If neither does and power and ground to the contactor are good, the contactor is defective.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIf you test the motor directly with jumper cables, remove the wires from the motor studs first and refit the nuts.\u003c\/strong\u003e Leaving them connected creates a dead short to ground through the contactor and wiring, at very high current, which will damage both.\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":43958754246715,"sku":"2994","price":131.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/2608\/6971\/files\/2994-RVU-scaled.webp?v=1786537071","url":"https:\/\/eqsystems.us\/products\/contactor-2994","provider":"EQ Systems","version":"1.0","type":"link"}
