The battery is currently sitting at 10.5 volts on shore power, and the batter level indicator on the control panel is ever so slowing moving upward (we're currently drawing around .5 amps or so), but it's taken an hour to go from bad (in the middle of the red) to the top of the red. Bad battery??

Either you have a shorted cell in the battery, or the voltage from the univolt is not getting to the battery because of some connection problem.

Check the voltage at the fuse panel and see if it is the same as the battery. If so, the battery is most likely the problem.

Shawn had wondered out loud the question of how to check if it's the battery. Anyway, he just followed your suggestion. he's off to wal-mart to get a new battery.

I want to say a big THANK YOU!!! To everyone. I can't tell you how thankful we are for the help.

ps. so much for the "new" battery the guy we bought it from said he'd put in. During all his inspections/work Shawn thinks the battery is at least 3 years old!

Sadly, that's about how long they last.

Shawn got the battery put in around midnight. We took the old one back to walmart for testing and disposal. The guy says it was dead and he wasn't sure if it would hold a charge. He could hook it up and try to charge it, but Shawn just decided to leave it ... considering the age of it.

Nicki what's the voltage at the battery now when plugged in. Test it again unplugged and with TV and let us know. The readings should tell us if you are receiving a charge from the converter and from the TV.

Shawn said it's 12.14 on shore power. He hasn't had a chance to do the others. I'm watching one of my favorite shows and might hurt him if he unplugged me!

Nicki 12.14VDC while connected to shore power is too low. Either your converter is not working or something is hindering the converter from providing the power to the battery. It is important to get the other measurements to see what changes take place to voltage levels at the battery under the different situations in order to try and diagnose the problem.

Yes, Chris is right. When you are plugged into shore power, and the converter is on, you should see about 13.6 volts at the battery terminals, assuming the battery is not totally discharged.

Once we stop for the day, he's going to take out the univolt and inspect. Any suggestions? Would a $30 battery charger plugged into the back directly on the terminals suffice until we get home? We'll be stopped for 6 days or so -- should we try and do some sort of retrofit, install a new system (not sure how hard it is to do that) or just try and get by until we get home? Remember, we just put a brand-new battery in (so we can rule that out at this point), and up until 3 days ago, the univolt seemed to be humming and working properly.

Nicki is the univolt still humming now. Yes a battery charger would help in the short term. Have you checked battery voltage with TV plugged in and running.

If in doubt about the battery, a NAPA or Autozone store can do a load test and check for a dead cell. If the battery is OK, they will give is a fast charge at high amps, that should give you a couple of days for the fridge control board to work.

this morning
he said he checked several times and all reading were between 11.5 and 11.7.
11.7 with tv connected,
with shore power it was 11.51..
he forgot to check the without power but plans on checking them all again when we unhitch today.

Shawn says he hasn't heard the univolt humming all day or last night. Our battery level has not registered in the green (good) since we left OKC.

We ended up getting a brand new battery yesterday. This morning it registered on the low side of fair.
