a. Inspection. Inspect the entire wiring system for loose or dirty connections. Follow each lead and check for cut,
damaged, swollen, frayed, or chaffed insulation. Pay particular attention to the wiring around the starting motor and battery
generator; see that the insulation is dry and free from oil and grease drippings.
b. Repair. In emergencies, broken cables may be soldered, but the entire wiring cable from one terminal to another
must be replaced when the emergency is over. Broken or damaged insulation can be temporarily repaired in emergencies
by taping the damaged place with insulation tape. Replace the entire wiring cable when the emergency is over.
c. Cleaning. Clean the wiring cables with a soft cloth dipped in cleaning solvent. If the connections are rusted, dirty,
or covered with oil, remove the mounting screws and clean the terminals with a brush and cleaning solvent. Use a wire
brush and No. 00 sandpaper to remove dirt and rust from the terminals. Clean the terminals with No. 00 sandpaper until
clean, bare metal is visible. Inspect the threads and heads of the mounting screws. Clean them with a wire brush. See that
the screw head makes contact with the terminal and that they both are clean and tight. Tighten all connections and double-
check the entire wiring system for proper mounting and secure connections.
120. Instrument Panel
a. Description. The instrument panel consists of the instrument panel bracket (13) and the cluster gage assembly
(14). The instrument panel bracket (13) is welded to the housing of the compression roll. The cluster gage (14) is attached
to the instrument panel bracket (13) by two mounting clamps (5) and nuts (6).
b. Cluster Gage Removal.
(1) Disconnect the battery ground cable from the battery terminal to prevent accidental arcing. Refer to
(2) Remove the oil gage terminal nut (4) and disconnect the starter button lead (2) and the oil gage lead (3)
from the oil gage terminals. Tag the leads.
(3) Remove the fuel gage terminal nut (8) and disconnect the fuel gage lead (7) from the fuel gage terminal.
Tag the lead to facilitate-installation.
(4) Remove the temperature gage terminal nut (15) and disconnect the temperature gage lead (16) from the
terminal. Tag the lead.
(5) Remove the ammeter terminal nuts (21) and disconnect the ammeter leads from the terminals. Tag the
