When facing lighting issues on the Kobelco EX60-5, it's essential to perform a thorough troubleshooting process. Below are some common steps to diagnose and fix the problem:
1. Inspect the Bulbs
The first step in troubleshooting any lighting issue is to check the light bulbs. Burnt-out bulbs are one of the most common causes of lighting failures. To replace a bulb:
- Turn off the machine and disconnect the battery to ensure safety.
- Remove the bulb cover or housing to access the bulb.
- Inspect the bulb for any signs of damage, such as a broken filament or blackened glass.
- If the bulb is burnt out, replace it with a new one of the correct type and wattage.
Blown fuses can cause the lights to stop working entirely or cause dimming or flickering. Fuses are typically located in the fuse box, which may be in a compartment near the operator's station or within the engine bay. To check the fuses:
- Locate the fuse box and refer to the fuse diagram to find the fuse corresponding to the lighting system.
- Remove the fuse and inspect it visually. If the metal strip inside is broken, the fuse is blown and needs to be replaced.
- Always replace fuses with the exact amperage rating to avoid overloading the circuit.
Faulty wiring or loose connections are common culprits behind lighting malfunctions. Over time, wiring may deteriorate due to exposure to the elements, vibration, or corrosion. Here's how to inspect the wiring:
- Check all visible wiring connected to the lights. Look for frayed, broken, or exposed wires.
- Tighten any loose connections to ensure that the electrical circuit is complete.
- If there is visible corrosion, use a wire brush or cleaning solution to clean the terminals.
- If the wiring appears damaged, it may need to be replaced. Be sure to use insulated wire rated for the excavator’s electrical system.
If the bulbs and fuses are intact, but the lights still aren't working, the issue could lie with the switch or relay. The lighting switch controls the on/off function of the lights, and a relay controls the flow of current to the lights.
