Keyed switchgear is offered specifically to prevent unauthorized use of a lifting system, which matters on a trailer left unattended.\u003c\/p\u003e\u003ch4\u003eHow it sits in the circuit\u003c\/h4\u003e\u003cp\u003eBattery voltage reaches the key switch from the battery terminal on the motor solenoid. Turning the key on passes that voltage through to the center terminals of the rocker switch. With the key off, pressing the rocker does nothing. Not every system was built with a key switch.\u003c\/p\u003e\u003ch4\u003eDiagnosing a dead system\u003c\/h4\u003e\u003cp\u003eCheck for battery voltage at one key switch terminal first. If there is none, trace the wiring back through the harness to the pump. If voltage is present but does not pass through when the key is turned on, the tumbler is the fault. Supplied with two keys.\u003c\/p\u003e\u003ch4\u003eDocuments\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/TS-Single-leg-Trailer-Jacks-AM-AJ-single-manufactured-after-2007.pdf\" target=\"_blank\"\u003eSingle Leg Trailer Jack Troubleshooting Guide (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Switchgear-Chart-TM.pdf\" target=\"_blank\"\u003eSwitchgear Replacement Chart (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/EQS03R11-EQ-Systems-Trailer.pdf\" target=\"_blank\"\u003eEQ Systems Lifting Systems for Any Size Trailer (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EQ Systems","offers":[{"title":"Default Title","offer_id":43958751625275,"sku":"7463","price":28.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/2608\/6971\/files\/7463-RVU-scaled.webp?v=1786537030","url":"https:\/\/eqsystems.us\/products\/key-tumbler-7463","provider":"EQ Systems","version":"1.0","type":"link"}
