Apparently they have been listening as losing market share does get your attention. It weighs much more than the original and is listed as a 33si. Has a plastic fan and a ground lug. Now planning to run a number 4 direct to battery or starter and a number 9 to main fuse. Your comments advice recommendations and possible castrations are welcome.

I have a 140 amp alt. I run a #4 straight to the battery and use an inline 200A breaker. I have an old electric winch and onboard compressor. I have potential for pretty massive power draw, I use #4 ground wires also. But for you, over kill on the big #4 can't hurt... as long as you have your hands on it and you can keep the #4 out of the way. I lug and slug all the connections and use mil spec battery terminals.
