In the install manual it says to run a ground from the battery to the frame and from the ground screw on generator to the frame. I have a 2017 Torque 325 with generator prep package. Has everything there I was just curious if I could run the ground from the generator back to the ground on battery. Also is the battery already grounded to the frame so I don’t have to run another lead. Thanks in advance. About ready to fire it up.
