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
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 | |
|---|---|---|---|---|---|
| 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 |
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.
