A Blue Sea Automatic Charging Relay (ACR) is a device that allows two or more batteries to be charged from a single alternator. This can be useful in a variety of applications, such as boats, RVs, and off-grid solar systems. ACRs work by sensing the voltage of the batteries and connecting them to the alternator when necessary. This ensures that all of the batteries are charged to the same level, preventing one battery from being overcharged while another is undercharged.

Wiring an ACR is relatively straightforward, but it is important to follow the manufacturer’s instructions carefully. The following steps will provide a general overview of the process:

Identify the terminals on the ACR. There will typically be four terminals: two for the batteries, one for the alternator, and one for ground.
Connect the batteries to the ACR. The positive terminal of each battery should be connected to one of the battery terminals on the ACR. The negative terminals of the batteries should be connected together and then to the ground terminal on the ACR.
Connect the alternator to the ACR. The positive terminal of the alternator should be connected to the alternator terminal on the ACR. The negative terminal of the alternator should be connected to the ground terminal on the ACR.
Test the ACR. Once the ACR is wired, it is important to test it to make sure that it is working properly. This can be done by starting the engine and checking the voltage of the batteries. The voltage of all of the batteries should be the same.

Benefits of using a Blue Sea ACR:

Prevents one battery from being overcharged while another is undercharged.
