When something electrical stops working on your boat, it can feel like a mystery.
Is it the battery? A connection? A wiring issue? And where do you even begin?
In this workshop, Nigel Calder breaks troubleshooting down into clear, step-by-step processes that any boat owner can follow. Using simple tools—especially a multimeter—you’ll learn how to identify the most common electrical problems and trace them to their source.
No prior experience is required. This is about building confidence—understanding what you’re looking at, knowing what to test, and being able to take action instead of guessing.
Along the way, you’ll also learn how to prevent common issues like premature battery failure and avoid unnecessary service calls.
On today’s increasingly complex boats, electrical systems can be one of the biggest sources of frustration—or one of the most empowering areas of knowledge.
This workshop helps tip the balance. It complements the morning session on electrical installation issues, but can be taken independently.

This workshop is the second of two complementary electrical sessions on Friday. Each can be taken independently, but together they provide a deeper understanding of onboard electrical systems.
