I have my battery and tray out to replace the sway bar mount. I was looking at my ground cable and the connection that is screwed in by the hood hinge was green! It didn't look to healthy so I decided to replace it. I went down to the boat yard and bought some tinned 2/0 ground cable with a tinned battery end and a tinned loop end. After a little soldering, crimping, and some heat shrinking I now have a heavy duty ground cable that is 10 times better then the original MB one. Cost me about $12, I used quality Ancor stuff too.
