I ordered a 140 amp Tuff Stuff alternator, (made in the US). They told it should be fine in the 153 as long as I run a #6 charging wire and #10 ground. They also told me that it can be set up as a one wire. or three wire, but that for my use the 3 wire setup would likely be preferred as it will excite as low as 800 rpm with the 3 wire set up. I'm running #2 wires for the winch to both ends of the jeep through a marine battery switch so they won't be hot until I need them. I set the winch up on a Reese type mount so I can use it on whichever end makes sense at the time. I still have some thinking to do about whether to ground through the frame, or run ground wires to both ends from the block ground. And whether and how to fuse any of this stuff.
