Description
Overview:
This genuine Stihl electrical lead (MPN 4144 440 1901) is a factory-spec replacement for the stop/ignition circuit on selected handheld machines. Built with a durable insulated copper conductor and pre-crimped terminals, it restores a reliable electrical path between the handle switch and the ignition module so the engine starts, runs, and shuts off as intended. Designed for petrol brushcutters and multi-tool powerheads, it provides a precise fit on popular models such as FS 40 and FS 56, along with several related FC, HL, HT, and KM machines. Use it to replace damaged, brittle, or corroded wiring that can cause intermittent cutting out or a non-functioning kill switch. As an OEM part, it matches the original length and connectors for straightforward installation and dependable performance.

Typical Applications:
Replacing a worn or damaged stop/ignition lead on Stihl brushcutters and compatible handhelds. Used to fix issues where the engine will not shut off, is hard to start due to grounding faults, or cuts out intermittently. Ideal during handle, switch, or shaft servicing where wiring has been pinched, chafed, or corroded, helping maintain reliable day-to-day operation.
