Power Distribution Center Step 2 - Identify the accessory fuse location by consulting identification information found in the fuse panel lid, owners manual or repair manual. Most electrical components are supplied with voltage and are protected though the pdc. The control relay and micro relay are used as a high amperage switch for devices that require high amounts of amperage for an extended amount of time. The fuse or fusible link supply voltage to sub electrical systems.
