MAGNETIC PROBE METHOD -CRANKSHAFT
MONITORING 6.9 LITER DIESEL ONLY
1.
Insert the magnetic probe into the magnetic pick-
up access hole located on engine. (See Figure
9).
2.
Plug probe terminal into the receptacle on the
SE-4142 body labeled "MAGNETIC PICK-UP".
3.
Set toggle switch to "MAGNETIC PICK-UP"
position.
4.
Connect the SE-4142 battery leads to the vehicle
battery (red to "+", black to "-"). Display should
light up and read (Set ...... 20.0).
CAUTION!
Do not connect to battery system
with a "floating ground". The SE-
4142 should be powered from a
source with a "fixed ground".
5.
Set timing offset degrees to 20° for 6.9 Liter "S"
Series applications. To set, hold "OFF-SET
ADJUSTMENT" rocker switch down while
simultaneously depressing either "INCREASE"
or
"DECREASE"
on
the
rocker
switch
immediately above it, until you reach the 200
offset angle. Release both switches. Display
should now read all zeros.
6.
Make sure all cables and wires are clear of fan,
belts or any other moving parts. Keep wires
away from exhaust manifolds.
7.
Start engine. Sensor light on SE-4142 should be
blinking regularly, indicating proper function of
connectors. Allow engine to reach operating
temperature.
8.
Check initial dynamic timing and advance by
adjusting engine RPM and actuating housing
pressure solenoid as directed in Section 5.
9.
Engine RPM and timing angle can be read
directly from the SE-4142 display.
10.
Repaint the scraped fuel line when timing
operation is complete to protect the line against
corrosion.
