No Battery Power.... Please Help

[Crop Duster]

So we were suppose to head for a trip to Canada tonight and pulled the camper into the street to finish packing it. Well come to find out I don't have any battery power in the camper. When plugged into shore power everything works (fridge, outlets, lights, microwave, etc...). I have a Trimetric 2030 hooked to the batteries and they are at a full charge.

I have power to the front and rear of the breaker that is connected to the frame on the front. I also have full power to both wires on the back of the factory battery disconnect switch. I'm at a loss.... Four days ago I had it in the street doing some maintenance and everything worked fine. Where else should I be looking?

I assume the 12 volt fuses have been checked?

[Crop Duster]

Yeah all the fuses have been checked including the main. If a fuse was blown would that particular item still work on shore power?

Check the resettable fuse along the A-frame.
Press the tiny black reset button.

I've checked that breaker on the frame and the black button is pushed in. I also have 12v power on the top side which is the cable running into the camper.

Check at the converter next

[Crop Duster]

Seems like I don't have power at the converter when on battery power. The red wire is hardly reading anything.

[bob caldwell]

Pinched wire....

For a quick fix, string a new one till you have more time.....

Okay now to add to the confusion. This entire time my Trimetric has been reading 12.9V even though I'm plugged into shore power. I don't know why it's been reading low but I didn't pay too much attention to it (I just installed it 2 days ago and I'm getting used to having it and what the numbers can mean). Well I just went out to the camper to check more wires and noticed when I walked into the camper the Trimetric was reading 13.6V (which is what it normally reads when it's charging). So I thought what the hell, I'll just unplug from the shore power and see what happens. Well everything works now. I haven't done a dang thing. What is going on?

[bob caldwell]

That checked the wire as being good, so I'd say the converter might have a bad or loose connection

This trailer has a Progressive hard wired unit, but the numbers are the same......edited last post

Just throwing my 2 cents in but I had the same issue and had to call a tech in. Was on a fiver and over a period of about 6 months, had no battery power. Long story short ended up a factory issue where all the connections from stem to stern on the 12v side needed tightening. Even behind the fuse panel. There as also a breaker under the exterior back and the contacts were loose there also. $500 later in labour, everything worked great. Hope this isn't your problem but check the contact connections.

Could someone watch a light when nothing is working and could you wiggle wires till the light burns? Then wiggle till the light doesn't burn make the problem come and go. Narrow it down and find what might be a loose connection.

Self reseting breaker. Mine is near the battery switch.

[Evereddie]

Battery disconnect switch? Do you have one?

[bob caldwell]

Yep

Well it seems to be working for now. We're on the road with it but before we left I was able to find some loose nuts on the wiring for the breakers on the tongue of the trailer directly after the batteries. I don't think that was the problem since I had power to the battery disconnect switch which is inside the trailer. But I'm keeping my fingers crossed that maybe it fixed itself.
