Best Of

I have a new to me T@B S Max 2015 in which I purchased this winter. It has been a rough road learning by mistakes and figuring out out my first RV. I had no idea it would be this big of a money pit and so much tinkering. I am looking to get this camper dialed so that I can finally enjoy it. It has been working great on shore power or on an obnoxiously loud generator. I cannot seem to go boon docking with solely propane and battery though, which I was told was possible. So this weekend took it out and right away my Alde died and I had no heat- the light keeps blinking. I read in this forum that it has to do with lack of power which I have no idea how to check??? I read that I have to have some at least 10v of battery power which I should have had due to driving for 6 hours. Now thats another question...does my battery charge while driving? or only on shore power and generator? Next my refrigerator died that same night the heat went out. I had 4 more nights of camping and I was without a cooler or ice. I figured it was working because the green light stayed on but I found out soon that the green light truly means nothing. I attempted to start the fridge again and just heard clicking so I figured the ignitor went out...that was until I got home and tried it again and it worked right away. Now was it the battery? I tried the Alde again and was able to get heat but the red light kept blinking. What does this mean? Do I need to get a second battery? I checked the charge of this battery and it is good. Any advice as to diagnosing what is going on would be much appreciated before I attempt to take it to the RV service center. 

@sjanin, welcome. You have a lot of questions but you are in the right place to get help!

The issues you describe could all trace back to low battery voltage. The Alde and fridge both require 12V power to run their "brains" even if they are using 120V electricity or propane for their heat source. The trouble won't surface on shore power as your converter provides the needed 12V.

I didn't see any mention of the age/condition of your battery. If it came with the T@B and you are not familiar with how to assess its state of health, you may simply be dealing with a battery that is beyond its useful life. Fortunately--if that is the case--it's any easy and relatively cheap fix!

Also note that the battery switch must be ON (ie: not 'cutoff') in order to charge the battery, either via the seven pin or via shore power.

I agree, it sounds as though your tow vehicle was unable to keep your battery charged while driving, because of the fridge, so you ended up with a depleted battery when you arrived. BTDT! Sorry - frustrating.

The Alde red light will blink this error indication when your battery is too low (also when the propane is low, from what I recall).

Ice is your friend - we have a few frozen quart bottles in the fridge when we start out, as well as some in the cooler in the back of the truck. 

Keep at it, and keep asking!

@sjanin - Make sure you precool the frig on AC well in advance of travel.  Due to the high amp draw of the frig while on DC, some owners will tow with the frig on propane - which is controversial due to safety.  Another thing you can do is freeze water bottles and put them in the frig just before towing and leave the frig closed until arrival.  You can also put the frig on DC control for an hour or two then turn off for an hour or two and repeat.
