Access the main power module under the hood to check circuits controlling the starter, alternator, and cooling fans. Each slot is labeled with amperage ratings to ensure correct replacements and prevent overloads.
Inspect the interior control panel behind the dashboard for circuits operating interior lights, audio systems, and climate controls. Use numbered positions and color codes to identify each connector before attempting removal or testing.
Replace any corroded or discolored terminals immediately to prevent intermittent faults. Keep spare relays and connectors rated for the system for quick replacement.
Test each circuit with a multimeter to confirm continuity and locate malfunctions. Document slot locations and functions to simplify future maintenance and avoid misconnection of components.
Maintain a reference sheet of all panels and connectors. Regular inspections of terminals and relays help preserve consistent electrical performance and reduce unexpected failures during operation.
Electrical Panel Layout with Circuit Locations and Functions
Locate the main power module in the engine compartment to access circuits controlling the starter, alternator, and cooling fans. Each terminal is clearly labeled with amperage ratings for safe replacement and verification.
Check the interior control panel under the dashboard for circuits operating lighting, audio, and climate systems. Numbered slots and color-coded connectors simplify identification before testing or replacement.
Inspect all terminals and relays for corrosion, discoloration, or heat damage. Replace any compromised components immediately to maintain stable electrical performance.

Engine Compartment Power Module Layout and Circuit Assignments
Open the hood and locate the power distribution unit next to the battery to identify high-load circuits tied to starting and cooling systems. Connector labels and amperage markings provide direct guidance for selecting the correct replacement parts.
- Position A: Starter circuit – 30A
- Position B: Cooling fan – 40A
- Position C: Signal horn – 10A
- Position D: Fuel delivery relay – 20A
- Position E: High beam lights – 15A
Check each terminal for heat damage or oxidation and confirm continuity with a multimeter before replacing any component. Recording connector positions and ratings helps avoid wiring errors and supports consistent electrical operation.
