Needing some electrical experts advice here (since I am definitely not one!). I would like to install a battery disconnect switch, but don't want the common type that attaches to the battery itself, since my battery resides under my seat. I'd prefer to extend the negative wire going to my battery, run it to a convenient spot, and install a toggle switch inline. Anyone done anything like this? What kind of rating(s) would I be needing for such a switch? Any (pardon the pun) negatives to watch out for? Thanks in advance.
