Open the engine compartment and locate the power distribution center near the battery, then compare each numbered slot with the circuit chart before replacing any blown element. Use a multimeter to verify voltage on both terminals to avoid replacing parts that are still functional.
The electrical layout in this pickup separates high-load systems such as cooling fans, ABS, and starter circuits into dedicated protected lines. Amperage ratings typically range from 20A to 60A depending on the component, with relays controlling major systems like fuel delivery and ignition.
Inspect terminal connections and contact surfaces inside the power distribution center for corrosion, heat marks, or loose fittings. Poor connections can interrupt current flow without visible damage. Disconnect the battery before handling components and ensure all replacements match original ratings to prevent overload.

Locate the engine bay power distribution center near the battery and match each numbered slot with the circuit chart before testing any component. Check voltage with a multimeter on both terminals to confirm whether the protective element has failed or the issue lies elsewhere.
This panel manages high-load systems, each assigned to specific slots with defined amperage values. Typical circuits include cooling fans, ABS module, starter relay, and ignition control, with ratings often ranging from 30A to 60A depending on load requirements.
Use the printed layout inside the cover to identify each circuit quickly, as it lists slot numbers alongside component names. This reference reduces guesswork and prevents incorrect replacements that could damage electrical components.
Trace conductor paths from the distribution center to connected systems, paying attention to relay positions that control switching functions. Relays are often grouped рядом with high-current slots and labeled for quick identification.
Inspect terminals, connectors, and surrounding wiring for heat damage, oxidation, or looseness. Clean contact points and ensure secure connections to maintain stable current flow across all major systems.
How to Locate Under Hood Fuse Box in 2015 Ford F150 Engine Bay
Open the front compartment and look to the right side near the battery; the main power distribution unit is secured in a black plastic housing with a removable cover. Press the locking tabs on both sides to access internal components.
Identify the unit by its position and wiring density; it has multiple thick cables connected directly from the battery and routed toward major systems like cooling fans and ignition modules.
Use the following visual cues to confirm the correct housing:
- Rectangular plastic enclosure with snap-on lid
- Located close to battery terminals
- Multiple high-gauge wires entering from one side
- Label or schematic printed inside the cover
Remove the cover carefully by pressing the side clips and lifting upward; avoid using excessive force to prevent breaking the retaining tabs. The internal layout becomes visible once opened.
Inside, slots and relays are arranged in a grid pattern. Each position corresponds to a specific circuit, such as starter control, ABS, or radiator fan. Numbers and labels molded into the plastic base help match each slot with its assigned function.
Check for a secondary distribution unit near the firewall or driver-side fender; some configurations include an additional smaller housing for auxiliary circuits and relays.
Ensure the ignition is off and disconnect the negative battery terminal before handling components. This prevents accidental short circuits and protects sensitive electrical modules during inspection.
