Locate the main power control module under the hood near the battery to inspect circuits for ignition, lighting, and auxiliary components. Each terminal is labeled with amperage to simplify identification and testing.
Use a digital multimeter to verify voltage and continuity before replacing any relay or connector. Key ratings include 10A for interior lighting, 20A for cooling fans, and 30A for starter and ignition circuits, ensuring safe maintenance.
Keep a printed slot chart in the glove compartment to match each connection to its designated terminal. This prevents misplacement and reduces the risk of damaging sensitive electronics during repairs.
Disconnect the battery before removing or installing components to avoid sparks and protect modules. Following proper sequence maintains reliable operation of all onboard electrical systems.
2014 Infiniti Q60 Electrical Panel Overview
Access the primary power module under the hood near the battery to check circuits controlling ignition, headlights, and auxiliary systems. Each slot is labeled with amperage ratings, allowing accurate identification for testing or replacement without risk of miswiring.
Inspect high-current and low-current terminals separately using a digital multimeter to verify voltage and continuity. Common ratings include 10A for interior lighting, 20A for cooling fans, and 30A for starter and ignition circuits. Maintaining a reference chart of each slot ensures correct placement of relays and connectors during maintenance.
Accessing the Main Power Module in the Engine Compartment
Locate the primary electrical module near the battery on the driver’s side to reach circuits for ignition, lighting, and auxiliary systems. The cover is secured with clips that can be released manually without tools.
Disconnect the negative battery terminal before handling any connections to prevent sparks and protect sensitive electronic components. This step is mandatory before inspecting or replacing relays and connectors.
The module contains both high-current and low-current terminals clearly labeled with amperage ratings. Common slots include:
- 10A for dashboard and interior lighting
- 20A for cooling fans and power accessories
- 30A for starter and ignition circuits
Use a digital multimeter to check each slot for proper voltage and continuity. Look for signs of corrosion, burnt contacts, or loose connections that can cause intermittent failures or prevent components from operating correctly.
Maintain a printed reference chart showing each slot and its corresponding circuit. This allows quick verification during troubleshooting and ensures relays and connectors are reinstalled correctly without errors.
After inspection or component replacement, secure the module cover and reconnect the battery. Test all circuits controlled by the module to confirm proper operation and prevent electrical issues before driving the vehicle.
