Equipment Condition
Master switch off
Battery ground cables disconnected (TM 9-2350-256-20)
WARNING
Certain precautions must be observed when removing electrical components. Accidental contact of
metal tools between battery or starter cables and the frame of the vehicle causes a direct short circuit
resulting in arcing and instant heating of the tool to red hot. This can cause painful burns on the hands
and serious damage to tools, vehicle components and batteries. Moreover the overloaded battery may
explode, spraying hot acid and sharp fragments over the surrounding area. The correct procedure when
removing electrical equipment, harnesses, leads, or cables is to first turn off the master switch and then
disconnect the battery ground cables. Protect the ground cables from accidental contact with the battery
terminals. When the work has been completed, connect the battery ground cables last.
CAUTION
When removing harnesses, leads, and cables, check circuitnumbermarkers. If any are missing, illegible,
or damaged to the extent that they might come off, tag cables with correct circuit numbers (refer to the
vehicle wiring diagram in TM 9-2350-256-20) prior to disconnecting them.
Removal
1.
Refer to WPs 0034 00 thru 0038 00 and TM9-2350-256-20 for removal instructions of wiring harnesses. The circuitnumber
of each cable is shown on a metal band attached to the junction of terminal end of each cable. Refer to TM 9-2350-256-20
for a listing of the circuit numbers assigned to the vehicle and for the vehicle wiring diagram.
Disassembly
1.
Unwrap or cut tape which binds the wires or cables to the old harness.
