1998 Ford Explorer Repair Question
Ford Explorer Battery Problem
Follow the smaller positive battery wire to the under-hood fuse box and be sure it's tight there. Also follow the smaller negative wire to the body and be sure it's tight. If those look fine, use a test light or voltmeter to follow the battery wires to see where you lose voltage. Also look for a large fuse bolted in on the fuse box and be sure those nuts are tight. Check the large copper nut on the starter relay. Those like to work loose over time.
