Power Out

Just got back from our first weekend out this year with no problems. I get back home and can barely get unhitched even with shore power. Batteries are dead and no electrical even though plugged in at the house. Any ideas?

It won’t even work plugged into your pickup?

There is not enough info to answer. You need to tell what rig, model, year, and in this case, what batteries and anything else that can be related to your problem.
Without any of this info, it is very possible that your battery bypass switch is turned off, which would cause your batteries to not be charged, as your converter, which is what makes 12 volts DC out of 120 volts AC, needs to be connected to your batteries to get them charged. If the red switch in your convenience center is off, and this is when the key can be removed from the switch, your batteries are not connected. It is possible that you went all weekend running on batteries and they are now dead, and even when connected to shore power, the power from the converter is not enough to operate the jacks. You must have fully charged batteries, or very close to fully charged to get the jacks and leveling system to work.

Still no 120 volt power

The unit is a 2015 353RL High Country.

The battery disconnect is on and was not off. I have charged the batteries and have 12 volt power. I have checked all breakers in the panel and everything is good. I have pulled the panel in the basement to get to the converter and checked the fuses, all good.

Any other ideas?

Check your 7 pin connector, possibly blew the fuse in your truck and it is not charging when hooked to truck.

Can you pull the key out of the battery disconnect switch? There is always confusion on which is the disconnect position, if you can pull the key out, your battery is disconnected. On meaning that the disconnect is ON and the battery is disconnected. Just a thought.

IF all the 12volt is dead in the coach. Before you do anything else follow Bob's advice and check the battery isolation switch. You will have to give the inverter a while to recharge the batteries. To get around that you could use jumper cables from your truck to test to see if it is actually a weak battery issue. Bob is right the inverter is by no means strong enough to power the jacks alone you need the batteries charged.


IF only the jacks are not operating: Hook up your jumper cables (make darn sure your battery cables are good) from the truck to the power leads for the jacks and see if they operate normally. It is fairly common for landing gear to get bent or not have enough grease or the motor to get weak etc....

I'm not the best at explaining things sometimes, however, the problem is not with the batteries, I do not have 120 volt power in the RV.

All was fine last weekend at the lake, got home on Sunday last week and I have no 120 volt power.

You need to check your power cord first if it is good then check the the plug in in the back of the trailer I have seen them come apart inside if it hasn't then start checking the rest of the way up to the breaker panel. make sure you use a volt meter

Ditto to Bob. You threw us off with the couldn’t unhitch comment. The landing gear are 12 volt.

A volt meter is a must have tool for an RV owner. It allows you to start at the power source and work your way downstream fairly quickly and isolate your problem.

Since your entire coach is dead it is most likely one of the issues Bob mentioned or it could be the plugs themselves. Those plugs have a lot of high amp juice on them and can overheat and or arc over time. Need to inspect them often.

I finally got some time this afternoon do a little more digging in to the source of my lack of 120 volt. After a quick trip to Home Depot to purchase a Non Contact AC detector, I found that my 50 amp to 30 amp adapter cord was defective. Really strange how it worked one day and not the next.

Problem solved! I had an extra adapter in the RV and quickly had 120 volt power to the Montana.
