ENGINE DIAGNOSTIC TOOLS Section 4 CREATIVE TOOL MODEL CT-4000 DIESEL TIMING AND TACHOMETER INSTRUMENT (SE-2783) OR (3005A) CURRENT MODEL (Continued) OPERATING PROCEDURES (Continued) 6. Connect the lead (4, Figure 7) provided to couple the tachometer and timing light unit (SE-2783) or (3005A) to the white coaxial cable at the 14 mm Split-Nut Transducer (2, Figure 7). 7. Start the engine.  Check for fuel leaks. 8. Perform the speed and timing checks as follows: (See KEYBOARD DESCRIPTION, this section). a. Depress the "RST" (Reset) key. NOTE:   If     it     is     already     depressed,     release     and depress.  SE-2783 or 3005A should be "powered up" at this point, as indicated by the "- - - -" appearing in the digital display. b. Depress and release the "TST" (TEST) key on  the  keyboard  to  place  the  SE-2783  or 3005A   in   the   operational   mode.      "8888" appearing in the digital display indicates the unit   is   operational   and   a   signal   is   being received from the transducer.  "- - - - -" on the digital display indicates: 1. The transducer is disconnected. 2. The unit is NOT functioning properly. 3. The appearance of any other character or number at this time means the unit is not functioning properly. NOTE:   Once the SE-2783 or  3005A  has  been  placed in the operational mode, any of the functions can be selected. c. Depress  and  release  the  "RPM"  key.    The instrument    is    now    in    the    RPM    mode. Engine    speed    will    be    displayed    on    the digital readout.  Adjust engine speed to 700 RPM   as   shown   in   the   PERFORMANCE DATA GUIDELINES, Section 6. d. Depress  and  release  the  "ADV"  key.    The instrument  is  now  in  the  ADVANCE  mode. Set  ADVANCE  mode  to  double  zero  (00). Depress    "STB-ON"    key    to    activate    the strobe  light.    Aim  the  strobe  light  and  in- crease advance mode (by one increment at a  time)  using  the  "    "  key  until  TDC  mark and  front  cover  pointer  align.      When   the marks  are  in  alignment,  release  the  "    " key.  The actual timing will be shown on the display. IMPORTANT WHENEVER CHANGING ENGINE SPEEDS, DEPRESS THE "    " BUTTON  TO  REACH  DOUBLE  ZERO (00) ON THE DISPLAY BEFORE PROCEEDING. e. Depress    the    "RPM"     key     and     increase engine RPM to total pump timing speed, as specified      in      PERFORMANCE         DATA GUIDELINES, Section 6. f. With  the  ADVANCE  mode  reset  to  double zero (00), increase the ADVANCE mode (by one increment at a time) using the " " key until  the  TDC  mark  and  front  cover  pointer align.        When    marks    are    in    alignment, release  the  "    "  key.    The  injection  pump timing (Degrees of Advance) will appear on the  digital  display.    Compare  readings  with specifications. NOTE:  Do    not    exceed    specified    maximum    total pump timing speed (RPM). IMPORTANT IF THERE IS A QUESTION OF TIMING LIGHT  ACCURACY  FLOW  TIME  THE PUMP AS DESCRIBED IN SECTION 5. FLOW    TIMING    IS    ACCOMPLISHED WITH-   OUT   REMOVING   THE   PUMP DELIVERY VALVE. CGES-240-4 Printed in United States of America Page 10
