Need to figure out which is connected to GND (it should connect to on B2 or on B4.
The other two would go to + on B1 or + on B3
I was wondering about that....is that a ground that C1 is connected to? Looks like it, but things aren't always as they seem!

Sure is getting good now, if there has not been no "sparks" as of yet.........there might be soon
Might want to un-plug your ECM &TCM till you figure this out.......

Here's a diagram I drew up showing what you have now (apologize for the chicken scratches):

As has been mentioned C8 seems to be in the wrong place.

I would suggest you contact Fleetwood customer service and register (if you have not already). When you do this you should ask for a wiring diagram for YOUR coach. They should be able to send it via email. I just did this in November for my "new" coach, and received numerous files including the wiring diagram. It is very detailed, and should answer any questions as to how the wires should be connected.

I also would suggest a possible issue with corroded/dirty cables. While helping close down a campground for the winter a couple of months ago, I had occasion to clean up a couple of golf carts. When checking the battery condition I noticed that one cart had a lot of corrosion and build up on the cables and terminals. I removed them all and cleaned them thoroughly, added a little dielectric grease, and put them back together. I was told later that week that the cart no longer needed to be charged each night. Apparently it wasn't getting a full charge before the cleaning.

Here what I think it should look like:

C8 should be between the neg post of B2 & B4.

MoeBelly, That is exactly what I described for him to do. I have never had very good luck with fleetwood helping out much with electrical.

Yeah, you beat me to it.

I was too busy trying to get the attachment thing working on my iPad.

Hi 4tfamily,
The cables connecting the batteries look okay.
C7 & C9 make the four 6 VDC into 2 12 VDC batteries (in series).
C6 & C8 connect the 2 12 VDC battery banks together (in parallel). C8 could go to B2 - and B4 -.

If there is a problem with the wiring it is with the wires that go off into coach land.
C1/C2 & C4 better be attached to a positive something in the coach.
C3 & C5 better be attached to a negative something in the coach (ground).

The disturbing thing about the OP is that it mentions the problem was solved then came back. If the problem is wiring, it should be a hard failure.

You're going to need to ensure the wires going into the coach are really positive or negative. Also which wires come from the converter (charger) and which go to power the coach 12 VDC/inverter and anything else.

I am in agreement with whoever posted the picture makes one's head hurt.

FWIW, and it's hard to tell from all the corrosion, that "block" between C1 and C2 looks like a shunt used to measure current. If so there should be a twisted pair of small wires going from each post to a battery monitor. But a shunt normally should be on the ground side, not the +12 side of things.

The block between C1&2 is a high amp fuse and it probably goes to the inverter. I haven't seen a shunt of that style used on a coach in years.

MoeBellly has it right IMHO. What confuses the issue here is the twin sets of feeders, ostensibly to uprate the current carrying capacity. It would be better to eliminate C2 and C5 and upsize the conducters.

That "extra" set of cables (C2 & C5) are probably dedicated + and ground for the inverter and the other set of wires go to the main relay and ground in the chasis battery compartment.
