTION: Failure to accurately follow the battery disconnect procedures outlined will result in vehicle or component damage.
NOTE:
^ The preferred method of service requires the use of a floor hoist to lift the vehicle overhead, and a transmission jack to support and lower the auxiliary or secondary battery case.
^ The auxiliary or secondary battery can be charged while the auxiliary or secondary battery safety straps are connected to the vehicle. Follow the procedures up to and including disconnection of the auxiliary or secondary battery cables.
2. Remove the two auxiliary or secondary battery cable harness screws retaining the harness to the frame.
3. Support the bottom of the auxiliary or secondary battery and case with a transmission jack.
4. Remove the auxiliary or secondary battery case from the frame.
1 Remove the upper RH auxiliary or secondary case to frame bolt.
2 Loosen, but do not remove, the three remaining battery case-to-frame bolts.
3 Raise the battery case slightly and move away from the frame to dislodge the battery case from the three remaining bolts.
4 Remove the remaining three battery case-to-frame bolts.
NOTE: Shown with body removed for clarity.
5. Lower the auxiliary or secondary battery and case until tension is almost present in the auxiliary or secondary battery case safety straps.
6. Remove the two auxiliary or secondary battery case cover bolts and disengage the battery case cover.
7. Remove the auxiliary or secondary battery cables.
8. Remove the two auxiliary or secondary battery case safety strap to frame bolts.
9. Disengage the auxiliary or secondary battery case safety straps and roll the auxiliary or secondary battery and case away from the vehicle.
