12V Power Supply Issue, could use a little assistance

When I am plugged into shore power I have full use of the RV (Wildcat 5th wheel 2013). including 12V lights and such.

However, if shore power is disconnected I have no power to anything....period.

I have replaced the battery with a new larger size deep cycle battery with no change in receiving power.

We are currently out and I have very little in the way of tools to work with.

I have checked my 12V fuses and every one is good from the looks of it. I have checked the inline fuses down in the battery compartment.

What am I over looking that would allow 12V power to flow through the RV when pulled into shore power, but allow no power from the battery alone?

Without the lone 12V batter power the frig will not power the LP side of the unit, nor do I have the ability to lower/raise the jacks should the need arise.

I appreciate your assistance,

Do you have a battery disconnect switch?
If so check that it is working and not stuck between on and off silly things happen and they do get bumped now and then.

Negative, Wildcat did not come with a battery disconnect switch. I have one that I installed on the old battery, but when I installed the new battery I did not transfer over the cut off switch just in case the new battery didn't solve the problem, I wanted one less item to trouble shoot.

Thank you for the suggestion,

To answer your question your convertor is supplying the 12 volt when you are plugged in. See if you have a tripped breaker at the battery. It's about 1" x 1/2" with a little black button that is the reset. Press it in and try then. It's on one of the ends on the bottom very small rectangular button.

I will go back and take another look, but I didn't see any breaker in line with the battery cable to where it attaches the distribution plate.

But that would sure make sense to be the cause of the problem.

Its a small breaker should be on the positive side, could be under the frame it is there somewhere. On a wildcat it probably on the wall in the front compartment. Your landing gear would be hooked to it also. Has two 1/4" post and nuts hooked to it probably 40 amp. might be attached to the wall like mine in a Rockwood.

Deal.....But, Would you mind sending your invoice directly to Forest River please? This should be a warranty covered issue I think.
LOL, we really do appreciate the help.
