However, our system also allows multiple kill switches to be installed and the fitment of two external ‘kill’ buttons, one on each side of a race car, has become popular safety feature.Īll switches/push- buttons are connected to the Isolator via light weight, low current wiring and configured such that the Battery Isolator will automatically turn off should any of the wire connections become broken in a catastrophic accident. The Isolator can be controlled by any number of switches although the usual configuration is one internal on- off switch and one external kill button.
This latter method of engine kill means that the XR is smaller and lighter than the GT and incorporates a sealed, circular connector. The Battery Isolators work by being fitted in between the negative side of the battery and the chassis ( As seen above ). The GT unit has a 40A switched power output which can be used as the main power feed for most ECUs and/or ignition systems while the XR unit outputs a low current, ‘Ignition Off’, signal which is compatible with most motorsport ECUs and PDMs. The GT battery isolator by Cartek is a compact, highly reliable and clean looking alternative to the traditional mechanical master kill-switch and has been. However, the main difference between these two units is the method used to stop the engine.
The first breaks the connection between the negative side of the vehicle’s battery from chassis/earth, thereby isolating the battery power from all electrical circuits, while the second cuts power to the engine electrics and thereby stops the engine from running.Ĭartek produces two types of Battery Isolator GT and XR.īoth systems isolate the battery from all electrical circuits, in accordance with FIA requirements, by disconnecting the negative terminal of the battery from chassis/earth. The kit contains the isolator box, internal and external actuation buttons, connection lead and safety decals. The Solid State Isolator contains two isolation circuits. The CARTEK Battery Isolator is designed to be chassis mounted close to the vehicles battery and allows the heavy current power cables to be kept as short as.
