INTRODUCTION
The Battery Isolator XR is a fully electronic ‘master/kill switch’ system designed specifically for race
car applications. This device contains no moving parts and the solid construction provides very high resistance
to shock, vibration, water and dirt. Using the latest MOSFET technology this Battery Isolator provides safe,
spark-free isolation of the vehicle’s battery and engine electrics.
Meets FiA safety regulations.
PRINCIPLE OF OPERATION
All race and rally master switches must perform two functions, (1) disconnect the battery from all electrical
circuits and (2) kill the engine. The Battery Isolator XR performs the battery disconnection function by breaking
the connection between the NEGATIVE battery terminal and CHASSIS/EARTH. The Battery Isolator XR performs
the engine kill function by outputting a signal which can be used to enable/disable ECUs or PDMs or used to
control an engine relay.
Alternator run-down protection is incorporated.
The electronic isolation circuits are controlled by a microprocessor and incorporate various safety systems
including over-temperature and over-current monitoring. The microprocessor also monitors the kill
switches/buttons for instant activation while eliminating false triggering. The unit will therefore instantly
trigger into isolation mode when any of the kill buttons are struck or on detection of any break in switch wiring
circuits such as during an accident.
The Isolator also incorporates an LED which displays status as well as fault codes.
Battery Isolators are designed for SAFETY and RELIABILITY.

SAFETY NOTES
●Please read through the Instructions thoroughly before installing on your race car. If not installed correctly
then damage may occur to the Battery Isolator.
●The Battery Isolator must be fully connected before starting the engine. If the engine kill output signal is
not connected when the engine is running then damage to the Battery Isolator may occur. (Cars without
alternators do not apply).
●Do not use the Internal Button for any other application, it is designed specifically for use with
Battery Isolators only.
●The Battery Isolator must be removed if any electric welding is being carried out on the car.
●When using a Battery Charger or an external starter/booster battery then it is important to connect both
terminals directly to the car battery. DO NOT CONNECT THE NEGATIVE LEAD OF THE CHARGER OR
EXTERNAL BATTERY TO THE CHASSIS. THIS MAY CAUSE DAMAGE TO THE BATTERY ISOLATOR.
MOTORSPORT IS DANGEROUS.
THIS PRODUCT IS DESIGNED FOR MOTORSPORT USE ONLY AND SHOULD NOT
BE USED ON ROAD/STREET VEHICLES OR ON PUBLIC HIGHWAYS.
NO WARRANTY IS MADE OR IMPLIED REGARDING ANY CARTEK PRODUCTS TO
PROTECT USERS FROM INJURY OR DEATH.
USER ASSUMES ALL RISKS.

INSTALLATION
Step 2. FITTING
The Battery Isolator should be mounted directly to the vehicle’s metal chassis close to the vehicle’s battery
but away from any high temperature sources.
The Battery Isolator should be mounted securely with unpainted screws/bolts to provide good electrical
contact with the chassis.
If mounting directly to a metal chassis is not possible then an 'earth' cable can be used to connect the
metal casing of the Battery Isolator to a suitable point on the chassis or engine block.

INSTALLATION
Step 2. SWITCH CONNECTIONS
The Isolator can be controlled by any number of on-off/kill switches although the usual configuration is one
internal on-off button and one external kill button.
The internal switch needs to be of a latching type, either toggle or pushbutton, such that the ON position
makes the circuit while the OFF position breaks the circuit.
The external kill switch should be of the non-latching, momentary action, normally-closed (NC) type and
connected between the Blue wire and chassis earth. If required, multiple kill switches/devices can be
incorporated by connecting in series. If only a single internal on-off switch is to be used with no external
switch then the external circuit needs to be complete by connecting the blue wire to earth. If any wire
connection becomes broken due to fatigue or accident then the Battery Isolator will automatically switch
OFF killing the engine and disconnecting the battery.
WARNING: Do not test the Internal Button by passing power through it, this will damage it. It will only
work correctly when connected to the Battery Isolator.

INSTALLATION
Step 3. ENGINE KILL CONNECTION
For cars equipped with an alternator, the Battery Isolator needs to kill the engine by sending a signal to the
engine ECU or electronic Power Distribution Module (PDM) or by shutting down the main engine relay.
The engine kill output signal has two states:
Battery Isolator ON - 12V (0.5A max).
Battery Isolator OFF - 0V(Earth).
Make sure the ECU or PDM is able to accept this type of Engine Kill Signal. Most OEM ECUs will not be able
to accept this type of signal while most programmable Motorsport ECUs and PDMs will.

WARNING: The Battery Isolator must be fully connected before starting the engine. If the engine kill
output signal is not connected when the engine is running then damage to the Battery Isolator may
occur. (Cars without alternators do not apply).
INSTALLATION
Step 4. FINAL CONNECTION
Once Steps 1,2 & 3 are completed a final connection should be made from the negative terminal of the
vehicle battery to the Battery Isolator terminal marked BATTERY NEGATIVE. This connection should be made
with cable of 100-200Amp capacity and by keeping as short as possible will offer maximum weight saving of
the complete installation.
Once this final step is complete please check all connections before switching on.
When fitting or removing the Isolator always connect the battery last and disconnect first.
