How it works:
* Power Source: The lighter's circuit is connected to the vehicle's electrical system, typically drawing power directly from the battery through a fuse.
* Heating Element: Inside the lighter is a resistive heating element. When you push the lighter in, it completes the circuit, allowing electricity to flow through the element.
* Heat Generation: The resistance of the element causes it to heat up, eventually glowing red-hot. This heat is what ignites the lighter's filament.
Why it might not be working:
Several reasons can explain a malfunctioning lighter:
* Blown Fuse: This is the most common cause. Check your owner's manual for the fuse location and rating for the lighter circuit. Replace the fuse if it's blown.
* Loose or Corroded Wiring: Connections at the lighter socket itself, or along the wiring leading to it, can become loose or corroded over time. Inspect these connections and clean them with a wire brush or contact cleaner if necessary.
* Faulty Lighter: The lighter itself could be broken. The heating element might be burned out or the internal mechanism might be jammed. Replacing the lighter is the solution in this case.
* Power Outlet Issue: If the outlet itself is faulty, it won’t deliver power to any device plugged into it. Test with a multimeter.
* Wiring Issues: The wiring between the lighter and the fuse box could have a break. It would require inspection and repair.
Troubleshooting Steps:
1. Check the Fuse: This is the first and easiest step.
2. Inspect the Wiring: Look for any visible damage to the wiring or loose connections.
3. Test the Lighter Socket: Use a multimeter to see if the socket is receiving power when the lighter is inserted.
4. Try a Different Lighter: If you have another lighter, try using it in the socket. This helps determine if the issue is with the lighter itself or the socket.
If you're not comfortable working with car electrical systems, it's best to take your Ranger to a qualified mechanic for diagnosis and repair.
