Clicking, like a relay

[MIDMONDN]

I have a clicking sound upfront below the floor around the drivers area.
Sounds like a large relay of some kind and its cycles around 15 - 20 minutes. Can anyone tell me what it is.

Is this when connected to shore power? Where is your converter/charger? Further investigation needed.

Need more data, what year MH and are you sure it's below the driver? Check the fuse box on Drivers side first storage compartment area, also the Jacks hydraulic pump in that area if it's there.
Is it when the engine is running only, how about if you open circuit the chassis battery, then try the coach battery to see what circuit it's on.

More data, more data, more data please

Thanks guys for the intrest

My 27N is titled as a 2017 but I just found out the chassis is a 2016.

The clicking is only heard while the engine is off (allthough if it did cycle/click while the engine is running I dont know if I would here it).

And I can here the clicking with or with out shore power hooked.

I am very certain the sound is coming from under the drivers area below the subfloor behind the fuse panel.

Thanks Again

(I am wondering if it could be calling for additional charge for the chassis
Battery)

With no engine, shore, or generator power, the solenoids shouldn't be triggered. The battery isolation solenoid would only connect when a charging voltage is detected.

Do you have a converter/charger or an inverter/charger, or a separate inverter?

Thanks Bill
Actually I did have a converter - charger but just installed a charger - inverter same sound with both set ups.

So did you try to isolate the 12v source by killing the chassis battery and or the house battery?
Also, do you have your foot on the brakes at the time you here the clicking noise?

I have a similar clicking sound coming from the same area of my 2014 Sightseer. Located in the basement compartment in that area is an electrical compartment - taking the cover off, there are a bunch of circuit breaker type buttons. Behind the panel with the buttons are a bunch of relays and solenoids.

The sound, as explained by a Winnebago Tech, is a relay located in that compartment that maintains the voltage on the coach battery from the house batteries when the motor is off - similar to a TRIK-L-START. When your rig is parked, and coach battery voltage goes down, relay closes and brings charge up on coach battery from house batteries. Click is when relay closes. Tech says noise is normal / not to worry. So long as it doesn't sound like machine gun, all is well.

When at home, my rig is connected to shore power. I've watched the coach battery voltage and when it drops to about 12.8, I hear the click and voltage goes back up to 13.6 . I don't hear the relay open but with time coach voltage slowly drops. (That was a very exciting afternoon - sort of like watching paint dry.)

My rig is either on the road or connected to shore power so I can't say what would happen if no 120V was supplied to the rig. If the relay continued to try to maintain the coach battery, all batteries would eventually die.

When we first bought our 2012 Winnebago Journey it had a faulty transfer relay.

It kept trying to transfer to battery power, and then it would switch back to shore power. Didn't matter whether it was plugged into shore power or unplugged.

Once the dealer replaced the transfer relay with a new one, it went away.

Hope that helps.
