“All vehicles are equipped with an Ignition-Off Draw (IOD) fuse which is used when the vehicles are originally shipped from the factory. This fuse #F1, which is located in the Power Distribution Center, helps to prevent battery discharge during storage. For specific location refer to Group 8W – Wiring Diagrams. The IOD fuse includes the radio memory circuitry and should be checked if the memory (time or radio station programming) is inoperative. The radio is connected to fuse #8 in order to retain the radio’s memory when the ignition switch is turned to OFF.” (page 1).
