The Chery Bonus 3, also known as the Chery E3 (A19), produced from 2013 to 2015, is a compact sedan that aimed to deliver affordable transportation with practical features. As with any modern vehicle, its electrical system plays a crucial role in the car’s overall functionality, and the fuse box and relay components are central to this system’s operation.
Fuse Box in the Chery Bonus 3 / E3 (A19)
The fuse box in the Chery Bonus 3 from 2013 to 2015 houses a variety of fuses that protect different electrical circuits within the vehicle. These circuits power essential systems such as the engine control module, lighting (both interior and exterior), the infotainment system, climate control, and other electronic accessories. Each fuse is designed to “blow” or break the circuit if an electrical fault occurs, such as an overload or short circuit, thus preventing damage to more critical and expensive components.
In the Chery Bonus 3, the fuse box is typically located in two primary areas: one inside the cabin, usually under the dashboard, and another in the engine compartment. The interior fuse box manages many of the vehicle’s convenience features, while the one in the engine compartment is more focused on engine and powertrain components.
Relays in the Chery Bonus 3 / E3 (A19)
Relays in the Chery Bonus 3 serve as electronically controlled switches that manage the operation of high-current circuits. These are critical for controlling functions that require significant power, such as the starter motor, fuel pump, air conditioning compressor, and power windows. Relays ensure that these systems receive the necessary electrical power without overloading the smaller switches and wiring in the cabin.
Relays are often found near the fuse box, either in the cabin or the engine compartment, making them accessible for inspection and replacement. They are designed to handle higher currents than fuses, and their role is crucial for the safe and efficient operation of the vehicle’s high-demand systems.
Maintenance and Troubleshooting
Regular inspection and maintenance of both the fuse box and relays are vital to ensuring the smooth operation of the Chery Bonus 3. If any of the vehicle’s electrical components stop functioning—such as headlights, the infotainment system, or the air conditioning—checking the relevant fuses and relays should be the first step in troubleshooting.
Blown fuses should be replaced with ones of the same rating to avoid further electrical issues. Similarly, if a relay fails, it should be replaced promptly to restore the function of the affected system. Ensuring that all connections are clean and free from corrosion will also help prevent electrical problems.
Common Electrical Issues
Owners of the Chery Bonus 3 may encounter common electrical issues such as blown fuses, faulty relays, or corroded connections. Early detection and resolution of these issues are essential to prevent more significant problems. For example, a faulty relay in the fuel pump circuit could lead to starting problems, while a blown fuse in the lighting circuit could result in the loss of headlights.

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.
