593902 Relay — Briggs & Stratton OEM Electrical Relay The Briggs & Stratton 593902 Relay is a genuine OEM replacement electrical relay designed to control high-current circuits within the engine and equipment electrical system. Relays play a critical role in safely switching power to components such as the starter circuit, fuel system, charging accessories, or other electrical loads. This OEM relay helps ensure reliable operation and proper electrical performance on compatible Briggs & Stratton small engines used in riding mowers, garden tractors, and outdoor power equipment. Product Details Item Number: 593902 Brand: Briggs & Stratton Part Type: Relay / Electrical Relay Design: OEM high-current switching relay for engine equipment circuits Condition: New Genuine OEM Replacement Part Voltage System: Designed for 12 V electrical systems Application: Controls starter, ignition, fuel, or accessory circuits (model-specific) Typical Dimensions: Varies by relay configuration and mounting style Function This relay is engineered to: Act as an electrical switch to control high-current loads safely Support reliable starter engagement and engine electrical operation Reduce strain on ignition switches by routing power through relay contacts Replace faulty relays causing no-start, intermittent electrical issues, or accessory failure Provide OEM-correct electrical performance and connector fit Verify Fitment Before Ordering Before purchasing, confirm: Part number 593902 matches your engine or equipment parts diagram Relay terminal layout and connector style match your original relay Your equipment uses a 12 V electrical system requiring this relay type ⚠️ Relays may look similar but vary in amperage rating and terminal configuration — always verify correct OEM part number before ordering. Compatibility This OEM relay is commonly used on select Briggs & Stratton engines and equipment such as: Riding lawn mower and garden tractor electrical systems Engines with electric start and accessory control circuits Equipment requiring OEM relay-controlled power switching (Compatibility is representative — confirm exact fitment through Briggs & Stratton parts lookup.) Installation / Usage Disconnect the battery before servicing electrical components. Locate the relay in the wiring harness or electrical panel area. Unplug the old relay carefully from its connector or mounting bracket. Install the new 593902 relay in the same position. Reconnect wiring securely and ensure proper terminal seating. Reconnect battery and test starter/accessory operation. Verify reliable switching with no intermittent faults. Maintenance Tips Inspect relay terminals for corrosion or loose connections. Keep wiring harness connections clean and dry. Replace relay if clicking occurs without power delivery or if circuits fail intermittently. Check battery condition, as weak voltage can mimic relay problems. Notes / Equivalent Replacements Genuine Briggs & Stratton OEM relay 593902 ensures correct amperage rating, connector fit, and long-term electrical reliability compared to aftermarket relays that may not meet factory specifications.
