Open-circuit and short-circuit wiring harness judgment system for multi-core wiring harness

The utility model discloses an open-circuit and short-circuit wiring harness determination system for a multi-core wiring harness, and the system comprises an analog input module which comprises a plurality of aviation plugs used for connecting one end of a wiring harness to be detected, and outputs detection currents to the wiring harnesses to be detected one by one; the analog quantity output module comprises a plurality of aviation plugs used for being connected with the other end of the wire harness to be detected, and transmits detection current to the digital quantity input module; the digital quantity input module converts the detection current into a digital signal; the digital quantity output module outputs the digital signal to the main control chip; and according to the digital signal, the main control chip displays that the to-be-detected wire harness is in an open circuit state when the digital signal output of the current to-be-detected wire harness is not received, and displays that the to-be-d
