What is a Cole Hersee Wiper Switch Wiring Diagram and How is it Used?
A Cole Hersee Wiper Switch Wiring Diagram is a visual representation that illustrates the connections between the wiper switch, the wiper motor, and other electrical components within a vehicle's wiper system. Cole Hersee is a well-respected manufacturer of electrical components for heavy-duty vehicles, so their diagrams are often found in applications ranging from trucks and buses to agricultural equipment and RVs. These diagrams simplify complex wiring by using standardized symbols to represent different electrical parts and lines, making it easier to trace the flow of electricity.
The primary purpose of a Cole Hersee Wiper Switch Wiring Diagram is to guide the installation, troubleshooting, and repair of wiper systems. It details which wire connects to which terminal on the switch, and how those terminals correspond to the power source, the wiper motor itself, and often accessory functions like washer pumps or intermittent wiper modules. For example, a typical diagram might show:
- The battery or ignition power input.
- The connection to the low-speed winding of the wiper motor.
- The connection to the high-speed winding of the wiper motor.
- The connection for the park function, which returns the wipers to their resting position.
- Any additional terminals for optional features.
The importance of correctly interpreting and following the Cole Hersee Wiper Switch Wiring Diagram cannot be overstated, as incorrect wiring can lead to a non-functional wiper system, blown fuses, or even damage to the wiper motor or switch.
To effectively use a Cole Hersee Wiper Switch Wiring Diagram, you'll typically need to identify your specific wiper switch model. Manufacturers often have different switch configurations for various functions (e.g., two-speed, three-speed, with washer). Once you have the correct diagram for your switch, you can use it in several ways:
- Installation: When replacing a faulty switch or installing a new wiper system, the diagram serves as your installation guide, ensuring all wires are connected to their designated terminals.
- Troubleshooting: If your wipers aren't working, the diagram helps you trace the electrical path to pinpoint where a break in the circuit, a loose connection, or a faulty component might be causing the problem.
- Maintenance: Regular checks and cleaning of connections can be guided by the diagram, ensuring the longevity of your wiper system.
Here's a simplified look at what you might find on a typical diagram, though specific terminals and their functions can vary:
| Terminal Label | Typical Function |
|---|---|
| BAT (or 30) | Battery/Constant Power Input |
| LOW (or 1) | Low Speed Wiper Motor Connection |
| HIGH (or 2) | High Speed Wiper Motor Connection |
| PARK (or 3) | Wiper Motor Park Function Connection |
| ACC (or Washer) | Accessory Power/Washer Pump Connection |
