Note the diagram. See the top cable from positive side of battery, that cable goes to under hood fuse box. When problem is ongoing,Use a test light and check voltage on both ends of that cable, if voltage on one end but not the other, replace cable. Make sure connections are good and clean, also cable ends. voltage and grounds are important.
