Wiring harness checking method

A checking method for determining acceptance or rejection of a wiring harness having a plurality of first sub-harnesses and a plurality of second sub-harnesses,

• the first sub-harness having a plurality of first electrical cables, a plurality of first press-fit terminals, and a first isolator, the first press-fit terminal being joined to each end of the first electrical cable, the first isolator holding the first press-fit terminals positioned at one end of the first sub-harness,
• the second sub-harness having a plurality of second electrical cables, a plurality of second press-fit terminals, a plurality of crimp terminals, a connector housing for accommodating the crimp terminals, and a second isolator supporting the second press-fit terminals, the second press-fit terminal being connected to one end of the second electrical cable, the crimp terminal being connected to the other end of the second electrical cable,
• wherein, when any of the first and second isolators are layered, the press-fit terminals held by different ones of the isolators can be connected to one another,
• the method comprising the steps of:
• assembling the first sub-harness;
• assembling the second sub-harness;
• conducting a first continuity check of the first sub-harness for determining acceptance or rejection thereof after assembling the completed first sub-harness,
• conducting a second continuity check of the second sub-harness for determining acceptance or rejection thereof after assembling of the second sub-harness,
• layering the isolators of the first and second sub-harnesses to complete the wiring harness, and
• conducting a third continuity check of the layered sub-harnesses for determining acceptance or rejection of the wiring harness after layering the isolators of the first and second sub-harnesses to complete the wiring harness.
