🔍 Key Concepts

• Routine versus non-routine (specialized) maintenance on electrical machinery • Cooling and ventilation requirements for alternators • Which components normally require specialist testing or manufacturer involvement

💭 Think About

• Which choice sounds like a simple, regularly scheduled task that ship’s crew would safely perform without special test equipment? • Which options involve actions that, if done incorrectly or too often, could damage the alternator or are usually done only under specific fault conditions? • Think about what part of an alternator must stay clean to keep it cool and prevent overheating or insulation breakdown.

✅ Before You Answer

• Identify which task is clearly preventive maintenance rather than troubleshooting or repair. • Ask whether the task would reasonably be done on a schedule for all alternators, not just under fault conditions. • Consider the safety and practicality of each option for routine shipboard maintenance.
