Name this electrical part

[mdnja]

Hello,

I have a 2019 Baystar 3626. 2 years ago, we had the coach plugged in at home and the outside temp dropped to 19 degrees. The BIRD started clicking on and off. A quick search indicates that there had been a drop in voltage. Long story short, a trip to the dealer showed that the BIRD was bad and replaced it. Flash forward to a couple of days ago, plugged in and the temp dropped - BIRD clicks on and off until it apparently dies. No more clicking and the voltages on both sets is dropping. New BIrD ordered.

Now, on to my question the part shown in the picture is mounted in the propane compartment on the wall adjoining the battery compartment. If you look closely, you can see 2 green LED’s and 2 red LEDs. Before the first BIRD failure, both green lights were lit. After replacing the BiRD, both red LED’s were lit.

Can anyone identify what this part is? It is part of the charging system as the green LED’s would blink as the BiRD clicked.

I tried Newmar support and couldn’t get a straight answer. You’ll have to rotate the pic. The orange and white wire are on top.

Thanks in advance for any assistance!!!!

Welcome to the forum,mdnja
Here is a link with many BIRD charging systems for your batteries.
It come from this large sticky top of forum page.
Your Owners Guide may have a answer to your question also. Look on page 37 for explanation of your charging system for all your batteries.
I am sure others with your coach will step in also.

Thanks! Alas, none of those sources proved fruitful. Believe me, I’ve searched this forum up and down. I’ve searched the manufacturer of the BIRD. I’ve searched NEWGLE. I can’t find this part anywhere!

I , have to ask , Have you dismounted the boxes and looked for a part number or manufacturer name ?
Could be on the back side or hidden edge.

Have you any idea where the any of the wiring goes ; particularly the two white wires, that I've marked with arrows.

Great idea! Those white wired are grounds. They are screwed into the frame just outside the picture.

Now you really got me thinking , multiple ground points .

Real question is Where do the ORANGE wires go ???

I have a device that looks similar to your photo mounted in the house battery compartment on my 2016 Dutch Star. It is a thermostatically controlled relay that heat traces the exposed water line going to the full wall slide. The Red LED indicates the ambient temperature is above 40 degrees and the relay is open. The green LED indicates the ambient temperature is below 40 degrees and the relay is closed.

Below is a link to an old thread with additional information (posts 19-22). I also attached a cut sheet with wiring and operational information on the relay.

... Maybe this is your mystery device???

I have the same 2 devices mounted on my 2019 CS 3513. I have a Full Wall slide with a kitchen and because of cold weather exposure when slide is out, Newmar wrapped the water lines and ice maker line with heater tape connected to those boxes. They are low temp activated and you can fine more info on the forum about their use. I DO NOT have the winter package, but still have these installed.

Ok , mystery solved to a point .

Question now would be , why it flickered when the BIRD did .

Best guess ; without a full manufacturers specs ; would be a low battery cut out , in the solid state relay, to prevent draining the coach batteries completely.

Battery voltage low , relay turns off power to the heat tape , BIRD starts charging , relay turns back on.

The tell tale proof that they are installed by Newmar are the self tapping screws....they install everything with them

Here is the Manufacturer & Part number

This is interesting. What a great resource this forum is.

I will research the waterline thing. That would make sense because the temps were well below freezing when the BIrD went crazy. Perhaps there is a malfunction in that waterline setup.

As far as the blinking goes, I can add that the interior lights would dim when the BIRD clicked. As did the fan on the furnace change tone. I wonder if all of these things are 12v DC, thus affected by the BIRD?

Also, another update... remember I said that I though the BIrD died because it stopped clicking and voltages on the batteries were slowly dropping? I checked them today and both read 13.1 volts.

Could it be that the BIrD ‘reset’ itself and when the voltage dropped to 12.6, it started working again?

A bit more information, I started the engine during my normal weekly ‘run the motors’ and the voltages on Borge batteries when to 14.1. Which, incidentally, is what used to show when plugged in to shore power way back when before the first time this happened.

Thanks all for your time!

Thank you so much Kshock! I don’t have the winter package, either, but what you are saying makes total sense. Where I thought it was part of the charging system, it not.

And, it makes sense where they mounted them in the propane compartment because it’s exposed to the outside.

Thanks again! Dan
