Rated at 30 volts AC\/DC and 5 amps, this 20-inch yellow jumper allows technicians to quickly bridge terminals during troubleshooting without the need for alligator clips or manual probes. The magnetic tip design secures the lead to recessed terminals, keeping both hands free while testing circuit continuity, verifying 24-volt control signals, or isolating faults across thermostats, control boards, and related low-voltage components. It is a standard diagnostic tool carried by HVAC service technicians.\u003c\/p\u003e\n\u003cp\u003eThe MAG1YL is suited for residential and light commercial HVAC service work where low-voltage control circuits require isolation and testing. Typical applications include jumping thermostat terminals to test furnace sequencing, air handler operation, or cooling calls at the air conditioning unit. The magnetic tip makes it especially practical at recessed terminal strips found on control boards and alarm panels where standard clip leads lose contact. Compatible applications listed include thermostats, control boards, sensors, switches, and alarm panels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMagnetic tip design seats firmly on recessed terminals without slipping\u003c\/li\u003e\n  \u003cli\u003eRated 30 volts AC\/DC and 5 amps for safe use on standard low-voltage HVAC control circuits\u003c\/li\u003e\n  \u003cli\u003e20-inch length provides reach across most service panels and terminal boards\u003c\/li\u003e\n  \u003cli\u003eYellow color coding aids in lead identification during multi-point diagnostics\u003c\/li\u003e\n  \u003cli\u003eIdeal for jumping thermostat terminals to isolate control circuit faults\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with thermostats, control boards, sensors, switches, and alarm panels in low-voltage HVAC and building control applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis test lead is used by licensed HVAC technicians during diagnostic service calls and does not require permanent installation. Before applying the jumper, verify the circuit voltage does not exceed the 30-volt AC\/DC rating. Use only on de-energized terminals when the system or component being tested requires power-down before contact. Remove the jumper and restore all original wiring and terminal connections before returning the system to normal operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 30 volts AC\/DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Thermostat, Control Board, Sensor, Switch, Alarm Panel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MAG1YL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS","offers":[{"title":"Default Title","offer_id":51283963216178,"sku":"MAG1YL","price":23.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277798.jpg?v=1781064354","url":"https:\/\/voomisupply.com\/products\/mars-mag1yl-magnetic-thermostat-test-lead-jumper-20in","provider":"Voomi Supply","version":"1.0","type":"link"}
