RAM Ram 3500 2019-present Electrical Specifications

The 2019-Present Ram 3500 features a robust electrical system with a 12-volt battery, alternator output ranging from 220 to 240 amps, and dual batteries in certain configurations. The system supports advanced features like trailer brake controllers, integrated trailer light check, and multiple auxiliary switches. It is compatible with both standard and optional electrical accessories, ensuring reliable performance for heavy-duty tasks.

Regular maintenance includes checking the battery terminals for corrosion, ensuring the alternator is functioning correctly, and inspecting wiring for wear or damage. The battery should be tested annually, and connections should be tightened as needed. Fuses and relays should also be checked periodically. Adhering to the maintenance schedule in the owner's manual is crucial for optimal performance.

To replace the battery, first, disconnect the negative terminal, followed by the positive terminal. Remove the battery hold-down clamp and carefully lift the battery out. Install the new battery by placing it in the tray, securing it with the hold-down clamp, and reconnecting the terminals (positive first, then negative). Ensure all connections are tight and free of corrosion.

Start by checking the battery voltage with a multimeter; a reading below 12 volts may indicate a dead battery. Inspect fuses and relays for any blown components. If the alternator is suspected, test its output voltage (should be 13.5-14.5 volts). For persistent issues, consult the owner's manual or seek professional assistance to diagnose and resolve the problem.

To optimize performance, ensure the battery is fully charged and free of corrosion. Use high-quality electrical components and accessories. Regularly inspect wiring for damage and ensure all connections are secure. Avoid overloading the system by using compatible accessories and following the manufacturer's guidelines for electrical load management.
