I think it may be worth redrawing your diagram more carefully and fully.   

I don't see where your loads (fridge, lights, water pump etc) are connected in that diagram?  Where is the fuse block you show in the picture?

 

Yes, you should just go from the ACR to the battery.   For now I would ignore the load terminals on the Victron MPPT until you get things sorted out.  

 

But first, a better diagram!  The process of making this will likely lead you to the solution without any help from us.

Making a new diagram. Will get back Wednesday (tomorrow).

Leonardo I am not. Attached find a 'sketch' diagram with how I think I should wire it. (note there two lines with inline fuses...) those two,  red and black with fuses are what I had going into LOAD. (duh). Is this now correct?

 

The other question I have is the ACR switch. Where should it be for the usual usage? Engaged?  I know these sound like elementary questions but at this point I'm questioning everything. I have a photo for how it was connected with the AGM (there were two and the extra black and red are from the 2nd battery in parallel as well as two small controllers (now replaced with Victron 100-20).

 

Really appreciate your input.

Much better digram.   To be clear - the diagram is not the way it is wired now, but how you think it should be wired?  I am also a little confused about the photo - I thought you were using a Victron MPPT solar controller?

 

Anyway, there are a couple of issues with the diagram - read up a little on how an ACR should be wired:

One terminal of the ACR should connect to your truck alternator/battery and the other to your camper battery.   You also want to connect your Iota Fuse box (white) to your house battery positive.

The photo is of how it was when I had AGM. The diagram is how I think it should be wired now. Is this diagram correct? As the diagram shows the ACR would be connected to camper battery on same terminal as white to truck. The other terminal goes to camper Iota fuses

No, the diagram is not correct - the camper battery should be on one terminal of the ACR and the truck battery should be on the other.   The Iota fuse panel should be connected to the camper battery.   Do you have the FWC pull out switch in your camper?  If so you should add that to your diagram as well.

agreed.

Correct... my diagram is wrong. The white wire to the truck battery goes to the ACR post.  The other post on ACR goes to the Iota. (That white wire goes back to the pull knob first and then on to the Iota). 

NEW DIAGRAM BELOW.

 

Bear with me here..... on that ACR post with the Iota white wire there is a red (with the inline fuse to the positive house battery). Effectively connecting the Iota main with the battery via the ACR post. (that is the way the camper came).

 

The camper is not currently on the Truck.

I rewired it as seen in the corrected diagram. 

I started the Fantastic fan on high.... 

I turned on fridge.... and the fan died.

 

I removed the Victron Controller and reinstalled the 20L Sunsaver controller.

I turned on the fan on high

Turned on the fridge .... all was well

 

Do I have a bad Victron

Can I test it??

Are you still connected through the load terminals on the Victron?  I am not sure how else it could be switching off the power to your fan and fridge.

[buckland]

As the diagram shows there is nothing attached to LOAD on the Victron. Is my diagram okay as to you’re last question about ACR?

Just a thought..... a fault with Fridge wiring?
