"Loud Noise From '15 DS Transfer Switch Box?

I've just returned from spending a few days in my new '15 Dutch Star 4369 and need help in resolving two major concerns thus far: 1) A loud "thump"
noise (like a slamming compartment door...actually shakes the coach) that
seems to come from the area of the transfer switch box. While it occurred
over a half-dozen times during my presence it may well have taken place
more times. I switched to my GenSet for several hours and found that the
same noise happened, as when plugged into 50A service in the State Park.
At home I keep my coach plugged into 50A service, but have yet to hear the noise, although it may be occurring when I'm not present. I called this
to the attention of a Customer Relations Tech in Nappannee, and he could
offer no help, except to bring it in and expect the noise not happen while
there. He said he was not aware of any similar concern expressed by other owners. Does anyone have a CLUE as what my problem is? While it may
be quite risky to delay hauling the coach in, quite possibly in time I will
discover the culprit. 2) My sewer hose is a Rhino-Flex and even after
purchasing the 90-degree fitting to turn down into the floor opening, I'm
not able to attach the hose and have it run through the opening, so that
I can close the compartment door when in use. Is ANYONE using the
Rhino-Flex...if so, how have you managed? If there's no way this one will
work, WHAT will? I'd be most appreciative of any help I can get. Thanks!
Larry

Larry,

What you are probably hearing is the BIRD (Bidirectional Relay) opening and closing. It is malfunctioning if it is making very load noises (booms). Although I cannot explain its function totally, it has to do with allowing each set of batteries (house and chassis) to be charged. When it senses that one set is low it may close off the other set so that low set can charge. When it senses a set of batteries is fully charged it closes the charging circuit to that set.

Maybe the power at the State Park was not as clean or strong as at home and it made the relay work more at the Park, and not at home????

You should hear the BIRD open and close but not a big bang like you are experiencing.

Maybe someone else has a different idea of what is happening.

Sounds serious enought to get it inspected. If you are handy with electric you can check it yourself.i have retired mine on two coaches with a progressive surge proctor.
1 make sure it is unplugged
2 disconnect the house batteries
3 make sure that the auto gen is not engaged actually you can flip the breakers on the gen
The transfer switch should be in the electric bay, while there you can check that the electric reel is not making the noise
Uncover the switch and make sure with a gage no electric then tighten each electric cable might be the inside of the switch is loose.
Hope that it is simple to fix.
Can't help you on the rhino as I would think that you would have to take the fitting off. Mine is the same way.
I have a 2015 London Aire both items should be the same.
I can hear my switch but not what your sounds like.

Larry the outlet sewer valve on your coach swivels up and down. After putting the 90 elbow on the outlet valve, push down and the bottom of the elbow should align right in the center of the floor opening. I also use the Rhino hose and fits perfectly when you lower the outlet valve.

I didn't think that the 2015 has the Bird system, I could be wrong but I have read about another system and can't remember the name but I think it is different. My Monaco had the Bird system

Larry I believe he is talking about the storage compartment not enough room to close the storage compartment door.

Steve, you could very well be correct. I don't have my new coach yet, so that may be a change that I am not aware of - for a couple more weeks!

The 2015/16 should have the BIM system. BIM and BIRD do the same thing. They just do it a little differently.


Because the problem does not present itself when connected at the house, consider doing nothing until you stop at a few more CGs. One never knows what electrical problems one can run into at each CG.

When you hear the slamming noise are you loosing power? This happened to is last weekend. We were awaken during the night with a loud slamming noise. The transfer switch was going off and then coming back on. Long story short, our progressive Industries EMS-HW50C ground wire in the plug shorted and melted.

Many thanks to ALL! I'm a "hands-on" guy, but as everyone, with limitations. Never heard of the BIRD system...don't believe it's on the '15 DS 4369, either. May have to place a recording device in the transfer switch area. I hoped the noise wouldn't occur with the GenSet running, but it did...so that rules out a problem with the park's service. I thought I'd tried every conceivable twist & turn with the Rhino-
Flex, but I'll give it another try. Again, thanks. Larry

Are you saying you can't get it on the valve or are you talking about the storage tube in the back with a small door

Loud Noise From '15 DS Transfer Switch Box?

Steve...I'm saying - inside the water compartment - I cannot install the Rhino so that it will go directly downward through the hole, in order to
close the compartment door while it's in use. As far as the storage tube/
container, I have to remove the fittings in order for the hose to fit into that
storage compartment, then fish it out with the awning rod. Wonder why it wasn't made a larger diameter?

Loud Noise From '15 DS Transfer Switch Box?

Tikitom...thanks. I wasn't losing any power...the ACs were running, the
TV at times, etc. No evidence of losing any power. Did you experience the
"slamming" noise a # of times, or only the once? As I mentioned, in my
case it happened over half-dozen times. Pretty scary, and rightly so. It's
hard to believe I haven't had some "melting", as you did. Any damage to
appliances? You make the repair(s)? Would a Surge Protector" have pre-
vented such damage from occurring? Respond, if you will...and again,
thanks! Larry
