HELP No power to jack, slides or awning
2015 forest river salem hemisphere lite 272RLIS
Getting ready to depart campsite and found that the jack has no power. On further inspection I found that the slides and awning also have no power. Checked breakers, blade fuses and high AMP fuses and all have continuity.
TIA

All the things you mentioned are 12 volt. Do your lights or any other 12 volt things work?
Are you on shore power or battery only?

On shore power. Agree they are all 12V items. Interior lighting is all working.

I turned the “perko” switch to see if perhaps the contacts were bad. No effect.
Can the listed devices run off the CONVERTER or do they need battery AMPS?

Do you have a multimeter that you could check battery voltage.
Maybe plug in your TV and see if it will supply power.
This really sounds like a fuse or a weak battery to me.

Load Tested the battery and it is putting out the correct 800 CCA.
I disconnected from shore power and still had 12V lighting so the 12V connection from battery to coach is good.
Got to believe it is a fuse or breaker issue. In-line or in the WFCO panel.
HELP :-(

There are no breakers on the 12 volt side, just fuses.
I know you load tested the battery, but all the items you mentioned have motors and draw a lot of power.
I'd double check those fuses.

Have you measured voltage at the jack?
Does the light on the jack come on?
Do the lights dim when you try to use the jack, slides, or awning?

So no 12volt circuit breakers like these, only fuses?
I always thought used them on high amp items.

Sorry I was loose with my jargon. There are indeed fuses. Blade fuses in the WFCO and there are high AMP fuses under the front of the trailer. I tested those and all have continuity.

Yes there are 2 high AMP fuses as in your picture. They have continuity across the poles and 12V at each pole. Yes

Yes, there should be a 12v resettable circuit breaker, with a tiny black reset button, tucked up along the A-frame.

Resetable Breaker Location
I replaced this resetable breaker with an automatic resetable one a few years back. There were actually two one was for the power jack which I eliminated as it also had an inline fuse as well. I have not had an issue since.

There are often inline fuses for tongue jack and awning. Everythinh else on 12 v will work but if these fuses are blown they won't. On my TT these fuses are in the wires up under the tongue.
Check around for them.

Testing for continuity is one thing. Have you tested them for 12V potential?
Do you have a remote control for your rig? If so, have you checked the fuses in the receiver?
