I'm new to the forum but have been reading lots of posts and getting ideas for several weeks now. Diving in with the addition of a radio and winch so I will be installing a second battery this weekend and a switch plate. I will be using a True isolator, circuit breaker, and stinger relay, along with a 6 circuit fuse block for accessories. My question is this, my radio has an inline 40amp fuse which I will leave alone and attach to the stinger. Are there any issues if I still attached the ground wire from the radio to my fuse block?
