Onan generators provide power to various appliances and equipment in vehicles, boats, and homes. However, like any other electrical equipment, they may require maintenance or troubleshooting at some point. One aspect that you should understand is the wiring diagram for Onan generator coil wiring. This article provides a comprehensive guide on this topic.
Understanding Onan Generator Coil Wiring
Before diving into the wiring diagram, it’s essential to understand how the Onan generator coil wiring works. Essentially, the generator coil or Rotor generates a magnetic field that moves past the stationary Stator. This generates an electrical current in the Stator, which powers the appliances or equipment.
Notably, there are two types of Onan generators – those with a mechanical voltage regulator and those with an electronic voltage regulator. The wiring diagram may vary depending on your generator model. For simplicity purposes, we’ll focus on the mechanical voltage regulator Onan generators.
Onan Generator Coil Wiring Diagram
Now let’s delve into the wiring diagram for Onan generator coil wiring. This diagram shows the various components and wires in the Onan generator system.
| Color | Wire | Function |
|---|---|---|
| Green | F1 | Field Excitation |
| Red | B1 | Battery Positive |
| Black | C1 | Ground / Negative |
| Yellow | AC1 | AC Output |
| Blue | AC2 | AC Output |
| White | AC3 | AC Output |
| Purple | Field | Field Excitation |
| Brown | Ground | Ground / Negative |
From the diagram, the green wire (F1) is connected to the Rotor (Field Excitation). The red wire (B1) connects to the battery positive, while the black wire (C1) connects to the ground or negative side.
The yellow, blue, and white wires (AC1, AC2, AC3) are the AC output wires that provide power to the appliances or equipment. Notably, the AC output wires are interchangeable, meaning you can connect either of them to the appliances or equipment.
The purple wire connects the field excitation to the voltage regulator, while the brown wire connects the ground terminals.
