TM 10-4320-315-24Table 2-2. Troubleshooting Procedures - (Cont)MALFUNCTIONTEST OR INSPECTIONCORRECTIVE ACTION5.IMPROPER GOVERNOR SYSTEM OPERATION - (Cont)Step 7.Check for governor actuator output signal between pins N and M of cable plug P1. With pumpingassembly operating, signal should be a positive DC voltage which changes in magnitude whenAUTO THROTTLE (ASA) is turned.If signal is correct, replace governor actuator (para. 2-30).If signal is not correct, change governor control module (para. 2-27) and if that doesn't work, change pressure control module (para 2-26).6.ENGINE OVERHEATING.Check V-belt tensioner assembly for proper tension.Replace V-belt tensioner if damaged (para. 2-44).Section VI.
