PAGE 36 — AR13D RIDE-ON TANDEM DRUM ROLLER — OPERATION & PARTS MANUAL — REV. #2 (09/15/11)
Alternator/Regulator
The AR13D is equipped with a 40 amp charging system. This
system uses three charge coils connected in parallel. The
windings of each coil are wound with heave-duty insulated wire
and are further protected by insulating material for long life. A
voltage regulator is provided to control the amount of charge
voltage being delivered to the 12 volt electrical system. For
servicing this charging system, contact your engine dealer.
Neutral Safety Switch
The
travel lever
is provided with a
neutral
safety switch
(Figure 40) that prevents the engine from starting when the
lever is in the forward or reverse drive position. Lever must
be placed in the neutral position in order for the starter to
function.
To check this switch, remove the panel located below and to the
rear of the floor. This switch is mounted to the lower forward/
reverse lever mechanism. Disconnect the
white
and
green
wires.
Place the lever in neutral and test for continuity. Place the lever
in forward or reverse; no continuity should be present. Repair or
replace as required.

Vibrator Solenoid
The vibrator solenoid (Figure 41) is located in the manifold valve
block and is controlled by the vibration switch located on top of
the travel lever. This solenoid controls the vibration control valve
which supplies hydraulic oil to the vibration drive motor.
To test the vibration solenoid, turn the ignition switch on. Check
for proper supply voltage and ground. If proper voltage and
ground are present, check the solenoid for continuity. If no
continuity, replace the solenoid coil. If continuity is present, place
your hand on the solenoid and turn the switch to the ON position;
movement should be felt. DO NOT START THE ENGINE FOR
THIS TEST

Battery
Mishandling of the battery shortens the service life of the battery
ans adds to maintenance cost. When handling the battery do the
following:
Be careful not to let the battery electrolyte come in
contact with your body or clothing.
Always wear eye protection and rubber gloves, since
the battery contains sulfuric acid which burns skin and
eats through clothing.
If your clothing or skin comes in contact with the battery acid,
immediately
wash off with running water and get medical
attention.
Check the battery regulary and make sure that each
electrolyte level is to the bottom of the vent well
(Figure 42). If necessary add only distilled water in a
well-ventilated area.
