Check Batteries: “Always make sure batteries are fully charged and load tested. Defective and/or inadequate batteries are one of the most common causes of problems in marine electrical systems!”
Check Connections: “Be sure all connections and terminals are tight and clean. Also, battery cable terminals need to be tight and should have a gap between the top of the terminal and the side of the clamp!”
Check Wiring: “Remember to always tag wiring when removing any electrical unit. Also, feel the lines for soft spots. Soft spots usually indicate the wire is corroded and needs to be replaced!”
Check for High Resistance: “Be sure to check for voltage drops. Low voltage will ruin your electrical components and shorten the life of a battery!”
