AGE
The age of a golf car has little to do with its value. Unlike your car,
a well maintained 10 year
old golf car can have as much or more value as a poorly maintained 5
year old golf car. The
condition of the body, frame, top, batteries, and charger are the key
areas of concern when
determining the value of a trade-in.
AIR
To fully understand clean air's impact on an engine, consider this: Engines
running at full
speed consume, on average, 10,000 gallons of air for every gallon of
gasoline.
The
air cleaner element shoulders the huge responsibility
of making clean air. Unfortunately, it is also
an engine's most neglected part. Too often,
engines deemed as not running right are magically
fixed when the air cleaner is removed and cleaned,
or replaced.
Air
cleaners are designed to filter air. Accordingly,
they will eventually become clogged and
will need replacement.
Unfortunately,
end-users of off-road recreational vehicles
do not regularly replace the air
cleaner. This severely compromises the engine's life.
BATTERY
OPERATION AND CARE
Charging: Correct charging methods extend battery life
and range between charges.
Charge
new batteries completely before they are used
the first time. Charging time will
probably be at least 12 hours. New batteries need up to four hours more
charging time than
"mature" batteries.
Schedule
enough charging time, if possible, so the charger
shuts off automatically. Age of
battery, condition of battery, state-of-discharge, temperature of electrolyte,
AC line voltage
level, and other variables affect charging time.
Limit
the use of new batteries between charging for
the first 5-20 cycles. New batteries have
less capacity than batteries which have been broken in. New golf car
batteries should be
limited to 18 holes between charges. Industrial vehicle batteries should
not be discharged
more than 20-30% before recharging.
Whenever
possible, for longest battery life, recharge
batteries as soon as they become 20%
discharged (1.233 SG/37.38 volts). Never allow batteries to fall below
80% discharged
(1.148 SG/35.94 volts). Deep discharging significantly reduces battery
life.
Batteries
in storage self-discharge and should be recharged
whenever the specific gravity
falls below 1.240. The rate of self-discharge varies directly with temperature.
Battery
state-of-charge can be determined by using
a hydrometer, or by connecting the
charger and observing the charging rate. If the ammeter needle jumps
smartly to 20-25
amps and then tapers below 14 amps within 15 minutes, the battery is
fully charged.
Watering: Correct watering techniques extend battery life.
Check
the electrolyte level on new batteries before
putting them into service, and at least
monthly on batteries in service. Water use increases as batteries age.
Never
allow the electrolyte level to fall below the
top of the plates. If the plates are exposed,
add only enough water to cover the plates before charging.
Do
not overfill batteries. Electrolyte expands
and can overflow during charging. Water added
to replace the spillage dilutes the electrolyte and reduces its specific
gravity. Cells with lower
specific gravity have lower charging capacity. Make sure the electrolyte
covers the plates
before charging and fill cells to the markers only after batteries are
charged.
Use
only distilled water. Electric vehicle batteries
may use up to 16 quarts of water during
their useful lives and non-distilled water may contain harmful minerals
which will have a
cumulative adverse effect on battery performance.
Cleaning: Acid-soaked
dirt on the battery tops causes current leakage
and reduced battery
efficiency.
Hose
wash battery tops periodically with clean low-pressure
water to keep them free of acid
spillage, dirt, grass cuttings and other debris. Make sure vent caps
are secure before
washing. Do NOT hose wash electronic controllers, switches, solenoid
and other electrical
control devices. Cover them if necessary.
Wash
the tops with a baking soda mixture (1/2 cup
per quart of water) and a stiff bristle
brush if a low-pressure hose doesn't remove the dirt. Rinse with clean
water.
Make
sure the battery tops are clean and dry before
putting them into storage.

Maintenance
BRAKES
Golf cars have brakes only in the rear. They are mechanical in nature,
like the parking brakes
on your automobile. There are no hydraulics or need for brake fluid.
Periodic adjustment and
brake shoe replacement is required at intervals, depending on usage.
COOLING
Properly cooled air is as important to an engine's life as oil. Air-cooled
engines are just that,
cooled by air. Air is drawn through the flywheel fins and forced over
a series of cooling fins,
expelling the heated air created during combustion. This process ensures
a constant supply
of fresh air rushing over the cooling fins. From a maintenance standpoint,
all that's really
needed is an occasional check to make sure nothing is blocking airflow.
Depending on the
application, blockage could occur from dust, grass, leaves, etc.
ELECTRIC
OR GAS
Electric golf cars and utility vehicles have made tremendous advances
in the last decade.
With less than 50 moving parts, very little can go wrong with an electric
car. Gas cars, on the
other hand, have over 1,000 moving parts. In Florida, gas golf cars are
rarely used, resulting
in very few for the resale market. The noise, smell and exhaust fumes
are disliked and add
to the lack of popularity. In addition, electric golf cars now have the
capability to go in excess
of 45 miles between charges.
GASOLINE
Oxidation can turn today's gasoline "stale" if left for prolonged
periods. "Stale" gasoline
leaves gummy deposits in the carburetor and valve train. When this occurs,
disassembly,
cleaning or replacement of affected part is generally required.
Gasoline
stabilizers do an excellent job of retarding
the oxidation process, and ensuring the
"burn ability" of the gasoline. Mineral-based fuel additives offer
outstanding protection for
gasoline both in storage and in use.
HORSEPOWER
AND SPEED
Components of the internal combustion engines vary greatly based upon
the manufacturer.
Electric motors for golf cars, however, are very similar, regardless
of brand. Power and
speed is regulated by the amount of current in amps that goes to the
motor and the gear
ratios of the drive train. Unlike your automobile, there is no transmission
or clutches. A 2-3
horsepower motor can easily move a 5,000 pound trailer. For safety, golf
cars are limited to
a speed of 12-18 mph regardless of horsepower.
OIL
Engine oil has been considered the lifeblood of any engine. In addition
to its lubrication
responsibilities, oil has equally important responsibilities to cool,
seal, and clean.
In most of today's engines, special properties in oil are needed to meet
the demands of
today's applications and engine technology. Long gone are the days of
non-detergent oil.
Operating temperatures and load demands placed on today's engines make
detergent oils
a necessity. The need of adequate amounts of oil are easy to understand
and simply stated:
More oil means cooler oil. This is not to say that engines should be
overfilled; it is to say they
be kept clean and full. Oil dissipates heat build-up through the crankcase.
The less oil
present, the less dissipation, thereby increasing the engine's operating
temperature. Too
little oil in an engine will melt metal. Obviously, this is the beginning
of the end for your
engine. When it comes to oil, pro-active strategies clearly beat re-active
strategies.
TUNE-UPS
There is no need for tune-ups on electric golf cars, since there are
few moving parts.
Lubrication of a few key areas and brake adjustments are the only requirements.
