• Battery Isolators are designed for negative ground alternator systems with batteries
of the same nominal voltage.
• Batteries of differing voltages cannot be used.
FEATURES
• Easy to Install – The electronic isolator does not require any changes to the vehicle’s
existing wiring. It can be fitted to all 12V vehicle types.
• Priority Charging for Starting Battery – Ensures that the starting battery is fully charged
before connecting the auxiliary battery in parallel.
• Manual Override – If the starting battery is flattened and the auxiliary battery is charged, the
electronic isolator allows the batteries to be manually paralleled to jumpstart the vehicle.
• Over-Current Protection – Protects the Isolator and charging system from over current
damage, which could occur due to a short circuit in the wiring.
• Surge Protection – Provides surge protection for vehicles with electronic ignition/management
systems.
