questions about battery disconnect wiring

WHAT SOME GUYS DO Some guys like to run the alternator output to the battery direct. This makes the disconnect "work" but IT STILL LEAVES a nice big wire "hot" all the way up to the alternator. I like to claim this does not meet the intent of the rules, NOR IS IT SAFE. If I am the guy, upside down, with fuel dribbling everywhere, I would rather not have that alternator wire "hot"
