Learning Outcomes

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

1. Determine battery condition by voltage testing, load testing, and cell density testing, amp/hr testing.
2. Plan and install a second battery with selector switch for a single battery boat.
3. Safely lift, carry, and transport heavy batteries.
4. Work safely with 120 volt AC by being aware of shock hazards and not touching energized wires or terminals.
5. Understand chemical hazards of acid burns with electrolyte in batteries.
6. Use a digital volt/ohm/amp meter to test battery voltage, voltage drop in a DC system, continuity of a wire run, operation of a switch, fuse, bulb or appliance.
7. Use a digital volt/ohm/amp meter to test AC circuits including shore power cords, supplied voltage, voltage drop, continuity of a wire run, operation of a switch, fuse, bulb or appliance.
8. Demonstrate understanding of engine operation gauge systems by correctly troubleshooting common gauge circuits.
9. Measure condition of alternator/voltage regulator DC charging system operation using a volt meter.
10. 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.
11. Install and wire typical vessel AC system components such as shore power inlets, galvanic isolators, distribution panels, duplex, receptacles, lights and battery chargers to ABYC and NFPA guidelines and recommended practices.
12. Troubleshoot and repair common engine monitoring gauge problems.
13. Troubleshoot alternator operation using the 3-step method and engine starting system wiring and components.
