Check the interior power distribution panel under the dashboard on the driver side first, as most cabin-related electrical faults originate there. Lighting circuits, instrument cluster, and control switches are typically grouped with ratings between 10A and 20A.
Inspect the engine compartment power center near the battery to access high-load circuits. Cooling fans, ignition system, and charging lines are handled in this section, where higher-rated protection elements are used to manage increased current flow.
Use the printed layout inside the panel cover to match each slot with its function. If the cover is missing, identify circuits by wire color coding and connector placement. Repeated failure of the same protective element or visible heat damage indicates wiring issues or malfunctioning components rather than simple overload.

Use the panel cover chart to match each slot with its assigned circuit before removing any protective element, as incorrect placement can disable multiple systems. Interior distribution panels typically group lighting, dashboard electronics, and accessory power lines.
Check amperage markings next to each slot to ensure proper replacement. Lower values such as 10A or 15A are used for control circuits, while higher ratings above 30A handle motors and high-load components like cooling systems.
Relay Position and Function Mapping
Inspect relays positioned рядом с панелью распределения питания, as they control switching for systems such as fuel delivery, headlights, and radiator fans. Audible clicking during activation indicates the relay coil is engaging and passing current.
Wiring Path Tracking and Fault Detection
Trace circuit routes from the battery through each protection point to the end component using wire color patterns and connector alignment. Voltage drops under load highlight resistance issues, often caused by corrosion, loose terminals, or damaged wiring insulation.
Exact Fuse Box Locations in 3000GT Cabin and Engine Compartment
Check the driver-side footwell under the dashboard to access the interior power distribution panel; remove the plastic cover to expose grouped circuits for cabin systems. This section supports lighting, dashboard indicators, and accessory controls.
Look slightly above the kick panel area near the steering column, as some configurations position the panel higher behind trim pieces that require removal for access.
- Mounted behind a snap-in or screw-secured cover
- Located close to lower dashboard frame
- Includes printed circuit identification inside the cover
Open the hood and locate the main distribution unit near the battery, typically installed along the engine bay side or firewall. This enclosure handles high-current circuits such as cooling fans, ignition system, and charging lines.
Release the locking clips on the cover to access internal slots and relays, which are arranged in rows with amperage labels molded into the housing.
- Follow the positive battery cable to confirm location
- Check for sealed cover to protect against moisture
- Identify relay positions next to high-load circuits
Inspect for additional panels near the passenger side or behind side trim in some versions, where extra circuits for optional equipment may be installed.
