n extra set of hands are what’s needed to raise or lower the hood on your M-ATV.
That extra help prevents the stress cracks caused by Fexing and keeps the hood from
slamming shut.
Having a buddy on the other side also allows you to guide the hood past the bundle
of electrical connectors on the driver’s side. Otherwise, the hood might damage one
or more connectors. A damaged connector for the vehicle’s washer Fuid reservoir, for
example, means you can’t wash a dirty window. That’s a real bummer!
As an added precaution, use a tie strap, NSN 5975-00-156-3253, to secure the
connectors together to the cold start bracket and power steering line. That’ll keep all
of the connectors out of harm’s way.

here there’s smoke.
.. there may be ±re! Keep that in mind with the M-ATV’s
battery power cables.
Before the smoke and ±re hit your M-ATV, you need to get down on your hands
and knees and inspect the vehicle’s battery cables, especially behind the transfer case
area and hull.
Here’s what to look for:
Transfer Case Area
One recent ±re came from
a battery cable and hose
clamp that were pinched
against a steel plate in the
transfer case area, causing
an electrical short.
The short melted a steel
vent elbow, which released
and
ignited
fuel
vapors,
causing a ±re beyond the
reach of the vehicle’s ±re
suppression system (²SS).
That particular ±re melted
the engine’s fuel return line
and damaged all the air, fuel
and electrical lines in the
transfer case area forward of
the fuel tank. The ±re had to
be put out with a hand-held
±re extinguisher.
