Does the Santa Fe cigarette lighter have current limiting?
2 Answers
The Santa Fe cigarette lighter has current limiting. The cigarette lighter is a component found in all vehicles, designed to provide a flame source for smokers. Commonly referred to cigarette lighters can be divided into those that draw power from the vehicle's electrical system. Some manufacturers produce cigarette lighters not for lighting cigarettes but solely for drawing power from the vehicle, which are also known as cigar lighters. The method for removing and installing the cigarette lighter is as follows: 1. Unscrew the housing: For some vehicles, the cigarette lighter socket has a screwed-on housing at the back, which can be unscrewed by turning it counterclockwise and reinstalled by turning it clockwise; 2. Remove screws: For some vehicles, the cigarette lighter socket is secured with screws at the back. Simply use a wrench to remove the screws to take it off, and reinstall it by screwing the screws back in; 3. Remove the panel: Remove the gear shift lever panel, which is attached with plastic clips. You can pry one side up by hand or with a flathead screwdriver to detach the entire panel; 4. Remove panel screws: After removing the gear shift lever panel, the cigarette lighter panel door will automatically open, revealing two black screws. Use an M4 hex key to remove them; 5. Remove the panel box: Pull the plastic panel box of the cigarette lighter out by hand. When it's pulled out about 10 centimeters, disconnect the wiring harness before pulling the entire box out; 6. Operate the inner and outer rings: The cigarette lighter consists of an outer and inner ring. Press the inner ring in to use it. Once it reaches a certain temperature, the inner ring will automatically return to its original position, at which point you can pull it out by holding the outer ring.
I stepped on a landmine last time when I went camping with my Santa Fe! As soon as I plugged in the 150W electric cooking pot, the cigarette lighter suddenly cut off. Later, I checked the manual and found it clearly stated a current limit of 15A (about 180W), and exceeding that would blow the fuse. The 4S shop technician said most Hyundai vehicles are designed this way, with the fuse located in the fuse box on the left side of the steering wheel, and it's a 20A mini fuse. They recommended not using appliances over 120W. I later bought a splitter before daring to use both a phone charger and a car fridge at the same time. Modifying high-power circuits really requires professional help.
