- Turn ignition on. Using a voltmeter connected to ground, backprobe control switch/timer relay module connector terminals No. 1 and 2. See Fig 1 . If battery voltage is present, go to next step. If battery voltage is not present, inspect fuse No. 7 (10-amp) in fuse block and maxi-fuse No. 10 (40-amp) in Power Distribution Center (PDC). PDC is located in engine compartment, next to battery. If either fuse is blown, inspect and repair suspect short circuit. See WIRING DIAGRAMS . Replace fuse. If fuses are okay, go to next step.
