Two are used per pump, one for each direction of motor rotation, so a fault in one can leave a system that extends but will not retract, or the reverse.\u003c\/p\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUsed on the following pumps: S100T*5151, S100T*5161\u003c\/li\u003e\n\u003cli\u003eListed as the solenoid for the 2727 and 2754 pump assemblies, which use motor 2751\u003c\/li\u003e\n\u003cli\u003eTwo relays per pump\u003c\/li\u003e\n\u003cli\u003eA direct replacement where 2735 is the existing part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eDiagnosing\u003c\/h4\u003e\u003cp\u003eA system that runs one direction only is the classic symptom. Check for the switch signal reaching both relays before condemning either: the fault is often upstream in the switch, the harness or the control panel. Where the motor will not run in either direction and both relays test good, look at the motor and its cables. These pumps draw heavy current, so a tired battery presents as an electrical fault.\u003c\/p\u003e\u003ch4\u003eDocuments\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Motor-Solenoid-Contactor-Relay-Replacement-Chart-TM.pdf\" target=\"_blank\"\u003eMotor Solenoid, Contactor and Relay Replacement Chart (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/TS-Motor-Solenoid-for-EQ-Hydraulic-Pumps-TM.pdf\" target=\"_blank\"\u003eMotor and Solenoid Troubleshooting for EQ Hydraulic Pumps (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Required-Maintenance-Items-Hydraulic-Systems-EQ-TM.pdf\" target=\"_blank\"\u003eRequired Maintenance Items for EQ Systems Hydraulic Jacks and Slide Systems (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EQ Systems","offers":[{"title":"Default Title","offer_id":43958754312251,"sku":"2735","price":19.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/2608\/6971\/files\/2735-RVU-scaled_57c230ad-c806-4bb6-89ad-43b6ae2810f4.webp?v=1786537072","url":"https:\/\/eqsystems.us\/products\/relay-2735","provider":"EQ Systems","version":"1.0","type":"link"}
