Battery cable grounding for Thor Chateau
For the 2013 Thor Chateau 24C, what is the house battery cable grounding? Is it a positive ground or negative ground arrangement?
On my coach, there is a longer, black, cable that appears to come from the interior (converter) area and a shorter, red, cable that is attached to the chassis.
The longer, black, cable is attached to the Negative battery terminal. The shorter, red, cable is attached to the Positive battery terminal. As connected the outdoor light will light.
Is this the correct cable to battery terminal connection?
