There are few things more frustrating than electrical-system problems on your boat. Diagnosing these problems requires skilled technicians who have the right equipment.
The Six Sub-Systems: The electrical system on your vessel is a collection of six smaller sub-systems that need to work in harmony. These systems are: power source, protection, control, load, ground and wiring. The battery is considered the power source, protection is the fuse or circuit breaker, control is the switch, load is the component doing the work (lights, electronics, etc), and a good ground to complete the circuit. Wiring is what connects everything together. When any of these six components fail the system will not work.
