Check the primary under-hood control panel for all major power distribution points. The main relay for the ignition system is located in the top-left section, rated at 30 amps, and controls both engine management modules and fuel pump circuits.
Passenger compartment panels house lower amperage circuits such as lighting, infotainment, and climate control. Each slot is labeled with its assigned rating, typically between 5 and 20 amps, allowing for rapid identification during troubleshooting or component replacement.
Relays for high-draw components like the radiator fan and auxiliary power outlets are grouped near the main fuse carrier. Use the labeled reference card on the panel cover to match each circuit to its function and prevent overloading sensitive electronics during repairs.
Connector pins and terminals in both panels are color-coded for voltage and grounding paths. Red indicates constant power, yellow shows switched power, and black marks ground connections, which helps avoid cross-wiring or shorts when inspecting circuits.
Maintenance tip: Always disconnect the negative battery terminal before servicing any panel. Confirm amperage limits with the panel label and replace any protective device with one of the same rating to maintain system integrity and prevent electrical faults.
Electrical Panel Guide and Circuit Assignments for 2022 Charger
Locate the main under-hood power distribution panel to access high-amperage circuits such as the starter, radiator fan, and primary ignition relays. Each slot is labeled with its assigned rating, typically ranging from 20 to 40 amps, allowing quick verification of circuit protection before replacing components or performing diagnostics.
Interior panels control lower amperage functions including lighting, audio, and climate modules. Circuit positions are marked on the panel cover with both function and rating, and color-coded terminals indicate constant, switched, or ground connections, which simplifies tracing wires and prevents accidental shorts during repairs.
Engine Compartment Electrical Layout and Amperage Ratings
Check the power distribution panel under the hood for circuits that supply the starter motor, cooling fans, and fuel pump relays. Each connection is marked with an amperage value, generally between 20 and 60 amps, which ensures the correct rating is applied before replacing any components or performing voltage tests.
High-current terminals and relays are grouped for accessibility. Common slots include:
- Main ignition relay – 40 amps
- Radiator fan – 50 amps
- Fuel injection – 30 amps
- ABS control – 25 amps
Follow the color-coded labels for ground, switched, and constant lines to prevent accidental shorts during inspection or maintenance.
