    Please contact us to purchase. We want to ensure you are getting the kit and system needed for your application.

    A Cyrix based alternator charger will only be able to bring a house battery bank up to about 80% State Of Charge.

    Slow Flash – Batteries detected, but not connected

    Solid (or fluttering) – Batteries connected

    Wiring Diagram

    Alternator connections points can vary widely. Customers may need to contact their manufacturer for specific details and/or provide manufacturer-approved fuses or buss bars for installation. Customers are responsible for ensuring warranty compliance.
