The Wacker Neuson 5100030661 Wiring Harness Low Coolant is a genuine OEM component designed for the G1100 Generator. Sourced directly from Wacker Neuson, this harness is built to match the exact connector layout, wire gauge, and routing path of the original, ensuring the low coolant detection circuit integrates seamlessly with the generator's protection system. It is the correct replacement when the factory harness shows damage, corrosion, or signal failure that triggers false warnings or prevents the coolant sensor from communicating properly with the control panel.
Key Features
- OEM-Matched Signal Integrity — Engineered to the original wire gauge and connector specifications, so the low coolant sensor delivers accurate readings to the control system without interference or voltage drop.
- Direct Connector Compatibility — Plug-and-play replacement that connects to the existing sensor and control panel terminals on the G1100 without modification to the harness routing or mounting points.
- G1100 Generator Fitment — Purpose-built for the Wacker Neuson G1100 portable generator; part number 5100030661 confirms an exact application match.
- Protects the Engine from Coolant Loss Damage — A functioning low coolant harness ensures the protection circuit can shut the generator down before overheating causes internal engine damage — a failed or corroded harness removes that safeguard entirely.
- Corrosion-Resistant Connections — As a genuine OEM harness, terminal materials and sealing meet Wacker Neuson's original specifications for resistance to moisture and vibration in portable power applications.
The low coolant wiring harness carries the electrical signal from the coolant level sensor to the generator's control board, alerting the system when coolant drops below a safe operating threshold. This signal triggers a protective shutdown before the engine reaches temperatures that cause serious internal damage. When the harness is broken, corroded, or shorted, the low coolant warning may fail to activate — or may trigger continuously — leaving the engine unprotected or the generator unusable. Replacing a damaged harness with the correct OEM part restores full function to the engine protection system.
