I already installed an isolation switch up front on my chassis battery system and today I started doing the same thing to the house battery.
My house battery is located in the battery compartment next to the Onan. My plan was to install the switch into the negative side.
As I was marking out the bolt positions for the shut-off isolation switch I realized there are TWO negative lines attached to the battery, guessing the one leading away must be the line that connects to the systems up forward while the other runs to a ground bolt close to the battery.
Even as an electrical ignoramus it seems to me that installing the switch into the ground connection line close to the battery is not going to shut off the battery completely as the other negative line would apparently still be able to connect to ground, right?
So do I have to run both negative cables to the switch to shut down the house system?
