Stop in for a cup of coffee

Huh?
Remember what we did yesterday?
Take your finger and start at the source of power.
Do you recall that's the alternator we said was producing power at 14.2 Volts?
Follow the path to the main distribution point.

After you've done that, answer:
How does that differ than MAD's current flow path?
What I mean is that you now have two lines, one from alternator to the battery with a 14 fa fusible link, one to through the bulk head to the fuse block, then back to the starter relay via a 16 fa fusible link. Thus you're not having the full flow of the Alternator going through the bulk head, essentially splitting the load?
