INTERAV alternator kit 015-01237 12v 50amp

[ed]

Selling used alternator setup removed from m20C O360 wide deck.  It was working when removed Oct 2016.  Replaced it because CB had tripped twice in two months or so.  Finally found the issue when it was all being removed, there was an unshielded ground wire under panel that sometimes vibrated over and caused a short.  Was not the fault of any of the parts, but had already purchased replacement system so installed it.
