Product Overview
Intermittent starting or accessory operation, a circuit that works only after tapping the relay, or a no-power condition downstream of a known-good fuse can point to a worn relay. Because the same relay may serve different circuits by model, the original part number should be matched before ordering.
This 12-volt replacement restores the switching function handled by John Deere relay GY20437. It is useful when testing isolates the fault to the relay rather than the switch, wiring, fuse or component being powered.
