Where is the ACC wire on a motorcycle?
1 Answers
The ACC wire on a motorcycle is located under the handlebar. The ACC wire refers to the positive terminal of the battery connected through the ignition switch (the switch that requires inserting a key to start the vehicle). When the switch is turned on, it provides positive power, and when turned off, it cuts off the power. The purpose of connecting the ACC wire is to determine whether the motorcycle is in a powered-on or powered-off state. When the key switch is turned on, the motorcycle is powered, and the ACC wire has electricity. When the key switch is turned off, the motorcycle is not powered, and the ACC wire has no electricity. The full English name of ACC is "Adaptive Cruise Control," which means "adaptive cruise control" in Chinese. The adaptive cruise control system is an intelligent automatic control system developed based on the existing cruise control technology. Essentially, it refers to the motorcycle's key switch. Reasons for low ACC voltage: The transformer capacity is too small, and the load exceeds the transformer capacity by too much, causing voltage drop; The wire cross-sectional area is too small, and the load exceeds the wire's rated current by too much, causing high temperature and voltage drop; The wire is too long, and the cross-sectional area is insufficient, causing excessive voltage loss and voltage drop; Unbalanced three-phase current, poor connections in wires, switches, or contact points, etc.
