I have a 2011 jay feather. When hooked up to electric power everything works fine, but when I disconnect the power I try to run from my battery I have nothing. I have checked all the fuses including the two fuses on the lines that connect to the positive and negative. On the battery lines, one has a black wire and the other has a black and white wire, pretty sure the black and white is negative and the black one is positive, when hooked up to electric when I touch the terminals to the battery post they will spark but no sparks when electric is unplugged. Are they a battery connector switch somewhere on the camper?

Jay Feathers have a fuse at the Battery + also if you have a PTJack there should be a 30 amp fuse for that. If the battery doesn't feed power to your trailer the problem can be at the reverse fuse or the Batt. + fuse. The reverse fuse on WOF converter is on the panel and Progressive Converter is on the converter it self.

Following this because same issue popped up with our trailer during packdown last weekend. Battery checks out fine. Hubs will recheck the reverse fuse again. Hoping that will be the problem & an easy fix

Good thing is if that is not the solution, we still have 2 months of warranty. But that will require the usual weeks of trailer at dealer & cancelling 1 camp weekend .

Thanks to all the knowledge that is on this forum!!!!

Have you checked the ground wire from your battery. Make sure that you have a good ground connection.

There are items like the propane gas alarm and the radio's clock that create "phantom" drains on your battery. I know that after a week or two of just sitting without shore power to keep the battery charged, my battery has lost a good bit of its charge. I would recommend disconnecting the battery if the coach is going to sit without being on shore power any longer than two weeks.

Another phantom drain is the television antenna's amplifier if it's accidentally left on.

You need to get a multimeter and just check your wiring for continuity starting at your battery.
The 30amp "fuse" is usually an auto reset breaker not a fuse so you will have to check it with a multimeter.
One other thought is that maybe you have the positive and negative backwards on the battery as the colors are not intuitive. Just follow the cable attached to the frame it should go back to the negative terminal of the battery.

Another check which is often overlooked. Fuses at the converter. Many converters have fuses which are NOT part of the fuse panel/circuit board/circuit breaker. In order to find out, you have to remove the circuitbreaker/fuse panel itself. Pull it free and look in behind it at the converter itself. You may need a small flashlight and/or small inspection mirror. It is surprising how many people never check for this. Meanwhile an RV shop gets to charge an hours labor to change one or two fuses.

As for your refrigerator, turn it off of shore power and run it on propane for a while and see if that makes it cool more/faster. Though unlikely, the electrical issue could be related to the refrigerator no cooling properly.

10 dollar multimeter and you could quickly determine if your power panel, with all the 12 volt fuses is getting any power at all. If no, at least you know the problem is upstream. Is your smoke detector still working? If you are sure your battery is good, you either have a bad ground connection from the battery to the frame, or you have a blown fuse between you battery and your 'fuse box'. Troubleshooting electrical issues on any of these campers can be time consuming, but if you take your time and test some key areas with your multi meter, it's usually pretty easy to determine where the problem is.

Thanks for all of the good info on this. Luckily husband is electrically inclined. Battery tests fine with meter and ground wire has good connection. Will be re-checking the reverse fuses and pulling out the panel to check for the additional fuses this week.

Will update & share when we find the root issue.
