I am about to wire my Orion dc charger in my bus. The bus starter battery (under the hood) is wired to an auxiliary battery about about 1/2 way down the bus. Only the positive cables are wired battery top battery, the negative cables are both grounded to the frame.
I would like to wire the Orion to the auxiliary battery as it is a much shorter run and clearer path for the wires. Both the main starter battery and the auxiliary battery are the same model.
Is there any negative going this route?
Thanks for any advice/insights,
Dylan
