Page 10
OPERATIONS AND CONTROLS (Continued)
(A) BATTERY STATE OF CHARGE
METER
The battery state of charge meter on the
left side of the console is an analog
gauge with an indicating needle and a
colored background. It is a continuously
reading meter. At rest with fully charged
batteries the meter should read in the
right white region.
When accelerating quickly, the needle will
move to the left green region near the
very far left red region. This is normal. If
the needle continues past the green
region into the very far left red region, it
indicates that the batteries need
recharging as soon as possible to avoid a
shut-down of the vehicle.
(B) SYSTEM STATUS LIGHT
If equipped, the green system status LED
will light when the power keyswitch is
turned to the “ON” position. This indicates
the controller is powered up and should
display a steady green light.
With the power keyswitch “ON”, if this
green status light is not lit or is flashing
refer to the controller troubleshooting
section later in this manual.
(C) HOUR METER INDICATOR
If equipped, the hour meter indicates the
total number of hours the vehicle has been
operating.
(D) LIGHT SWITCH
If equipped, the light switch is a two-position
switch. Move switch up to activate headlights
and taillights, down to turn off.
(E) DIRECTION SELECTOR
When the direction selector is in the vertical
position, the vehicle’s direction signal is
turned OFF or in neutral (N).
Turn direction selector to the right from
vertical position to move the vehicle in
forward (F) direction. Turn direction selector
to the left from vertical position to move the
vehicle in reverse (R) direction. A warning
buzzer sounds when in reverse.
NOTICE: Vehicle must be stopped before
changing direction selector or damage to
controller or motor could occur.

Stockchaser IS12
Page 11
ACCELERATOR AND BRAKE PEDAL
The accelerator/brake pedal moves the vehicle when the toe portion of the pedal is depressed.
When the pedal is in the upright position, the spring applied brake system is engaged.
With the direction selector in the desired direction of travel, depress the pedal slowly until the
appropriate speed is reached.
Reducing pressure on the pedal slows the vehicle. Release the accelerator/brake pedal slowly
and completely to stop the vehicle. Rapid release of the pedal will stop the vehicle abruptly.
To avoid injury, speed in reverse should always be kept at a minimum.
Be sure the direction selector is in the desired direction of travel before depressing the
accelerator pedal.
This vehicle is equipped with a dual braking system.
When the accelerator pedal is in the raised position, the service spring applied
mechanical brake system will activate the brake shoes on the axle assembly. This
function operates regardless of power application.
When power is applied, the vehicle controller will also function in the regenerative
braking mode. This function operates when the accelerator is in the raised position
and the unit is travelling forward or reverse. This function does NOT operate with
power turned off.
In the event of a runaway condition, leave power applied and lift left foot from
accelerator pedal.

ELECTRICAL SYSTEM
The type of battery used in a Columbia vehicle has a service requirement which is quite different
from that of an automotive battery.
The electric vehicle battery supplies all of the power to drive the vehicle. During operation the
power stored in the batteries is expended. While the amperage drain rate can vary greatly
depending on the type of service, the duration of use and the number of "starts" and "stops"
made during a day, the batteries nevertheless progress through each duty cycle from "fully
charged" to an almost depleted state. This type of service is known as "deep cycle" service and
electric vehicle batteries are specifically designed to handle this type of service.
Proper performance of your Columbia Vehicle can only be obtained from specified deep cycle,
electric vehicle batteries.
PLEASE REVIEW IMPORTANT DANGER STATEMENTS WHEN WORKING NEAR
BATTERIES AND CHARGING SYSTEMS!
Battery acid is poisonous and can cause severe burns. Avoid contact with skin, eyes,
or clothing.
ANTIDOTES:
EXTERNAL: Flush with water. Call a physician immediately.
INTERNAL: Drink large quantities of milk or water. Follow with milk of magnesia or
vegetable oil. Call a physician immediately.
EYES: Flush with water for fifteen minutes. Call physician immediately.
Always remove key and disconnect battery pack before servicing or repairing the
vehicle. See BATTERY DISCONNECT METHOD.
Always wear full-face shield when working on or near batteries.
All batteries used in electric vehicles can explode! Batteries produce explosive
hydrogen gas at all times, especially, during charging or discharging. Ventilate area
when charging batteries.
Do not attempt to charge a battery if it is frozen, or if the case is bulged excessively.
Frozen batteries can explode! Properly dispose of the battery.
Do not smoke around batteries. Keep sparks and flames away from batteries and the
charging area. Use care to prevent an accidental arc which could cause an explosion.
Use only approved insulated tools, remove jewelry such as rings, watches, chains etc.
and place an insulating material (wood, plastic, rubber etc.) over all battery
connections.
Never add acid to a battery.

Stockchaser IS12
Page 15
To reduce the risk of electrical shock or injury:
Do not use an ungrounded two to three-prong adapter to connect the charger to a two-
prong outlet or extension cord.
The battery charger must be properly grounded. Use a three prong No. 12 AWG heavy
duty power cord no more than 50 feet long.
Locate all cords so that they will not be stepped on, tripped on, or otherwise damaged.
Immediately replace worn, cut, or damaged power cords or wires.
Do not connect the power cord near fuels, grain dust, solvents, thinners, or other
flammables. The spark can ignite flammable materials and vapors
NOTICE: Automotive batteries should never be used for "deep cycle" application, as
their useful life will be very short.
Damaged or corroded battery terminals should be replaced or cleaned as necessary.
Failure to do so may cause overheating during operation. Torque connections to 100
in. lbs.
Do not attempt to recharge batteries with a charger not designed for your vehicle.
Only trained technicians should service the charger. Contact your Columbia Dealer for
assistance.
NOTICE: Install surge arrestors on incoming AC power lines. Surge arrestors will help
protect electrical/electronic components in the charger and vehicle from all but direct
or “close proximity” lightning strikes.
BATTERY INSPECTION & MAINTENANCE
1. Be sure battery hold downs are properly tightened. A loose hold down may allow the battery
to become damaged from vibration or jarring. A hold down that is too tight may buckle or
crack the battery case.
2. Weekly inspect battery posts, clamps and cables for breakage, loose connections and
corrosion. Replace any that are damaged. Batteries and connections must be clean and dry.
Torque connections to 100 in. lbs.
3. Weekly an equalization charge is to be applied to the battery pack. This process balances
the electrical charge in the battery pack and will extend battery life. The following procedure
is used to complete this.
 Charge the battery pack allowing the charger to go to green 100% charge.
 Once the green LED lights unplug the power cord.
 Wait approximately 30 seconds. Reconnect the power cord and allow the charger to
complete a second charge cycle.
 If the vehicle is not to be used, leave power cord connected. The on-board charger can test
and recharge as needed.

NOTICE: Automotive batteries should never be used for "deep cycle" application, as their
useful life will be very short.
Install surge arrestors on incoming AC power lines. Surge arrestors will help protect
electrical/electronic components in the charger and vehicle from all but direct or “close

Damaged or corroded battery terminals should be replaced or cleaned as necessary. Failure to
do so may cause overheating during operation.
Do not attempt to recharge batteries with a charger not designed for your vehicle.
Only trained technicians should service the IS-12 charger. Contact your Columbia Dealer for
assistance.
BATTERY CLEANING
Acid-soaked debris on the battery terminal connections will cause current leakage, reduces
battery efficiency, and battery life.
Hose wash battery terminal connections periodically with clean low-pressure water to keep them
free of acid spillage, dirt, and other debris. Do not hose wash electronic controllers, switches,
solenoids and other electrical control devices. Cover as necessary to prevent splashing. Clean
battery terminal connections with baking soda (sodium bicarbonate) and water solution. Mix 5
teaspoons baking soda per quart of water. Use a stiff bristle brush, rinse with clean water and
dry with a clean cloth. Torque connections to 100 in. lbs
NOTICE: The following information does NOT apply to sealed batteries.
1. Check the electrolyte level on new batteries before they are put into service, and, at a
minimum, once a week thereafter. Water use increases as batteries age. If the vehicle is
equipped with a Single Point Battery Watering System see the information on this in this
section.
2. Never allow the electrolyte level (A) to fall below the top of the plates (C). If the plates are
exposed, add only enough to cover the plates before charging.
3. After batteries are fully charged, fill cells to just below the bottom of the cell vents (B),
approximately 1/8” to 1/4”. Electrolyte level should not touch the bottom of the cell vents.
4. 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.

Stockchaser IS12
Page 17
BATTERY CLEANING (Continued)
5. Use only distilled water. Vehicle batteries may use up to 16 quarts of water during their
useful life and non-distilled water may contain harmful minerals which will have a cumulative
adverse effect on battery performance and life.
6. Check to see that battery cap vent holes are clear. Plugged vent holes will not permit gas to
escape from the cell and could result in battery damage. Check that all vent caps are tightly
in place. Do not allow water or cleaning solution to enter cap vent holes.
NOTICE: Follow local ordinances and codes for proper disposal of battery cleaning
waste.
CONDITIONS WHICH AFFECT CHARGING
Always schedule enough charging time so the charger attains the 100% level. Charging time is
affected by age and battery condition, state of discharge, electrolyte temperature, AC line
voltage, and other variables. Correct charging methods extend battery life and vehicle range
between charges. If vehicle is used only occasionally, a refresher charge should be given prior
to using.
New batteries need up to four hours more charging than “mature” batteries. Before the first use,
completely charge new batteries. Charging time will vary based on conditions noted above but
will probably be 12 hours.
Limit new batteries use between charges for the first 25 – 50 cycles. New batteries have less
capacity than seasoned batteries. New batteries should not be discharged more the 20 – 30%
before recharging. This will prevent premature battery failure.
Battery efficiency is affected by temperature. If the temperature of the outside air and/or
batteries is below 60º F, battery capacity is reduced. Batteries will require more frequent and
longer charge periods in early spring, fall and winter.
As batteries age, they finish charge at progressively higher charge rates and tend to use more
distilled water. At this point in battery age, charger will automatically begin reducing charge time.
Batteries found defective must be replaced. All batteries in a vehicle should be matched
according to age, capacity and brand.

BATTERY CHARGING
Connect the supplied power cord to the vehicle charger receptacle and to a
properly grounded 120 volt AC supply minimum 20 amp circuit wall outlet.
Charger start and charge time is automatic. The receptacle is located directly
beneath the key switch on the right side of the console.
Charger start and charge time is automatic. The remote LED will be flashing
short green. If this LED is not lit check the AC connection and the AC source
fuse or breaker. If this fails to correct the problem, contact your Columbia
Dealer for assistance.
Charger will automatically turn on and conduct a short self-test and battery
pack test. The LED will flash in sequence and then a trickle current will be
applied to batteries until a minimum voltage is reached.
If the batteries meet the minimum voltage requirements of the charger, signifying they are
serviceable (chargeable), the charger enters the bulk charging (higher amperage-constant
current) stage. The remote LED will be flashing short green.
NOTICE: If the batteries are excessively discharged, the charger will not be able to
charge the complete set of batteries. The remote LED will be flashing red (see Red
Light Charger Error Codes). It will then be necessary to follow the Special Charging for
Excessively Discharged Batteries.
When the charger has completed approximately 80% state of charge the remote LED will flash
long green as the last 20% of charge is returned to the batteries in the second phase (constant
voltage phase).
NOTICE: You can terminate charging at this point if necessary. The vehicle can be
used, but completing the charge cycle is highly recommended.
A Green LED continuously lit indicates the batteries are completely charged. The charger may
now be unplugged from the AC source. If the batteries will not be used for a length of time,
check monthly for the charge level. It is also acceptable to leave the charger plugged in. The
charger has the capability to test and recharge if necessary.
Repeated “Short Charging”, leaving the charge short of 100% will shorten operating cycle
distance and reduce battery life.
A fault occurring while charging causes the remote LED to flash with a code relaying the error.
Some errors may require repair by a qualified technician and others may be simply transient
and will automatically recover when the fault condition is eliminated and the charger cycled by
disconnecting the AC source for a minimum of 11 seconds.
NOTICE: A Yellow (Amber) flashing remote LED indicates the thermostatic control has
limited the charger output due to ambient temperature conditions. It is still charging,
but at a reduced rate.
