What are the symptoms of a faulty motorcycle ignition coil while riding?
2 Answers
When a motorcycle's ignition coil is faulty, symptoms during riding include incomplete combustion, lack of power, increased fuel consumption, and even failure to start. Below is relevant information about motorcycle ignition coils: 1. Overview: The motorcycle ignition coil, also known as the spark coil, consists of a primary coil, secondary coil, and iron core. 2. Working principle: During operation, the primary coil is first charged, inducing a self-generated voltage of 200-300V; then mutual induction with the secondary coil produces a high voltage of 18-20kV, with the voltage magnitude determined by the turns ratio between the two coils; finally, the high voltage is delivered to the spark plug for ignition.
As a seasoned motorcycle rider, I've encountered situations where the ignition coil failed. That time, while riding on a mountain road, I suddenly felt the bike was particularly hard to start, requiring repeated throttle kicks to barely get it running. After moving, the engine kept jerking, as if being held back by something, especially lacking power during acceleration, and even nearly stalled on a flat stretch. Such symptoms often accompany abnormal spark plug ignition, causing the bike to lose stability. Upon inspection, it turned out the ignition coil was severely leaking electricity. It's advisable to regularly check for aging of the coil's connecting wires to avoid breaking down on the road. Prolonging such issues can easily damage other components, like the charging system. If such a malfunction occurs, it's best not to push through; instead, pull over and seek help for repairs to avoid further complications.
