ok so I pulled it out this afternoon and was this alt in the first two pics.
http://www.madelectrical.com/electricaltech/delcoremy.shtml I am assuming this was not the original as it doesn't look like a marine alt. and it seemed to be a rebuild.
I ordered this to replace.

I will definitely be adding a new wire from the alt. to the battery. I am assuming an 8 guage wire would be fine for this ? And do I still need to connect the orange wire back for it to work correctly ?
