It is designed for use in a marine environment and ships as a single unit ready for bench or in-service diagnostic work. Because it is battery powered, it can be used to verify circuit output and component performance without requiring the boat's engine to be running, making it a practical addition to a technician's or boat owner's diagnostic kit. The compact resistor pack is built for straightforward use during troubleshooting of marine ignition and electrical systems, helping isolate whether a component is delivering its rated output under load rather than only at no-load conditions. Its small footprint makes it easy to store aboard or in a toolbox alongside other marine diagnostic equipment. The Sierra 18-99541 is sold as a single item and is intended for marine applications where confirming proper electrical load performance is part of routine diagnostic procedure.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-99541\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Pack Load Resistor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Marine Diagnostic Tool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source:\u003c\/strong\u003e Battery Powered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 12.2 centimeters H x 9.4 centimeters L x 11.0 centimeters W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282394714\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironment Rating:\u003c\/strong\u003e Designed for use in a marine environment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99541 Pack Load Resistor used for?\u003c\/strong\u003e It is used to apply a simulated electrical load when diagnosing marine ignition and electrical components, letting a technician confirm output performance under load rather than only at no-load conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99541 battery powered?\u003c\/strong\u003e Yes, the Sierra Pack Load Resistor 18-99541 is battery powered, so it can be used for diagnostic testing without needing the boat's engine running.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many units come in a package?\u003c\/strong\u003e The Sierra 18-99541 Pack Load Resistor ships as a single item, with one resistor pack per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the weight of the Sierra 18-99541?\u003c\/strong\u003e The Sierra Pack Load Resistor 18-99541 weighs 0.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the Sierra 18-99541?\u003c\/strong\u003e The packaged Sierra 18-99541 measures 12.2 centimeters high by 9.4 centimeters long by 11.0 centimeters wide.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra Pack Load Resistor rated for marine use?\u003c\/strong\u003e Yes, the Sierra 18-99541 is designed for use in a marine environment, making it suitable for diagnostic work aboard boats or in marine service settings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-99541 require installation into the boat's wiring?\u003c\/strong\u003e It is a diagnostic accessory used to apply a load during testing rather than a permanently installed component; specific step-by-step wiring instructions are not included in this listing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the Sierra 18-99541 Pack Load Resistor made?\u003c\/strong\u003e The Sierra 18-99541 Pack Load Resistor is manufactured in the United States.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99541 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-99541 is Sierra's own manufacturer part number for this Pack Load Resistor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of tool is the Sierra 18-99541?\u003c\/strong\u003e The Sierra 18-99541 is classified as a marine diagnostic tool, specifically a pack load resistor for electrical\/ignition testing.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988445999323,"sku":"SIE-18-99541","price":28.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-511-9775_lg__49398.1558111905.500.750.jpg?v=1785187995","url":"https:\/\/www.goodvibesmarina.com\/products\/pack-load-resistor-for-marine-ignition-systems-sierra-18-99541-diagnostic-load-resistor","provider":"Good Vibes Marina","version":"1.0","type":"link"}
