TM 9-2350-261-10 TROUBLESHOOTING TABLE — Continued 0074 00 MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 4. ENGINE CRANKS TOO SLOW TO START. 1. Check to see if battery cable connections are clean and tight, and battery water is up to correct level (WP 0085 00). Use outside power source (WP 0027 00) or tow start (WP 0065 00) the carrier. If the cause of slow cranking is not obvious, have unit maintenance troubleshoot the electrical system. 2. If temp erature is colder th an -25 F (32 C) check to see if engine disconnect lever is engaged (WP 0026 00). C A U T I O N Never try to move the engine disconnect lever when the engine is running. Do not leave engine disconnected more than 10 minutes. Damage to the transfer gearcase can result. Disengage the engine disconnect lever (WP 0026 00). If engine still cranks too slowly, record fault on DA Form 2404 and notify unit maintenance. 5. ENGINE LABORS, RUNS ROUGH, STALLS, OR DOES NOT PUT OUT FULL POWER. 1. Check to see if engine is getting enough air. Check air cleaner restriction indicator (WP 0004 00). If indicator shows only red in the window, notify unit maintenance. 2. Check to see if there is water in the fuel. Drain primary and secondary fuel filters (WP 0090 00). 3. High elevation operation. The carrier will normally lose power at high elevations (mountain passes or high plateaus). If carrier runs rough or has a power loss, push air control valve in (WP 0028 00) to draw cooler air from rear compartment and increase horsepower. If carrier runs rough or without much power, notify unit maintenance. 6. ENGINE OVERHEATS. 1. Check to see if all power plant access panels are in place and mounting clamps are tight. C A U T I O N Driving carrier with an overheated engine can damage engine. When ENGINE COOLANT TEMPERATURE GAUGE indicates above 230 F (110 C), stop carrier and run engine at 1000–1200 RPM until coolant temperature drops below 230 F (110 C). Install panels (WP 0048 00 and WP 0049 00). 0074 00-2 º º º º º º
