The answer to 'difference between troubleshooting' is that troubleshooting is the process of identifying and resolving issues or problems with electrical systems, while testing is the systematic evaluation of electrical components and circuits to verify their proper function. Troubleshooting focuses on diagnosing and fixing problems, while testing is more about verifying that everything is working as intended.
Troubleshooting typically involves using a methodical approach to isolate the source of the problem, such as checking for power, inspecting connections, testing individual components, and analyzing error codes. Testing, on the other hand, is often done as a preventative measure or to ensure that new installations or repairs are functioning correctly.
