4. OPERATION
4.1.
CONNECTING BOOSTER CABLES
4.1.1.
Starting with the clamps at the end nearest to the surge protector, attach the red (positive) clamp to the positive terminal of the
charged battery.
4.1.2.
Connecting the second red (positive) clamp to the positive battery terminal of the vehicle’s flat battery.
4.1.3. Connect Black (negative) clamp at the end nearest to the surge protector, to the negative terminal of the charged battery.
4.1.4.
Finally connect the black (negative) clamp to an unpainted part of the chassis or engine on the vehicle with the flat battery.
WARNING!
Ensure that the connection point is not near the battery, carburettor, fuel or brake pipes to minimize any fire risk that
could be caused by sparking.
4.2.
STARTING THE VEHICLE
4.2.1.
Ensure that all leads are clear of all moving or hot parts
4.2.2.
Start engine of vehicle with charged battery and let run for a minute
4.2.3.
Try to start the vehicle with the flat battery if it starts run for one minute then remove the cables.
4.2.4.
If the cables become hot switch off both vehicles and allow to cool down before attempting to restart the vehicle.
4.3.
DISCONNECTING THE BOOSTER CABLES
4.3.1.
Turn off the engine with the charged battery
4.3.2.
Then remove the cables in reverse order to that described in 4.1
WARNING!
Take care to keep clear of all moving or hot parts.
4.4.
BATTERY CONDITION INDICATOR
4.4.1.
The Voltage indicator displays the voltage when the vehicle engine is not running.
4.4.2.
A reading of 10.5Volts on a 12V battery or 22Volts on a 24V battery - indicates battery very low in charge may be damaged and not
be able to start vehicle.
4.4.3.
A reading of 11.5Volts on a 12V battery or 23.5Volts on a 24V battery - indicates the battery needs charging or may be damaged.
4.4.4.
A reading of 12.3Volts on a 12V battery or 24.3Volts on a 24V battery - indicates that the battery is fully charged and in good
condition.
4.5.
TESTING THE BATTERY CONDITION
4.5.1.
Insulate the positive and negative clamps nearest the voltage display by clamping to a non conductive material.
4.5.2.
Connect the other positive clamp to the positive terminal of the vehicle battery, then connect the negative clamp to the negative
terminal of the battery.
4.5.3.
When the booster cables are connected the voltage will be displayed on the LED indicator.
4.5.4.
Having confirmed the battery condition remove the cables in reverse order.
4.6.
ALTERNATOR CHARGING CHECK
4.6.1.
The alternator function can be checked to see if it is charging the battery at the correct rate. Connect the clamps as described in
4.5 above.
4.6.2.
Start the engine and monitor the voltage on the LED indicator.
4.6.3. In most cases the alternator will be functioning correctly if the display indicates 13.7-14+ Volts on a12V battery or 24.7-25+Volts
on a 24V battery. Check manufacturer’s specifications for recharge voltages as charging above 14Volts for 12V battery and above
25Volts for 24V battery indicates a possible fault in the alternator this should be checked by an auto electrician.
4.6.4.
Remove clamps in reverse order.
4.7.
REVERSE POLARITY LED INDICATOR
4.7.1.
The LED indicator illuminates red and omits an audible tone when the booster cables are incorrectly connected to the charged
battery if this happens reverse the leads. If the LED is not illuminated and there is no audible tone continue to connect leads as
described above.
5. TROUBLESHOOTING
Problem
Causes
Solutions
Flat Battery vehicle will not turn over
I
nsufficient/bad booster cable clamp
connection
1. Reconnect the booster cables as in
instructions.
2. Check the battery terminals are
corrosion free if not clean and reconnect.
Booster cables connected incorrectly
Check if the reverse polarity LED is
illuminated (red) and an audible tone can
be heard. If so disconnect clamps and refit
as instructions.
Booster Cable gets hot
Incorrect booster cables being used
Check the the vehicles battery AMP rating.
Change the cables to the correct AMP type
if incorrect
The vehicle’s management system may not
be working correctly and may be stopping
the vehicle from starting. Excessive
cranking of the engineer may cause cables
to get hot.
Stop trying to jump start the vehicle and
consult automotive electrician.
