PREMIUM EARTH Kiwami - Application: For 97 Alto - Material: Braided wire - Accessories: 2 washers New A new proposal for those seeking improved performance and fuel efficiency through earth tuning. Commonly, grounding involves connecting the negative terminal of the battery to an earth point. However, consider this: What happens if you disconnect the battery while the engine is running? Those with some knowledge will know immediately. That's right, the engine doesn't stop. This is because after the engine starts, most of the car's electrical components are powered by the electricity generated by the alternator. The alternator's ground is the engine itself. You should understand what I'm getting at by now. Many of the vehicle's electrical components are grounded to the body and return to the negative terminal of the battery and the engine via the vehicle's metal parts. The negative terminal of the battery is connected to the body. Connecting the ground effectively to the engine itself is more effective than gathering the ground to the negative terminal of the battery.
