Don’t get short-circuited; learn how boat electrical systems work, how to diagnose problems, and how to do simple repairs and upgrades.

Boat electrical systems are increasingly under load with power demands for electronic navigation, radar, powered windlasses and winches, interior and exterior lighting, personal electronic devices, and more. Most boats have both DC and AC power. Learn about voltage drops, current demands, wiring, and so on. This course covers the topics you need and want to know.

What's included?

• Boat electrical wiring practices
• Direct current (DC) power
• Alternating current (AC) power
• Galvanic and stray current corrosion
• Lightning protection
• How to use a multi-meter
• How to solder and crimp
