Power Issues - Nothing works unless plugged into Shore Power

I have checked the converter. I have 120.0 volts coming in and 14.7 volts going out so I assumes the converter is ok. I have looked on the interweb and found alot of helpful information. However all the information I ahve found points to bad converters and it looks as thought mine may be ok. What am I missing.

Thanks,

The only thing that will work if not plugged into shore power would be the 12 volt ligjts unless your battery is dead. Sounds like that is your problem.

Sounds like the master fuse. From the positive terminal on the battery,trace the wire down to the frame. There is a small fuse, usually hidden in a black "waterproof" holder right next to a junction box.

X2, sounds like a fuse issue. There should be a independent fuse very close to the battery, on the positive terminal. It will looks something like this one.

Pop the cover and check the fuse. It should be a green 30 amp fuse. Some people have replaced them with a circuit breaker version.

What 5ver do you have?

Definitely sounds like a fuse but if itís trying to charge at 14.7, thatís the max a multi stage charger will put out if it thinks the batteries are low. If itís recognizing a low battery, maybe it is a dead battery.
Need battery voltages to give more help when not plugged into shore power, check at the batteries and also at one of the fuses in the converter/breaker box.

This is the fuse and holder on my travel trailer. I pulled it down and snapped a couple of pics for you. It should look similar to this.

Wow you guys are awesome. I keep the batteries on a trickle charger in the garage and took it out and connected it yesterday. I checked this morning and the Voltage is 13.2.

I am going to look for a fuse right now.

Again thanks for the help. You all Rock!

Now for your next problem. What caused the fuse to blow?

That yellow fuse is a 20 amp. If you pulled it from the battery it should be a green 30 amp fuse.

It would not surprise me that you blow a 20 amp fuse, while moving a slid out, or power lift system.

Might even popped it when putting the battery back in.

I keep a pack in the tool box at all times.
