Recreational Vehicle (RV) Technician Practice Test

What should you consult to find the proper wire location after discovering an unconnected wire?

1. Owner's manual

2. Printed circuit schematic

3. Electrical wiring diagram

4. Manufacturer guidelines

The correct answer is: Printed circuit schematic

To determine the proper wire location after finding an unconnected wire, consulting the printed circuit schematic is the most effective approach. A printed circuit schematic provides a detailed representation of the electronic circuitry, including all connections and paths for current flow. It indicates how components are related and guides technicians on the intended connections of each wire. While the owner's manual provides useful information about the RV's general operation and maintenance, it may not detail specific wiring configurations. Manufacturer guidelines can offer insights, but they are usually broader and may not focus specifically on circuit layouts. An electrical wiring diagram, while helpful, generally represents the physical layout rather than the logical connections of the circuit. Thus, the printed circuit schematic is the best option for accurately determining where the unconnected wire should be connected.
