Solange Émile A Blue Sea Automatic Charging Relay (ACR) is a device that manages the charging of multiple batteries from a single alternator. It ensures that all batteries are charged simultaneously and prevents them from being overcharged or discharged. The Blue Sea ACR uses a voltage-sensing circuit to monitor the voltage of the batteries and alternator. When the alternator is running and the voltage reaches a predetermined level, the ACR closes a relay, which connects the alternator to the batteries. When the voltage drops below a certain level, the ACR opens the relay, disconnecting the alternator from the batteries. This prevents the batteries from being overcharged or discharged and extends their lifespan.
Blue Sea ACRs are available in various models to accommodate different battery and alternator configurations. They are easy to install and can be used in various applications, including marine, RV, and automotive.
Wiring a Blue Sea ACR is relatively simple. The positive terminal of the alternator is connected to the ACR’s alternator input terminal. The positive terminals of the batteries are connected to the ACR’s battery output terminals. The negative terminals of the batteries are connected together and then to the ACR’s ground terminal. Once the ACR is wired, it will automatically manage the charging of the batteries, ensuring that they are all charged simultaneously and preventing them from being overcharged or discharged.

These are just a few of the key aspects of a Blue Sea Automatic Charging Relay wiring diagram. By understanding these aspects, you can ensure that your ACR is installed correctly and that your charging system is operating properly.
Alternator
The alternator is a key component in the Blue Sea Automatic Charging Relay (ACR) wiring diagram. It is responsible for generating the electrical power that is used to charge the batteries. Without the alternator, the ACR would not be able to function and the batteries would not be charged.
The alternator is connected to the ACR through the alternator input terminal. The ACR monitors the voltage of the alternator and the batteries, and controls the flow of current between them. When the alternator is running and the voltage reaches a predetermined level, the ACR closes a relay, which connects the alternator to the batteries. When the voltage drops below a certain level, the ACR opens the relay, disconnecting the alternator from the batteries. This prevents the batteries from being overcharged or discharged.
The size of the alternator is important in determining the amount of current that can be supplied to the batteries. A larger alternator will be able to supply more current, which can be helpful in charging multiple batteries or large batteries. It is important to select an alternator that is properly sized for the application.
The alternator is a critical component of the charging system and the Blue Sea ACR wiring diagram. By understanding the role of the alternator, you can ensure that your charging system is operating properly and that your batteries are being charged correctly.
ACR

Battery Isolation
The ACR isolates the batteries from each other, preventing current from flowing back from one battery to another. This can happen when one battery is discharged and the other is still charged. Battery isolation is important to prevent overcharging and discharging of the batteries.
-
Voltage Monitoring
The ACR monitors the voltage of the batteries and alternator. When the alternator is running and the voltage reaches a predetermined level, the ACR closes a relay, which connects the alternator to the batteries. When the voltage drops below a certain level, the ACR opens the relay, disconnecting the alternator from the batteries. This prevents the batteries from being overcharged or discharged.
-
Current Control
The ACR controls the flow of current between the alternator and the batteries. It ensures that all batteries are charged simultaneously and that no one battery receives too much current. Current control is important to prevent damage to the batteries and to ensure that they all have a long lifespan.
-
System Protection
The ACR protects the charging system from damage. It includes fuses and diodes to prevent short circuits and overloads. System protection is important to ensure that the charging system is reliable and safe.
The Blue Sea Automatic Charging Relay is a critical component of the charging system in a boat or RV. It ensures that all batteries are charged simultaneously and prevents them from being overcharged or discharged. The ACR also protects the charging system from damage. By understanding the role of the ACR, you can ensure that your charging system is operating properly and that your batteries are being charged correctly.
Batteries
Batteries are a critical component of any electrical system, providing the power needed to operate the various electrical devices and appliances. In a boat or RV, the batteries are typically charged by the alternator, which is driven by the engine. However, when the engine is not running, the batteries must be able to provide power to the electrical system. This is where the Blue Sea Automatic Charging Relay (ACR) comes in.
The ACR is a device that monitors the voltage of the batteries and alternator. When the alternator is running and the voltage reaches a predetermined level, the ACR closes a relay, which connects the alternator to the batteries. This allows the alternator to charge the batteries. When the voltage drops below a certain level, the ACR opens the relay, disconnecting the alternator from the batteries. This prevents the batteries from being overcharged or discharged.
The ACR is an important part of the charging system in a boat or RV. It ensures that the batteries are always charged and ready to provide power to the electrical system. Without the ACR, the batteries could be overcharged or discharged, which could damage the batteries or shorten their lifespan.
Here are some real-life examples of how the ACR can be used:
- In a boat, the ACR can be used to charge the batteries from the alternator while the engine is running. This ensures that the batteries are always charged and ready to provide power to the electrical system, even when the engine is not running.
- In an RV, the ACR can be used to charge the batteries from the alternator while the RV is being towed. This ensures that the batteries are always charged and ready to provide power to the electrical system, even when the RV is not connected to shore power.
Understanding the connection between batteries and the Blue Sea Automatic Charging Relay wiring diagram is important for ensuring that the charging system in your boat or RV is operating properly. By understanding how the ACR works, you can ensure that your batteries are always charged and ready to provide power to the electrical system.
Battery Isolator

This can cause overheating, damage to components, and even fire.
Fuses are designed to break the circuit and stop the flow of current in the event of a short circuit. They are typically made of a thin wire that melts when the current exceeds a certain level. This breaks the circuit and prevents damage to the electrical system.
In a Blue Sea ACR wiring diagram, fuses are typically placed in the positive and negative lines of the electrical system. This ensures that the circuit is protected from short circuits on both the positive and negative sides.
The size of the fuse used in an ACR wiring diagram is important. The fuse should be large enough to handle the normal operating current of the system, but small enough to blow in the event of a short circuit.
Understanding the role of fuses in a Blue Sea ACR wiring diagram is important for ensuring the safety and reliability of the electrical system. By using the correct size and type of fuse, you can protect the electrical system from damage in the event of a short circuit.
Diodes
In a Blue Sea Automatic Charging Relay (ACR) wiring diagram, diodes play an important role in preventing current from flowing back from one battery to another. This is important because it ensures that each battery is charged independently and that one battery does not drain the other.
-
Facet 1: Role of Diodes in ACR Wiring Diagrams
Diodes are semiconductor devices that allow current to flow in only one direction. In an ACR wiring diagram, diodes are placed in the positive and negative lines of each battery.
