Smallish Wireing

[Jim Hingston]

I have a 2012 295rlds Jauco Eagle. We like our trailer so far. Have been on many a trip.Does every Jayco have 10 gage wire from the battires to the charger? seens small, We have 2 6 volt battires as we boomdock a lot.

We have 10 gauge as well. I restore antique cars for a living, and deal a lot with 6 volt systems. The main reason you see very large battery cables in 6V cars is for the current required to crank the engine with a 6V starter. The main wire feeding all the rest of the electric items is usually 10 gauge. That should be adequate for wires from the AC converter to the battery, IMHO.

Here is the kicker. When I was running in the cables for the solar panel on the roof of the TT, I noticed that the NEGATIVE cable that runs from the battery controller to the battery, is a white 8AWG cable while the POSITIVE (+) cable is a 10AWG cable.. I am looking at changing the 10AWG (+) cable to an 8 or both to 6 AWG cable. For best battery performance, both cables need to be as close as possible in length/gauge between battery and load (EQUILIZES CIRCUIT RESISTANCE). Hopefully I should be able to use the existing 10 gauge as a fish for the new 8 or 6 gauge cables. This has been on my upgrade list for about 6 months now, but DW has a different list than I do.......

Mustang65, if you track your ground cable you will probably notice that it is only 4 or so feet long total, and connects to the frame. All the 12vdc functions are grounded to the frame somewhere close to the item.

I just crawled under the TT to verify. The 2013 Eagle 284BHS has the white 8 gauge from the battery (-) that goes into the 4x4 electrical wire distribution box on the frame (near the batteries) where it then goes into the underside of the TT and it does go back to the battery controller. There is also a short white 6 gauge cable that goes to the frame from the battery. That is what caught my eye originally.
