Ravon R3 (1st generation): Electrical System Reference

The Ravon R3 is built on the Chevrolet Aveo T300 platform. It has a 12 V electrical system with negative polarity and the body as ground. The system includes two main fuse and relay boxes, an OBD-II diagnostic connector, and several distributed ground points. Below you will find the location of the components, the purpose of the main circuits, and wire colors for common jobs.

Part

  • 🔩 Fuses, 5-40 A (as needed)

Step by step

7 steps
  1. Interior fuse box — It is located on the left under the instrument panel, behind a protective cover. It holds the fuses for the interior systems: F13 (cigarette lighter, 15 A), F1 (airbag module), F7 (brake lights), F10 (instrument cluster), F14 (interior lighting), F20 (heated mirrors), F21 (rear window defogger). The layout diagram is printed on the back of the cover.
  2. Engine compartment fuse and relay box — It is mounted behind the coolant reservoir. It holds the high-current fuses (5-40 A) and the relays for the engine, cooling and lighting systems: F1 (battery), F7-F8 (headlights), F16 (fuel pump), F17 (engine control module), F23 (ABS); relays R1 (fuel pump), R5 (high beam), R7-R8 (two-speed cooling fan), R10 (main relay). The box cover is marked with the component designations.
  3. High-current fuses at the battery terminal — There are four high-current fuses: 80 A (electric power steering), 400 A (starter), 80 A (interior fuse box), 150 A (engine compartment fuse box). They are located directly on the positive battery terminal under a protective cover.
  4. OBD-II diagnostic connector — It has 16 pins and is located on the left under the instrument panel, on the driver's side. It follows the OBD-II standard and works with universal scan tools. Power and communication pins: 4 and 5 (ground), 16 (constant +12 V from the battery), 6 and 14 (CAN bus high/low).
  5. Color coding of the main circuits — Ignition: pink wire (ACC), orange wire (ignition 2). Constant +12 V power: red wire. Starter: violet/black wire (in the upper connector of the fuse box on the left). Door switches: gray/black wire (under the trim on the left, in the driver's footwell). Trunk switch: gray wire. Injectors (engine control): any left-hand wire at the injector connector.
  6. Ground points — The main grounding points are: the negative battery terminal, the stud on the engine block (powertrain ground), points on the firewall (body ground for the interior electronics), and the bolts under the front panel (instrument ground). When connecting accessories, use the nearest factory ground point or a body mounting bolt at least 6 mm in diameter, and clean the contact surface down to bare metal.
  7. Platform notes — The Ravon R3 shares its platform with the Chevrolet Aveo T300, so the connectors, harness layouts and box locations are identical. When looking for electrical parts (switches, sensors, wiring harnesses), search for both makes. The Aveo T300 wiring diagrams are fully applicable for diagnosing the R3.

Common mistakes and warnings

  • Disconnect the negative battery terminal before working on the electrical system. Never replace a fuse with one of a higher rating than specified, because the overloaded circuit can overheat and start a fire in the wiring. Always verify the fuse ratings against the markings on the box cover in your own vehicle, because trim levels may differ by model year.
