REFERENCE INFORMATION
The electrical coil power circuits for the tow point
cylinders receive their ground through the tow
point movement switch. The circuits have a +12
vdc applied whenever the ignition switch is on.
The electrical coil ground circuit is completed
only when a tow point movement switch is
placed in the up or down position.
Refer to paragraph 1.21.4 for an electrical
control system description for the tow point
cylinders.
Open center top right and center top left access
doors per TM 5-3895-373-10 to gain access to
tow point control valves.
To avoid reversing polarity to the voltmeter,
connect negative test lead to equipment ground
and use positive lead to probe for voltage.
Refer to the electrical system diagram at the end
of the manual for equipment wiring details.
After completing diagnostic checks, close center
top left and center top right access doors per TM
5-3895-373-10.
