Chevrolet Spark (M300) 2010-2015 fuse box and relay Diagrams
The Chevrolet Spark (M300), produced from 2010 to 2015, is a compact city car known for its nimble handling, efficient fuel economy, and practical design. Despite its small size, the Spark is equipped with a comprehensive electrical system that supports a variety of modern features. The fuse box and relays are integral components that ensure the smooth operation of these systems.
The fuse box in the Chevrolet Spark M300 is typically located in the engine compartment and another inside the cabin, usually near the driver’s side dashboard. These fuse boxes protect the car’s electrical circuits by containing fuses that will blow in the event of an overload or short circuit, preventing damage to critical components like the engine management system, lighting, and infotainment.
Relays in the Spark are responsible for controlling high-power circuits, such as those for the starter motor, fuel pump, and cooling fans. These relays act as switches, allowing high-current devices to be operated safely by lower-power control circuits. Regular inspection of the fuses and relays is crucial for maintaining the vehicle’s electrical integrity, preventing minor issues from escalating into more significant problems.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
