Multiquip 31510ZE1811 Lamp Coil (12V/25W)

The Multiquip 31510ZE1811 Lamp Coil (12V/25W) is a genuine OEM component designed for GA, GAW, and GAC series gasoline-powered generators and arc welders, including the GAC2.5HR, GA3.6HR, GA2.5HR, GAW180HE, GAW180HE1, GAW180HEA, GA9.7HE, GA6HEB, GA6HB, GA3.6HA, GA3.6HZ, GA6HZ, and GAC2.2HZ. As a direct Multiquip OEM part, the 31510ZE1811 is manufactured to the same specification as the original, ensuring a correct drop-in fit with no guesswork on compatibility. Sourced through DHS Equipment's authorized Multiquip parts supply, this coil is the right call when your generator or welder's lamp circuit needs restoring. Confirm your model code before ordering to ensure this is the right match for your unit.

Key Features

• Correct Voltage and Wattage Rating — Matched to the 12V/25W lamp circuit spec of the original Honda GX240/GX340-powered units, maintaining proper lamp output without over- or under-driving the circuit.
• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, so winding resistance and magnetic output remain within the spec range that the GX240/GX340 ignition system expects.
• Direct-Fit Replacement — Mounts and connects to the original lamp coil position on supported models; no reworking of the mounting bracket or wiring harness required.
• Broad Series Coverage — Fits GAC2.5HR, GA3.6HR, GA2.5HR, GAW180HE, GA9.7HE, GA6HEB, GA3.6HA, GA3.6HZ, GA6HZ, GAC2.2HZ, and related variants in the GA and GAW families.
• Electrical System Integrity — A failed lamp coil leaves indicator or work lighting inoperative; replacing it with the correct OEM unit restores the full electrical function the machine was built to deliver.

The lamp coil is a small magneto-mounted generating coil that produces the low-voltage AC current needed to power the unit's lamp circuit independently of the main alternator output. On Honda GX240- and GX340-powered generators and arc welders, this coil sits on the engine's stator assembly and generates current as the flywheel rotates. When the coil degrades or fails — through heat cycling, vibration fatigue, or winding breakdown — the lamp circuit loses power entirely, leaving work lighting or indicator lamps dark. Replacing the coil with the correct 12V/25W-rated part restores full lamp circuit function and ensures the electrical load on the stator remains balanced as the engine manufacturer intended.
