A Comprehensive Guide To Understanding The Thermo King Tripac APU Wiring Diagram

As a truck driver or otherwise related to trucking, having an understanding of the wiring diagrams associated with equipment is essential. This article will provide a thorough overview of the wiring diagrams associated with the Thermo King Tripac APU, detailing each component and how they interact. If you want to understand the wiring in your rig or make repairs, a basic understanding of electrical wiring diagrams is necessary.

Thermo King Tripac APUs (auxiliary power units) are designed to reduce engine idling and save fuel costs when the vehicle is at a rest. This is done by providing auxiliary power to the vehicles cabin and key systems such as the HVAC and the 12-volt electrical circuits. The wiring diagrams associated with this equipment is often complex and intimidating if someone is not familiar with how they work. However, with a solid understanding of the wiring diagrams and components, it can be fairly straightforward to identify and rectify any problems that arise.

Overview Of Thermo King Tripac APU Wiring Components

In order for the Thermo King Tripac APU to function as intended, several wiring components are needed. Since the unit is used as both an electrical generator and charger, there are two primary locations where the wires need to be hooked up--one to the vehicle's fuse box and the other to the battery. In addition to these two points, a wiring diagram must be followed to ensure the proper connections are made between the various components.

The Thermo King Tripac APU requires wires from the dashboard which will provide power to the circuit board and different components within the unit. These include the control module, the starter motor, and the reactivation diode. This section will detail each component of the wiring diagram associated with this unit and how it interacts with the others to achieve the desired results.

The Control Module

The control module is responsible for controlling the electric current flow from the engine of the truck to the APU unit. This module serves as a bridge between the two and provides the signals needed in order to switch on the device or monitor its performance. The control module also communicates with the other devices within the APU, such as the starter motor, to ensure everything is running correctly. The wiring diagram outlines how this component is connected.

The Starter Motor

The starter motor is responsible for spinning the APU unit to get it started. Once started, the starter motor will shut off and allow the alternator, connected to the APU, to take over the task of powering the unit. The wiring diagram outlines which wires connect the starter motor to the other components and how the electric current will be routed through them.

The Reactivation Diode

The reactivation diode is responsible for protecting the system from overloads, allowing the electrical current to pass through without disrupting the operation. The wiring diagram outlines where the reactivation diode should be located, how it should be connected, and how it interacts with the rest of the system.

Conclusion

While understanding the wiring diagrams associated with the Thermo King Tripac APU may be a daunting prospect, knowing the different components and how they connect can help you handle any potential issues quickly and efficiently. Whether you’re making repairs or just want a better understanding of the wiring in your rig, having a grasp of the wiring diagram and its components can be extremely beneficial.
