Gun or Tears -- HELP PLZ!!!

I'm either going to take a gun to my TH or start crying in frustration.

Bought a TH in January. It sat until now. I'm trying to get it ready to go, and was going to driveway camp tonight.

Only the batteries were completely dead and had frozen over the winter. Took them to Wallyworld and had them tested and they tested fine (disaster averted, right?), so I charged them up and plugged them back in, plugged into shore power, turned on the propane, and was ready to chill for the night.

Only my CO detector wouldn't shut the F up. I immediately disconnected the batteries and took them to the charger, and disconnected shore to shut the bloody CO detector up. They both showed 65%. I plugged the TH back into shore to see what the CO detector did. It sat and flashed a green light. I thought it might be propane venting into the TH somehow, so I turned the propane off and bled the lines.

Then I went to reconnect the batteries and **** went wrong. I connected the negs and the first positive. Then I went to connect the parallel positive to the battery and sparks everywhere (yes, I know I did this wrong, don't be a dick and harp on that). So I immediately disconnected the negs, disconnected shore power, and connected the positive parallel. All good. Well, the positive terminal on the second battery was missing a chunk of the threads, but the bolt went on. I then tried to connect the first negative, and it kept sparking...small sparks, but sparking. I tried touching it on the frame to ground it, I made sure everything inside the TH was off, I let it sit for a while to calm down, and I Googled. Google said "no worries, it happens some times." So I went ahead and bolted that neg down. I then went to connect the parallel neg and it sparked like no one's business again and ate away part of the terminal connector metal again.

I've reverse order disconnected both batteries, and all is good for now, but I'm ready to put the whole thing up for sale as "new never used." Short of hauling it into the RV dealer and telling them to fix it, I don't know what to do. HELP!!!!!!! I've been trying to get answers/help from another forum for more than 24 hours, and the assistance provided has ranged from "go search the forum" (which I did) to "is the dog farting?" I get that I'm a total Noob, but I'm trying to learn without killing myself in the process.

  • I wonder how Wallyworld tested dead batteries that were frozen at one time. Completely charge the batteries and take them elsewhere for a proper testing.
  • If those batteries froze solid and the sides are bulged even slightly replace them. The plates suffered damage and failure is in their future....at the most inopportune time. Plugging into shore power should provide 12volt power through the converter so the battery should not be necessary to be hooked up at the same time.


    Your only complaint was the CO detector, but everything else worked correctly? Furnace being the important thing in the cold weather. If that is the case then everything indicates the fault is at the batteries. To remove batteries disconnect the NEG first, to reconnect connect the NEG LAST.

    Something is always on in the RV. The radio, and propane sensor stay on, and will cause a spark when you hook up the battery. but shouldn't melt the post.

    But as others have said. Stay calm, and get it looked at. You will be fine.

    I do have a suggestion. Next winter. Remove the batteries. First take a picture of how they are connected. But remove them and store them inside to protect them.

    The CORRECT name for the Propane detector is "Explosive Gas Detector"

    Propane. Methane. Butane. Hydrogen. Alcohol. Gasoline Any vapor that goes BOOM.

    One word of warning.
    Just read the story of a man who bumped a knob on his stove And when he figured it out he turned every knob. INCLUDING THE ONE THAT MAKES A SPARK.. Only damage was temp hearing loss and the hair on his arm.

    Last summer... Same story.. Only it was the hair on his legs.
    IF YOU or the detector SMELL explosive gas DO NOT TOUCH THAT KNOB.
  • Welcome to the forum. Sorry to hear of your frustration but it does make for an entertaining adventure, which a decent sense of humor will have you telling on yourself one day after you get it all sorted out.

    Although your batteries tested ok, lead acid batteries do not like being drained completely dead and they especially don’t like being frozen, so they are likely going to have a much shorter life than normal. Their newness saved you in the short run.

    There is a small and inexpensive tool you will find very useful in the future for dealing with electrical issues. That is a volt-ohmmeter. All you really need is a cheap one in the $5-$10 range, although the more expensive $40-$50 ones are more capable. You can use it to test for all kinds of electrical problems ranging from which lead is positive and which negative to is there power here to whether the shore power is useable (voltage 110-130). In the sparking case, it could have helped show you you were connecting the right wires to the right terminals. You might seek out a teenage science nerd to show you how to use it.

    Your new TH is a new adventure, and does come with guaranteed adventures in riding the learning curve. We’ve all been there.

    Nice. People rant about unethical practices by dealers and here's an advocate for dishonesty in claiming warranty coverage for what was clearly not a warranted defect.
  • I have no answers but WELCOME to the forum. Stay calm. A new RV is a lot to learn.

    Hang in there ~ One new thing atta time ~~ Good Luck
  • Batteries release hydrogen when charging.

    Hydrogen is detected by carbon monoxide detectors. That's the likely reason you had the false CO alarm.

  • You have Dual 12V batteries......connect ALL positive cables FIRST...then connect the negative to negative cables THEN Neg to ground cable
