The Chevrolet Bolt EV (2016-2022) stands out with its fully electric powertrain, offering up to 259 miles of range on a single charge. Its key features include regenerative braking, a spacious interior, and advanced driver assistance systems such as lane-keeping assist and automatic emergency braking. The Bolt EV also has a large touchscreen infotainment system with smartphone integration.
The fuse box and relays play crucial roles in maintaining the Bolt EV’s electrical systems. The fuse box, located under the hood and inside the cabin, protects critical components like the battery management system, infotainment, lighting, and climate control from electrical surges. If a fuse blows, the corresponding system loses power until the fuse is replaced.
The relays manage high-current systems, such as the electric motor and charging systems. They act as switches that allow low-power circuits to control the high-power demands of the vehicle’s key components, ensuring the safe operation of the electric drivetrain. A faulty relay can cause issues like charging failures or prevent the motor from functioning properly.
Regular inspection of the fuses and relays is essential to keep the Bolt EV’s advanced features and electric performance running smoothly.

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.
