The Jeep Cherokee XJ is a fantastic platform for overlanding and off-road adventures, but its factory electrical system was designed for a simpler time. Add a winch, a bank of LED lights, a powerful sound system, an air compressor, and auxiliary lighting, and you will quickly discover the limits of the stock 90-amp alternator and single battery. Voltage drops, dimming lights, and the dreaded "accessory-induced stall" at idle are all signs that your XJ is crying out for an electrical upgrade. Installing a high-output alternator paired with a dual battery system is the definitive solution, providing reliable power for every gadget you can bolt onto your Cherokee.
