The wire harness is a multi-strand copper cord with a plastic sheath. at high temperature, plastic inevitably releases chemicals such as plasticizers. these chemicals react with the copper core wire, causing the strength of plastic to drop and the resistance of the copper core wire to rise. as a result, it is easy to cause the wire harness to age. How to delay the aging of wiring harness? The following small series will introduce you.
The digital multimeter can measure basic parameters such as voltage, current, resistance, capacitance and transistor, etc. it can also be used flexibly to further expand its function and achieve the purpose of multi-purpose for one meter. Use digital multimeter cable break point method to judge.
