Boyce dials 79 into
the TEST SELECT switches.
He then presses and releases the TEST
button. Since the message word GO appeared on the display, SSG Boyce
turns the rotary switch to the START position until the message word
OFF appears on the display.
SSG Boyce waits for the display to
A number should be displayed; however, the display
changes to E013.
This error message indicates that the battery or
batteries need to be-charged. Once they have been charged, the test
procedures are repeated. If E013 is displayed again, this indicates
that the battery or batteries need to be replaced.
They should be
replaced following the procedures in paragraph 4-56, page 4-92 of the
Had this not been the case, SSG Boyce would have proceeded to the
next step in the test procedures and measured the battery resistance.
For an M998, like the fictitious one we have been testing, the
battery resistance should be 13 milliohms.
After completing the necessary repairs, SSG Boyce reruns the Go Chain
tests to verify that the malfunction has been corrected and that no
additional malfunctions exist.
In this task, we covered STE/ICE. We covered what it is and how it
operates. We also covered how to use this piece of test equipment to
troubleshoot malfunctions occurring in the HMMWV.
