Check the interior panel under the dashboard first, then inspect the engine compartment unit near the battery to locate all circuit protection elements and relay groups.
Use the cover markings to match each slot with its function, including lighting, ignition, and accessory systems. Typical ratings range from 10A for cabin lights to 30A or higher for motors and high-load components.
If a circuit stops working, inspect the metal strip inside the protective element. A break or darkened section indicates failure. Replace it only with the same amperage value to prevent overheating or wiring damage.
For repeated issues, trace the connected wiring path and check areas exposed to vibration, heat, or movement, such as door hinges and engine bay harness routing.
Exact locations of fuse panels in Delica and access steps
Check the driver side lower dashboard first; the interior panel is mounted behind a small removable cover near the steering column and can be opened by pulling the notch to release clips.
The second panel is located in the engine compartment near the battery inside a sealed plastic housing; press the side tabs and lift the cover carefully to access high-current links and relay units.
Use this quick reference for locations and access:
| Location | Area | Access method |
|---|---|---|
| Interior panel | Under driver side dashboard | Pull cover by notch to release clips |
| Engine compartment unit | Near battery | Press side tabs and lift lid |
Fuse slot layout with circuit assignments and relay positions
Match each numbered slot on the panel cover with its assigned circuit, then confirm amperage printed on the protective element before removal.
Interior panel positions usually handle low and mid load systems such as cabin lighting, radio, and accessory outlets, while the engine compartment unit groups high-load circuits like ignition, cooling fan, and braking control.
Typical amperage distribution helps identify circuits faster: 10A for interior lights, 15A for audio and accessory lines, 20A to 30A for motors, and 40A or higher for main power feeds.
Relay positions are located рядом with high-current slots in the engine bay housing. These control switching for systems like starter motor, fuel delivery, and air conditioning compressor.
Use identical relay units for quick testing by swapping positions with a known working one from the same panel, then checking if the system resumes operation.
If markings are unclear, follow wire color patterns and connector routing from each slot to the component to confirm circuit assignment without full disassembly.
Identifying blown fuses and matching correct amperage ratings
Remove the suspected element and inspect the internal metal strip; a visible break, dark spot, or melted section confirms failure. Use a puller tool to avoid damaging surrounding slots and check the amperage number printed on top before replacement.
Select the correct rating by following these rules:
- Match the exact amperage value printed on the original part
- Do not install a higher rating, as it can overheat wiring
- Use color coding as a quick reference for amperage levels
- Recheck the circuit after installation to confirm normal operation
