Product Overview
The glow plug relay switches battery current to the diesel glow-plug circuit during the preheat cycle. Long cranking or difficult cold starts can occur when the relay does not consistently energize the glow plugs. Replacing the failed component can restore normal operation without changing unrelated parts that are still serviceable.
Fitment can vary by engine build, machine serial number and production revision. Use the model information below together with the original part number, connector or mounting layout when applicable.
