Wiring diagrams are an essential part of any vehicle’s electrical system. They enable mechanics and technicians to diagnose and repair faults in the wiring and electrical components. In this article, we will discuss the wiring diagram for the 2017 Dodge Ram 1500. We will also provide some frequently asked questions and a table of the electrical components.
Introduction
The 2017 Dodge Ram 1500 is a full-size pickup truck that comes in various cab and bed configurations. It is equipped with a range of engines, including a 3.6L V6, 5.7L V8, and 3.0L V6 diesel engine. The electrical system of the 2017 Dodge Ram 1500 comprises several components, including the battery, alternator, starter, ignition switch, powertrain control module (PCM), and various sensors.
Battery
The battery is the heart of the electrical system. It provides the initial power to start the engine and also powers the accessories when the engine is off. The 2017 Dodge Ram 1500 is equipped with a 12-volt battery located in the engine compartment. The battery is connected to the starter motor, alternator, and various electrical components through the battery cables.
The battery cables are color-coded for easy identification. The positive cable is red, and the negative cable is black. The positive cable is connected to the starter motor and the alternator. The negative cable is connected to the engine block or chassis ground.
Alternator
The alternator is responsible for recharging the battery and powering the electrical components when the engine is running. The 2017 Dodge Ram 1500 is equipped with a 160-amp alternator. The alternator is connected to the battery through the battery cables and a fusible link located in the power distribution center (PDC).
The alternator is also connected to the PCM through a three-wire connector. The PCM controls the output of the alternator by sending signals to the voltage regulator.
Starter
The starter is responsible for cranking the engine and starting it. The 2017 Dodge Ram 1500 is equipped with a starter motor located on the side of the engine block. The starter motor is connected to the battery through the positive cable and to the ignition switch through a starter relay.
When the ignition switch is turned to the start position, the starter relay is energized, and the starter motor cranks the engine. The PCM also plays a role in starting the engine by controlling the fuel injection and ignition timing.
