5.
IMPROPER GOVERNOR SYSTEM OPERATION - (Cont)
Step 7.
Check for governor actuator output signal between pins N and M of cable plug P1. With pumping
assembly operating, signal should be a positive DC voltage which changes in magnitude when
AUTO 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).
