Dumb Question!!!!!

OK so I'm getting older and can't remember some stuff...but....when we are camping and are on campground electric...do we need to have the batteries turned on or turn them off with the battery disconnect switch? If they are turned off, should the converter charge the batteries?

I know that the frig requires 12v to operate - is that supplied thru the converter???

We are having an electrical situation with our frig and I'm trying to figure out if it is actually the control board of the converter.

Leo is NOT electrically savvy and does not want to get involved.....so guys be nice to this ole' broad!

Kathy

I just checked mine. With battery disconnect switch off and on shore power. Frig. works on gas and 120V and 12V lights work. Battery not charging.

OK but I was under the impression (and was told) that the frig needs 12 volt to operate - so is that from the convertor or the battery???

I leave my battery switch on most all the time. The convertor would supply power to all your 12V needs if the switch is off I believe.

That's the way mine is working right now shore power on battery off. I have older converter that can over charge and boil battery dry.

If your battery disconnect is in the off position you will not be charging them when plugged into 110 source. If plugged in to 110 your 12 volt dc comes from converter. If not plugged into 110 it comes from battery. I would check fuse for fridge in converter. It more than likely on a circuit with your furnace. It should be labeled. There are no dumb questions if you are above 60 like me. They are called senior moments because we have seen so much. Things are in there and we just can find them when we need them.

Either way you should have 12 volt power the newer fridges need 12 volt to power the control system for the fridge that's why I really like my old dumb fridge! Pretty much if your interior lights work you have 12 volts.

Kathy,

You are amongst many of us "I'm getting older and can't remember"....

You asked a few questions, inserts in red as this might help.

With your newer converter (most likely a 3 stage unit) you can leave the disconnect switch on. This way it will charge the battery if it needs it and not cook the battery to death. And on your newer converter it will will create 12 VDC to power up the entire camper if plugged into shore power even with the disconnect off.

If they are turned off, should the converter charge the batteries? If the battery disconnect is off, No battery charging is occurring and the battery cannot supply any voltage for the camper to use. The battery disconnect normally totally disconnects all inside 12 volt devices from getting power from the battery. Power cannot go into the battery or come out. It is truly "disconnected" from the inside devices and the converter. Normally the only thing that works with the disconnect off is the emergency break away switch for the brakes and a power tongue jack as some times they are wired direct and not through the disconnect.

I know that the frig requires 12v to operate - is that supplied thru the converter??? If battery is off, 12v comes from the converter if plugged into shore power. If battery is on and plugged into shore power, the 12v power comes from converter primarily. The converter is plenty big enough to run just the fridge if it is working correctly and still charge the battery.

If the battery disconnect is on and the converter is not working, then the battery will feed 12 volts providing no fuses are blown.

Give us a model and make on your converter and we can look it up. Can verify if it is a 3 stage unit or not.

If it's a 3 stage it won't hurt to leave connected when on shore power. The 3 stage is a smart chsrger. Meaning it won't over charge the battery.

This is late to the party, but will just say that at the moment I have my 1996 T-2053 connected to shore power (my house) and I have no battery attached to the trailer and I have both ac and dc power. The house current is going to the converter and in turn the converter is supplying the dc.

Kathy,

The only time I put the battery disconnect switch into the OFF position is when we put the trailer into storage between camping trips. This is primarily so the 12v items, such as radio, detector, etc. that are on all the time don't drain the battery.

Any time we're plugged into shore power I have the battery disconnect switch in the ON position, to keep the batteries charged.

Actually, anytime we pull the trailer out of storage, I turn the battery disconnect switch to ON. But you know us, we hardly ever dry camp, so we're almost always plugged into shore power when the trailer is home or in a campground and always have the disconnect switch to ON.

You said in your OP that you're having refrigerator problems.
What problems are you experiencing with your refrigerator?

Hutch

P.S. Here's a link to WFCO's WF-8955 55 Amp Power Center web page.
Your converter is a 3 - state (similar to our, which has the Charge Wizard), so keep the disconnect switch on when plugged into shore power will charge the battery and also prolong the life of the battery by not overcharging it.

FYI - if you're looking to recharge the battery using your Honda generator when dry camping, you want to see if your converter has a push button to put the converter into Boost so it will charge the battery faster from the generator. If you don't do that, you may not get a sufficient battery charge from the Honda generator in the few hrs DEC campgrounds allow you to run them.

Ok here's an even dumber question. I just got a '97 Solaris T-2553. Where is the battery disconnect switch located?

Not sure if the '97s came with a battery disconnect switch.
From what I remember our '99 Solaris didn't have one, but our 2005 did.
Not sure when Sunline started installing the battery disconnect switches on their units. Sunline Fan would probably know.

My 1996 T-2053 doesn't have it. I have one on my 1983 T-1550 done as a mod. by previous owner. He also did a microwave.

I was told by my Dealer the 2004 models was the start of the disconnect switch. Some of the late 2003's may have had them too. Those before the disconnect switch needed to unhook the battery negative cable when in storage. Or get fed up with dealing with the battery case straps and install their own disconnect.
