This is a genuine OEM sourced replacement part designed for use with Homelite and Ryobi chainsaws. The ignition module also known as armature-magneto provides current for the ignition system by producing pulses of high voltage for the spark plugs. While there are various reasons for ignition module failure, the primary symptoms usually manifest in the form of extreme difficulty starting your equipment, and eventually, a no-start condition. It is a complete kit which includes a metal ignition module, rubberized lead wire, spark plug and two screws to secure it.
