If the starting battery is flat and the auxiliary battery is charged, the battery isolator can be used to connect both batteries to allow jumpstarting. Once the Battery Isolator has been correctly installed and tested it will function automatically to charge the auxiliary battery. 60 seconds after the voltage falls below 12.8V, the blue ‘Charging’ LED will turn off and the isolator will disconnect the two batteries from each other. The isolator will now detect that the batteries are being used. Once the Isolator is in ‘Charging mode,’ turn the engine ‘Off’, then switch the headlights and other accessories ‘On’.This will allow the alternator to generate more current. If the isolator does not go into ‘Charging mode’ within a few seconds, increase the engine RPM to a fast idle.Within a few seconds the blue ‘Charging’ LED will turn on indicating that the starting battery is above 13.4V and the isolator will start charging the auxiliary battery. With the installation complete and the engine ‘Off’ only the red ‘Power’ LED should be on.Connect all of the auxiliary loads (phone, lights, stereo, refrigerator, etc.) to the positive battery terminal of the auxiliary battery, use appropriate circuit protection fuses.Connect a length of cable (of suitable size, commonly 2 B&S) from the vehicle’s chassis or engine block to the negative terminal of the auxiliary battery as a ground cable (Earth), the isolator should now show a solid red ‘power’ LED.Reconnect the starting (main) battery’s negative cable (Earth), the isolator should now flash the red ‘power‘ LED.Connect the isolator’s ‘Earth’ wire (small black wire with ring terminal) to a suitable chassis bolt or screw, ensure the ring terminal will make a good electrical connection by removing any paint.Do not over-tighten the terminal studs on the electronic isolator.
If using (Fused distribution terminal) the connection from the battery isolator should be made to main (large) fuse stud. The connection at the Auxiliary battery should be fused using a ‘Fused’ battery terminal or a 150 Amp fuse or circuit breaker mounted inline. Connect a length of cable from the ‘AUX’ (+) terminal on the isolator to the positive battery terminal of the auxiliary battery.Connect a length of cable from the ‘MAIN’ (+) terminal on the isolator to the positive battery terminal on the starting (main) battery.Note: To prevent the loss of vehicle electronic memories, radio presets & security codes, it is recommended that an “Electrical System Memory Protector” be used. Disconnect the negative battery cable (Earth) from the vehicle’s starting battery.Cable lugs should be crimped or soldered to the stripped battery cable and then protected with the heat shrink. To make the electrical connections, battery cables will need to be made to the correct length using cable lugs and heat shrink. Installation of the Battery Isolator– Connection 20mm² (4 B&S) for rear of vehicle / trailer mounted auxiliary batteries.14mm² (6 B&S) minimum for engine bay mounted auxiliary batteries (up to 3m).Auxiliary battery cradle & battery clamp.Charged auxiliary battery - Deep cycle recommended for most applications.Surge Protection - Provides surge protection for vehicles with electronic ignition/ management systems.Over-Current Protection – Protects the Isolator and charging system from over current damage, which could occur due to a short circuit in the wiring.

Easy to Install - The electronic isolator does not require any changes to the vehicle’s existing wiring.Batteries of differing voltages cannot be used.Battery Isolators are designed for negative ground alternator systems with batteries of the same nominal voltage.Follow all vehicle manufacturers’ instructions.Vehicles must be in “NEUTRAL ”or “PARK ”, park brakes “ON ”.BATTERIES PRODUCE EXPLOSIVE GASES - Ensure no sparks or flames are present.PLEASE READ THESE INSTRUCTIONS COMPLETELY PRIOR TO INSTALLATION.
