Learning Outcomes

After completing this course, the student will be able to:

1. Demonstrate an understanding of marine storage batteries by correctly transporting, determining battery condition, and applying industry standards.
2. Demonstrate safe work best practice when working on alternating current circuits by being aware of shock hazards, proper multi-meter use, and not touching energized wires or terminals.
3. Use a digital volt/ohm/amp meter to test battery voltage, shore power cords, voltage drop, continuity of a wire run, operation of a switch, fuse, bulb or appliance in a AC or DC electrical system.
4. Demonstrate understanding of engine operation gauge systems by correctly installing and troubleshooting common gauge circuits.
5. Install and wire typical vessel DC electrical system components such as batteries, pumps, lights, switches and navigational gear to American Boat and Yacht Council and National Fire Protection Association guidelines and recommended practices.
6. Troubleshoot & repair DC electrical systems including battery charging, engine alternators, pumps, lights, switches and navigational gear.
7. PROGRAM OUTCOME: Demonstrate Mechanic & Electrical Skills.
