6. After making contact with the ywheel gear tooth,
unscrew the MPU sensor counterclockwise 1/2 turn.
Reference Figure 79.

7. Verify that the MPU sensor does not make contact with
the ywheel by rotating the ywheel gear completely
around. Flywheel should rotate freely.
8. The MPU sensor-ywheel gear gap should be adjusted
so that the minimum voltage required is attained while
the engine is in crank status. The voltage setting we
are looking to obtain is 2.25 VAC +/- 0.50 VAC.
9. Once the correct gap is obtained, tighten the MPU
sensor jam nut to secure it to the sensor plate.

FUEL FEED PUMP STRAINER
The fuel pump strainer is used on all DCA generators
equipped with Isuzu engines.
The fuel feed pump strainer is located inside the banjo bolt
which is attached to the fuel-water separator as shown
in Figure 80. Inspecting and cleaning the fuel strainer is
considered part of regular maintenance. If the strainer
becomes clogged, remove it from the banjo bolt and clean
it with clean, fresh diesel fuel. If the fuel strainer cannot be
cleaned, replace it.
Examples of a clogged strainer are:
Hard starting
Engine runs rough
White smoke emitting from exhaust
