Alternator; 100 Amp; 75 Idle; 1 Volt Pulley; Natural; 2" mounting flange
Upgrade your Full Size Jeep’s electrical system with this Powermaster 100 amp alternator. The alternator sits at the front of your engine and keeps your battery charged while powering all your electrical parts—like headlights, heater, radio, and off-road lights. This high-output alternator gives you extra power for modern upgrades, so you don’t have to worry about dim lights or a dead battery.
Alternator comes with a single-groove pulley. If you have a double-groove pulley, you will need to change them over (they are a direct swap). If you have an older model vehicle with an external voltage regulator, you can use this alternator with some minor wiring changes under the hood.
If you notice your headlights getting dim or flickering, your battery dying often, your dash warning light turning on, or your electrical accessories not working right, these can be signs your alternator is failing. Upgrading to this 100 amp alternator helps keep everything running smoothly—even if you’ve added extra electronics to your classic Wagoneer, Cherokee, Grand Wagoneer, or J-Series Truck.
