What is a common electrical troubleshooting step for intermittent problems?

The process of troubleshooting intermittent electrical problems often starts with a thorough visual inspection of connectors and wiring. This approach is effective because intermittent issues frequently stem from poor connections, frayed wires, or corrosion that disrupts the electrical flow. By checking for obvious signs of damage or wear, a technician can identify potential fault points that may not be easily detectable through electrical tests alone.

Visual inspection allows for the immediate identification of problems that can lead to intermittent failures, such as loose connectors, broken wires, or oxidation on terminals. Addressing these physical issues can often resolve the problem without the need for more invasive testing or replacement of components. This method supports systematic troubleshooting and helps isolate the issue effectively.
