2008 Eagle Electric Issue

[Vikinghb]

My 5th wheel will not run off the battery power. Checked battery with meter, and It's reading 13 volts without having it plugged in. Once plugged the meter runs 12.5 to 13. No issues with running plug in power.for everything in the trailer.There is a fuse by the battery, and it is fine.
One strange thing is if I turn on one of the light switches, I get this buzzing noise from under the fridge, and once I turn it off it stops. I looked through the fridge vent under the unit, and could not see the converter.
Anyone know where the converter is in this unit?
Do you believe my problem is the converter?

You say the battery fuse is fine. Did you check it with a meter? It can have a crack and look good but not work. Also is there a second black battery wire in the battery compartment that is not connected?

The fuse is fine, I checked the resistance with the multimeter.
The black wires are all connected. Buzzing noise heard was the 02 detector, and it's strange it will only go on if I turn a light on.
Still would like to know where the converter is without tearing everything out.
There might be another fuse.

I think it is suspect. If no one chimes in here, Jayco Cust service may be able to help you.

There should be a power panel looks something like this

outside


inside


I found a link to troubleshoot when you do find it, just in case you need help.

One thing I forgot to mention is when I am on shore power the DC run things such as lights etc work fine. As soon as I unplug they do not work, and the the detector starts to buzz.

Looks like the converter is not re-connecting the battery to the RV's 12V system.


Check all the fuses and connections from the converter to the battery. Especially the ground (white wire) from the chassis to the battery negative side.






After that, its a relay in the converter.

Found the problem, it was a fuse further down the line. No extra spend for a converter, ALRIGHT.
