Universal Motorcycle complete wiring systems for bm 125

The wiring system of a Bajaj Boxer BM 125 is a 12-Volt (AC/DC) electrical system designed for reliability, handling urban commuting, light cargo, and basic features like electric start, fuel gauge, and indicators. Its harness uses EPDM or rubber insulation for durability against environmental factors, and high-quality brass or copper connectors ensure secure electrical pathways and minimal signal loss. The system powers the headlamp, tail lamp, turn signals, speedometer, and horn, providing essential functionality for daily use. 

Key Features & Components

12-Volt (AC/DC) Electrical System: Powers all the bike's electrical components, offering flexibility in power source for different functions. 

EPDM Rubber Insulation: Provides excellent resistance to UV rays, ozone, heat, and other environmental elements, ensuring long-term durability for the wiring harness. 

High-Quality Connectors: Made from materials like brass or plated copper to resist corrosion and oxidation, ensuring a secure electrical connection with minimal signal loss. 

Integrated Lighting: Features a 35/35W headlamp with an optional pilot lamp, a 5/21W tail/stop lamp, and 10W side indicator lamps for visibility and safety. 

Advanced Instrumentation: The instrument cluster includes a fuel gauge, service indicators, and a speedometer with its own indicator lamp. 

Electric Start & Self-Diagnostic Systems: Modern versions often include an electric starter, though self-start functionality may require the bike to be in neutral. 

Reliability for Diverse Conditions: Engineered for reliability and safety, the system is built to perform well under various riding conditions. 

How It Functions

Power Transmission: The wiring harness acts as the motorcycle's "nervous system," transmitting power from the battery and charging system to operate the lights, ignition, and control systems. 

Signal Communication: It also transmits control signals, such as from the switches to the turn signals or the starter button to the starter motor. 

Maintenance & Longevity: Regular maintenance of the electrical system, including checking bulbs and connections, is essential for long-term dependability.
