BYD Shark 6 Fuse Box Diagram: All Three Boxes, Located and Explained
The BYD Shark 6 carries three fuse boxes per the manual: the under-hood box beside the left fender of the engine compartment, the dashboard box in the shield under the dash, and a positive fuse box under the rear seat above the low-voltage battery. The per-fuse assignments live on the label under the under-hood box's cover, and one rule is absolute: never fit a fuse of higher amperage, as the manual warns of serious damage or fire.
Shark 6 Fuses at a Glance
| Measurement | Detail |
|---|---|
| Under-hood box | Beside the left fender of the engine compartment |
| Dashboard box | In the shield under the dashboard |
| Positive fuse box | Under the rear seat, above the low-voltage battery |
| The assignments | On the label under the under-hood cover |
| The iron rule | Never a higher amperage, never a substitute object |
Box 1: Under the Hood, Beside the Left Fender
Pop the bonnet and look to the left fender side of the engine compartment. The manual's procedure is refreshingly simple: remove the fuse box's upper cover and turn it over, because the fuse label, the actual per-position diagram for your build, is printed on its underside. That label is the authoritative map, matched to your vehicle's exact configuration, which is why the manual points you to it rather than printing one generic table.
This box is your first stop for engine-bay and exterior circuits, and the only one of the three designed for owner-level checks in the driveway.
Box 2: Under the Dashboard, Behind the Shield
The dashboard fuse box lives in the shield under the dash on the driver's side. Reaching it means removing trim in a cabin dense with airbag wiring and connectors, which is why we file this one under dealer territory: if a cabin circuit points here, let the workshop open it while you keep the warranty position tidy.
Box 3: The Positive Fuse Box Under the Rear Seat
The Shark 6's third box is the one most owners never hear about: a positive fuse box under the rear seat, directly above the low-voltage battery, protecting the main feeds at their source. You will meet this neighbourhood anyway, because the 12-volt battery lives there too, as our Shark 6 12V battery and jump start guide covers, and the same advice applies: high-current main fuses are professional work, not pliers work.
The Safety Rules, Straight From the Manual
- Never a higher amperage: The manual is explicit that over-rated fuses, or any other object in a fuse's place, can cause serious damage or even fire
- Match like for like: A blown 15 amp fuse gets a 15 amp fuse, and nothing else
- Power down first: Vehicle off before pulling anything, and hands off anything orange, which is high-voltage territory
- Repeat offenders see the dealer: A fuse that blows twice is protecting you from a fault, not inconveniencing you
Symptom-to-Box Triage
| Measurement | First suspect |
|---|---|
| One exterior light or horn dead | Under-hood box, check the label position |
| 12V accessory socket or USB dead | Under-hood label first, then dealer for the dash box |
| A cabin convenience dead (screen, seat, window) | Dashboard box, dealer territory |
| Widespread electrical oddness | Positive box or 12V battery, professional inspection |
| Warning lights with the fault | Read the cluster first, per our warning lights guide |
Checking a Fuse the Right Way
- Power the vehicle off and open the bonnet
- Lift the under-hood cover and flip it to read the label's map
- Find the suspect position for the dead circuit
- Pull it with the fuse puller or small pliers, straight up, and inspect the wire through the window, a broken strand means blown
- Replace with the identical rating, press home, and test the circuit
- Stop at strike two: a repeat blow ends the DIY and starts the dealer visit
A small assortment of spade fuses in common ratings earns its glovebox space, sized to the ratings your own label shows across its rows, and it belongs in the same kit as your monthly once-over from our DIY maintenance checks guide.
Common Mistakes
- Fitting the next size up: The manual's fire warning exists for exactly this
- Foil, wire, or bolts in the slot: Any other object is the manual's own phrase, and its own prohibition
- Prying at the dash shield: Airbag country, leave it to the workshop
- Ignoring the underside label: The real diagram for your build is printed on the cover you just removed
- Forgetting the third box exists: Main-feed faults live under the rear seat
- Treating repeat blows as bad luck: They are a fault announcing itself
