The other disappears into a wiring harness so I suspect that it is mislabeled.



So the question of the hour for the other Thor owners is this: if you also have four leads (i.e. battery cables with ends that attach to posts) in your battery compartment, how many are connected to the positive terminals and how many are connected to the negative ones? Do you know what the leads are for (e.g. one to the inverter, one to the emergency start switch for the chassis, one for accessories, etc.)? When I say four leads, I am excluding any jumper wires that are used to connect the positive terminals to the other positive terminals in a 12V parallel configuration. I'm talking about four leads that eminate from the coach into the battery compartment.



Hot on the trail - thanks for the help! I really wish Thor had wiring diagrams....



Thanks,

You might find a wiring diagram on Thor Motorcoach Owners Resource site. Need your VIN... 2014 and newer.
There will be multiple leads.. including negative/ground. Ground wires run throughout the coach. doesn’t rely on chassis (which isn’t accessible in cabinets, etc... and several high current loads.
While there can be junctions in battery compartment as well, I would expect separate lead to jacks, inverter, and coach loads (goes to use/store.. emergency start switch, etc) at minimum.
Following wiring, the positive should pass thru 100 amp or so resettable breakers.
