    3.0 lost all power!

    that 90A block originally was to protect the alt and wiring, merc added the Red main system power to it for whatever reason. Why have a 50A after a 90A . I modify the wiring by adding the system power wire "Red" directly to the battery post and use a Maxi-Fuse crimped to the alt feed "Orange"...
