Alternator Upgrade
**disclaimer: I learned everything I know about this from the internet
I picked up a Powermaster alternator and a “Full Power” kit from Mad Enterprises
http://www.madelectrical.com/ about 3 years ago, and then we had a kid. And then another one. And now I finally got around to putting the alternator on. And now we have another kid on the way. Anybody got a suburban they wanna sell me?
Before we go any further, a few threads I couldn’t have done this without:

The Powermaster alternator is not exactly a direct in-kind replacement for a few reasons. First, the old alternator harness plug is not the same shape as the plug on the Powermaster alternator. Second, I was looking to upgrade a few components of the charging and electrical system and install an auxiliary fuse panel while I am getting into it.
The new alternator is a Powermaster unit, part number 47294 advertised output is 90A at idle and 150A max. The “Proof of Performance” tag included with my alternator says it dynoed 99A at ide and 164A max.
