REFERENCE INFORMATION
If STUICE-R
is not available, accelerate under full power
to .a safe and reasonable speed on a level surface.
For STUICE-R
test 12. a number higher than 6.700 is
passing.
For test 13. a number higher than 75 is passing.

It is normal for the engine to emit some black smoke
when accelerating after idling for a while. Under most
other conditions, exhaust smoke is usually from one of
three sources;
BLUE smoke is usually oil.
BLACK smoke is too much fuel or too little air (often
caused by advanced injection timing).
WHITE smoke is usually water (often caused by retarded
injection timing).
If the smoking is continuous or appears under a particular
condition, the smoke probably indicates a problem and
should be investigated.
If STEXE-R
is not available, there is no easy
way to test compression.
In this case, go on to
the next step but remember that compression
may be a problem.
ENGINE RUNNING
ENGINE POWER TEST (PERCENT)
STMCE-R TEST 13
1. Set TEST SELECT switches to 13.
2. Press and release TEST button.
3. Wait for prompting message CIP to appear.
4. When CIP appears on display, press down
sharply on engine accelerator and
hold it to the floor. When VIM displays OFF.
release accelerator.
5. A number will be displayed after the
engine has returned to idle speed. This
number is the test result in units of
percent of nominal rated power.
ENGINE POWER TEST (RPM/SEC)
STMCE-R TEST 12
1. Set TEST SELECT switches to 12.
2. Press and release TEST button.
3. Wait for prompting message CIP to appear.
4. When CIP appears on display, press down
sharply on engine accelerator and
hold it to the floor. When VTM displays
a number, release accelerator.
5. A number will be displayed after the
engine has returned to idle speed. This
number is the test result in units of
rpm per second.

COMPRESSION UNBALANCE
STUICE-R TEST 14
I
1. Run tests 72,73, and 74 to verify that the
batteries are ok.
2. THE GLOW PLUG CONTROLLER
AND THE
CONTROL VALVE ELECTRICAL
CONNECTOR
MUST BE DISCONNECTED
PRIOR TO RUNNING THIS TEST.
3. Disconnect wire 64A at injection pump to
prevent starting.
4. Disconnect glow plug controller and control
valve electrical connector (to keep waveform
clean).
6. Start Test 14. compression unbalance.
6. Wait for the GO message. Crank the engine.
7. Release the rotary switch when the VTM
displays OFF. A number less than 25%
is passing.
