Wiring Schematic and Schedule

From-To connector references are specified to form a point-to-point wiring list. Wiring schematics and schedules can then be generated automatically from the information included in the wire list and harness assembly drawing.

These schematic diagrams and schedules show the pin to pin wiring for all the connectors and wires in a harness design. The wiring details can be entered via HarnWare then the output can be drawn in Visio, the user has a choice to show the details as a Wiring Schematic or a Wiring Schedule (tabulated format).

“Wires, connectors and switches are designed to conduct current with a minimum loss of voltage. A voltage drop of more than one volt indicates a problem. To test a voltage drop, connect the voltmeter leads to connectors at either end of circuit’s suspected problem area. The positive lead should be connected to the connector closest to the power source. The voltmeter will show the voltage drop between these two points.”
