Here it is 3 am , I awake to a humming noise then out goes the power, directly things come back on. I have noticed these past few days at random times that my lights seem to flicker a bit, can someone please give a bit of advice for I know taking this thing to the shop is like dancing on hot coals then you have a 5 k bill and still no resolution to the problem. This is a 2004 Big Sky Montana fifth wheel, any and all help will be appreciated.

Well you should post this in the tech forum as opposed to the hybrid but first off what is running at the time? Do you have hookups? Can you tell where the humming is coming from? Could be the air if it's on, maybe the converter if nothing else is on, transformers and fans can hum when they go south. Oh ya, welcome, if you're still with us.

Sounds like an Electrical Management System may be in order.

Ok at 3am not much could have been running, an a.c unit refrigerator, maybe hot water heater and tv with satellite receiver, every time the power shuts off that propane detector starts beeping REALLY loud then goes off. The humming noise seems to come from the converter area. After the power shut off and came on about 10 different times finally at 6:30 this morning it came on and has not went back off. It seems that this only happens late at night or early morning......I just got here with my husband he says that it just random has been doing this for about 3 weeks now. Any ideas now?

Have you been at the same place for 3 weeks now? Might be the incoming power is sagging. I can't the converter or AC caring if it's night or day, they would do it at all times of day if you have the same load on. The management system mentioned above may be a good idea. This is what one looks like, and Here's a good write-up on the electrical system.

There can be many reasons for power to go on and off mostly because of faulty equipment or parts of equipment .Any "ideas" you get from here based on the info you supplied will be just that - ideas. Do you really want to spend money for parts based on that ?Get a cheap simple multimeter and read the manual and do some investigating into what exactly is going on .Are you loosing the park AC input or just the DC output from your converter ?Some very sharp folks read this forum and with some facts could certainly advise you .Good Luck, Mike

You may not have one. Here is what it looks like.

You have your answer from the park !
One might remind them if they KNOW there is a problem and that on/off destroys your AC or converter your insurance co will look to them to repay them after they cough up $1000 to have someone come out and replace for instance the AC unit. You sure would hate to see them get in hot water when they had the parts all along :)
Good Luck, Mike

Ok we talked to park personnel explained what was happening, he said and I quote"oh yea I forgot there is a bad hub there I have the parts to fix but just never got to it" now as for being able to move there are no more sites available here or anywhere close to here, now after getting ths information from the park I felt a bit of relief thinking it was going to be fixed TODAY. Well here it is at 2:20 am and we lost all power this time to everything except the ac unit upstairs, thinking I am going to look for this self resetting breaker in this thing.

The battery on here is a brand new battery we just put on here two weeks ago thinking that could have been the issue, my guess now is not.

It may be a self resetting circuit breaker that is failing. I had one in the line between the battery and the converter. It was a 40A breaker but it started opening at about 15A. It would open, everything would go dark, then self reset a few seconds later and the lights would come back on. Replaced the breaker and all was well.

I beleive DR Quick has hit the nail on the head. It is a incoming power issue and I would have the park personnel check the post real quick. If it is ok then a call to a mobile maintenance man is in order. Hope fully the park office can recommend a good one. This issue sounds like it is beyond your capabilities.

Has anyone checked the battery lately? A lot of your 120v devices need 12v to the circuit boards, including the alarms. If an intermittent 120v "brown out" occurs, the converter and battery should allow for 12v power to be available. It sounds to me like you have a bad battery and the converter is failing, trying to charge the bad battery.

Just curious if anyone in the area is having problems too. If you have a 50 amp extension chord, could you connect to an adjacent open site for a few days? Or have you asked to move to another site? If this would stop power interruptions then you know problem is not in your trailer.

The catch is it doesn't do it every night nor does it do this all the time the 4th was the first for me and it happened about 11:30 am then again about 6 am Friday morning then again this morning several times........

Just at a loss for why this is happening
