Contact dealer or visit www.northern-lights.com for most current installation drawings. 1. Based on SAE J1995 and ISO 3046. 2. Actual fuel consumption will vary depending on operating conditions Engine Block • Four cycle, 3 cylinder, liquid cooled, naturally aspirated, overhead valve diesel. • Swirl combustion chambers improve fuel efciency and reduce smoke. • Glow plugs for quick cold starting. Cooling System • Freshwater cooling system in heat exchanger or keel cooled configuration. • One-piece heat exchanger, expansion tank and liquid cooled exhaust manifold. Fewer troublesome hoses and gaskets. Cast iron to resist corrosion and electrolysis. • Heat exchanger cooling is standard. Cupro-nickel tube-type heat exchanger has removable ends for easy cleaning. Rubber impeller seawater pump of bronze and stainless steel is gear driven; no belt. Fuel System • Fuel system is self-venting. • Injection pump with 5% mechanical governor for close AC frequency control. • Pintle injectors with replaceable tips. • Mechanical lift pump with hand primer. No electric pump to fail. • Large spin-on fuel lter. • Flexible fuel lines routed to fuel manifold. • Stop solenoid controls the fuel rack, not the throttle, to eliminate speed variances and linkage problems. • Meets US EPA Tier III emission standards at date of manufacture. • Washable air cleaner in cast intake manifold reduces intake noise. • Cast iron, wet exhaust elbow for safety. Lubrication System • Full ow, spin-on oil lter with bypass. • 4.2 qt (4 ltr) oil capacity for better lubrication. 200 hour oil change intervals. • Oil drain for quick, clean oil changes. • Closed crankcase vent system traps oil vapor and keeps engine room clean. M843NW3 Features and Benefits DC Electrical System • DC system uses reliable relays instead of an unrepairable printed circuit board. • 12 volt starter motor and battery charging alternator with regulator and belt guard. • Standard panel: Remote mount S-1B has hour meter, stop-start switch with run light and preheat switch. • Expandable to six panels up to 110 feet from the set. • 20 foot (6m) plug-in panel harness lets you mount your panel anywhere onboard. Better than inaccessible unit mount panels that are prone to vibration problems. • Low oil pressure, high coolant temp and high exhaust temp safety shutdowns standard. • Northern Lights, direct coupled, brushless AC generator is maintence free. 4 lead, 1 phase, 50 or 60 Hz output standard. 12 lead, 3 phase optional. Conservative heat rise rating: 95oF/50oC ambient. • Automatic voltage regulator (AVR) is powered by dedicated AC winding for true 300% short circuit capability and circuit breaker protection. Quick ±1% RMS no load to full load voltage regulation. • Generator features high quality, Class “H” epoxy insulation, accessible diodes, over-sized bearings and junction box for wiring. Special Equipment • Welded steel base frame with drip pan. • Four plateform mounts isolate vibration. • White, long-life polyurethane paint. • Operator’s and parts manuals standard. Classification Standards • Consult factory for details. www.northern-lights.com Northern Lights, Inc. • 4420 14th Ave. NW., • Seattle WA 98107 Tel: 206-789-3880 • 1-800-762-0165 • Fax: 206-782-5455 Information and dimensions subject to change without notice.
