Arco Starting & Charging AS12 Zeus Alternator Shield Protection Device - 12V

The Arco Zeus Alternator Shield AS12 is engineered to protect high-output 12-volt alternators from damaging voltage spikes and battery disconnect events. This essential protection device safeguards your alternator's internal diodes and voltage regulator from catastrophic failure caused by sudden load dumps or battery disconnection while the engine is running.

Key Features:

• Protects against voltage spikes up to 150+ volts that can destroy alternator components
• Guards against damage from battery disconnect events during operation
• Designed specifically for high-output alternator applications
• 12-volt system compatibility
• Simple inline installation between alternator and battery
• Solid-state protection with no moving parts

Load dump events occur when a battery becomes disconnected while the alternator is actively charging, causing a dangerous voltage spike that can instantly damage or destroy alternator diodes, the voltage regulator, and other electrical components. The Zeus Alternator Shield absorbs these transient voltage spikes, extending alternator life and preventing costly failures in demanding marine, commercial, and high-performance applications.
