How to quickly check the on-off of wire harness

The harness loop detection equipment used by harness manufacturers can detect the open circuit and wrong circuit of the harness, and we usually become the harness loop detection platform.

Manually point a homemade tool at the drawing, which we call a connector (you can change the system with the doorbell and remove the doorbell switch). One end is positive, and the other end is negative) As long as two or more points (welding wires) of the harness are connected at the specified sheath hole, it can be judged whether the harness is open or wrong. This method is often a manual test of new product trial production. )
