When diagnosing electrical issues, what does high resistance in a connection typically indicate?

High resistance in a connection typically indicates a faulty connection. In automotive electrical systems, a good connection should have low resistance, allowing for efficient flow of current. When resistance is high, it can disrupt the normal flow of electricity, leading to various issues such as dimming lights, poor performance of electrical components, or even failure to operate altogether.

Faulty connections can arise from several factors, including corrosion, loose connectors, or damaged wiring. These conditions increase resistance and can significantly affect the performance and reliability of the electrical system in a vehicle. Therefore, recognizing high resistance as a symptom of a faulty connection is crucial for effective diagnosis and troubleshooting in automotive electrical systems.
