We have had our 177 for about 6 months.  The first couple trips everything went fine, but the last few outings, when we are plugged into campground hookups (30amp), everything works but the battery drains quickly.  This leads to the ignitor in the fridge to quit working too.  I have checked all breakers, replaced both 40 amp fuses (both were good) and checked all others.  GFCI above sink checks out fine too.  The battery charges fine when plugged into the truck driving, but won't stay charged.  I even switched out the battery- am I missing something in the control panel???  WE are at our wits end.  I've searched other posts in here but can't find an answer.

sounds like somthing draining battery . Might be a long shot but I read some place about electri brake causing problem  being energized all the time.did you check at broke junction maybe cabled got pulled. Just a suggestion.GBA!!SVJ

It could be a bad power converter. That's what provides DC power and battery charging when plugged into shore power. It's in the bottom of the power center. Do you have a multimeter?

Should still be in warranty (assuming you bought it new).

If something is draining the battery fast enough to negate the charging from the power converter, the converters fan would be running and you'd notice that.  Also, whatever was draining it would be quite hot since the power converter puts out about 45 amps max.

I've checked the trailer brake disconnect and all is good.  The only thing that stays on is the factory installed radio.  Radio isn't on, but display stays lit.  We bought used, but it's only 3 years old.  Going to buy a multimeter today to test.  Is this something I can replace myself or need to take to dealer if it's bad?

I agree with Mikes. It’s likely a bad power converter.  I’m fairly handy, but I’m not any kind of RV technician or expert. Yet, I found replacing mine on my fifth wheel a few years back was very easy. If you determine yours is bad, I think what would make it easiest is to replace it with the exact same unit. That way it’s essentially plug-and-play, and you can take pictures to just make sure you put the wires back where they go.  You can probably find it on Amazon, or any of the big RV suppliers.

I found it interesting that you stated the refrigerator needed the battery to function. We were camping without electricity running the refrigerator off the propane gas.  But when the battery died, so did the frig.  I thought it would just use gas??

The fridge runs off propane, but I think the igniter needs 12 V to ignite the propane.  Similarly, when the power converter went out on our fifth wheel, even though we were plugged into shore power, the 110 V air-conditioning wouldn’t work. That’s because the thermostat requires 12 V to function, including cycling the air-conditioning on and off. The emergency solution was to buy a portable 12 V charger, which provided enough electricity to run the thermostat, and then the air-conditioning would run fine on its own off of 110. I now carry a portable charger with me for such situations, as well as it can be handy to have a back up charger for other reasons too. I also carry a spare battery, which I can keep charged with the portable charger, and that has come in handy as well.
