What effect does corrosion have on electrical connections?

Corrosion on electrical connections typically leads to an increase in resistance within those connections, which directly contributes to poor electrical conductivity. When corrosion forms, it creates an insulating layer that inhibits the flow of electricity. This increased resistance can cause several issues, such as voltage drops, excessive heat generation, and reduced performance of electrical components. Such problems can lead to symptoms like flickering lights, weakened signals, or even complete failure of the electrical system in automotive applications. Therefore, understanding that corrosion negatively affects electrical connectivity is crucial for maintaining effective automotive electrical systems.
