FR3 Clicking

[Captin53]

I own an FR3 30ds. When the batteries are fully charged I hear a clicking noise from the battery compartment. Any ideas?

An occasional clicking or what? Is it truly a "click", which usually means a softer, quieter noise? Or is it more of a louder "clunk"?

What year FR3 do you have?

In the battery compartment you should have a device called a Battery Control Center. Which one do you have?

The Motorhome is a 2015 with a Battery Control Center. I think the clicking (not Clunk) comes from the Control, Center.

The interconnect relay (solenoid) is inside the BCC and it will change state (energize/deenergize) as applicable when on shore/generator power and when engine is running for cross charging (coach/chassis) batteries to control over charging. Normal operation. If one of the conditions above is not the case; I haven't a clue.

The clicking sound you’re referring to is similar to the sound you hear when you disconnect the batteries on the battery control center. If so, then @bubbles described normal operation.
