Honda NTV650 Revere - Wiring diagram
Here it is the wiring diagram drawn in color. It was derived by me from a black and white printed diagram from Honda. Inspecting the original drawing I spotted two erros: there were two missing joints. Both were in the main harness, one on the green wires and the other in the white/green wires.
Here it is the the PDF version: Honda NTV650 Revere wiring diagram (PDF).
Headlight wiring
Harness wires gauge
Inside the main wiring harness you will find at least three types of cables; they are stranded cables of different gauges, these are the specifications:
| Outer diameter | Number of strands | Strand diameter | Cross-section area | AWG equivalent | |
|---|---|---|---|---|---|
| Thin | 1.70 mm | 20 | 0.16 mm | 0.40 mm² | 21 AWG 20/34 |
| Medium | 1.85 mm | 30 | 0.16 mm | 0.60 mm² | 19 AWG 30/34 |
| Thick | 2.65 mm |
The outer diameter refers to the overall cable, including the insulator. The AWG gauge is calculated measuring the diameter of the single strand and calculating the overall cross-sectional area; then the nearest value is looked into the AWG gauge table.
Fuel pump connector polarity
After disassembling the carburetors you may want to force the fuel to fill them again. Using the start button and letting the entire engine rawwing for a long time may be an high load for the battery, so you may prefer to provide 12 V directly to the pump connector.
In this photo you see the polarity (red is positive and black is negative) of the connector from the wiring harness to the pump:
You will hear the noise from the working pump. Ance the carburetors are full, the pump will stop.
