Cartek GT Battery Isolator – Red Button

The Cartek GT Battery Isolator is a compact, fully electronic battery isolation system designed to improve electrical reliability, enhance safety and reduce weight in motorsport vehicles. With no mechanical moving parts and a sealed construction, it is built to withstand the demanding conditions of competition use.

Weighing just 120g, the GT combines battery isolation with an integrated alternator run-down function and a protected 12V engine-kill output. The system can be operated from an internal ON/OFF switch or external strike buttons, providing convenient control for the driver and an external shutdown point.

The GT is designed for vehicles without an ECU or with a standard original-equipment ECU. Check compatibility with your vehicle's electrical and engine management system before installation, particularly if it uses an aftermarket ECU or modified electrical architecture.

This version is supplied with a red button.

Specifications

How the Cartek GT Battery Isolator Works

The GT isolates the battery by disconnecting its negative connection from the chassis. It also provides a switched 12V output for a compatible ignition or engine management power circuit.

When the isolator is switched off, the battery negative is disconnected and the switched output is cut. This allows the engine to be stopped through the designated ignition or ECU power circuit, provided the vehicle's wiring is configured correctly.

The integrated alternator run-down function is part of the unit's design. Correct installation is essential to ensure the isolator operates as intended and does not compromise the vehicle's electrical system.

Installation and Compatibility

The Cartek GT should be installed by someone competent in motorsport vehicle electrical systems, following the manufacturer's wiring diagram and instructions.

Before installation:

• Confirm the vehicle's operating voltage and electrical architecture are compatible.
• Check that the ignition or ECU circuit can be controlled using the isolator's protected 12V output.
• Confirm the suitability of the unit for the vehicle's alternator and engine management system.
• Position and wire any external strike buttons in accordance with the applicable motorsport regulations.
• Verify the complete isolation and engine-stop functions before the vehicle is used in competition.

Important: The GT is specified for vehicles without an ECU or with a standard original-equipment ECU. Do not assume it is suitable for aftermarket ECU installations or every modern vehicle without confirmation from Cartek.
