TM 9-2350-277-10 TROUBLESHOOTING TABLES—Continued 0089 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 0095 00). Use outside power source (WP 0022 00) or tow start (WP 0078 00) the carrier. If the cause of slow cranking is not obvious, have unit maintenance troubleshoot the electrical system. 5. ENGINE LABORS, RUNS ROUGH, STALLS, OR DOES NOT PUT OUT FULL POWER. 1. Check to see if engine is getting enough air. Check engine air cleaner restriction indicator (WP 0098 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. Check elevation. The carrier will normally lose power at high elevations (mountain passes or high plateaus). If carrier runs rough or power loss is bad, notify unit maintenance. 6. ENGINE OVERHEATS. C A U T I O N Driving carrier with an overheated engine can damage engine. When ENGINE COOLANT TEMPERATURE GAGE indicates above 230 F (110 C), stop carrier and run engine at 1000–1200 rpm until coolant temperature drops below 230 F (110 C). 1. Check to see if all power plant access panels are in place and mounting clamps are tight. Install power plant access panels (WP 0040 00). 2. If hard running in hot weather, follow the precautions for driving in extreme heat (WP 0074 00). When engine overheats, stop carrier and run engine at 1000 to 1200 rpm until coolant temperature drops below 230 F (110 C). 0089 00-2 Change 3
