03batt.jpg He has the battery going to the starter relay (correct), but then ALL the vehicle power goes thru a 30A (pitiful) maxifuse inside that black rubber housing, thru a loop to the ammeter in the cluster, then back out to an isolation lug with the alternator & all the fusible links.  So the meter marked "ALT" is actually showing the BATTERY's current to & from the vehicle (other than the starter).  If the battery was ever run down, & the engine was started, OR if a lot of electrical loads were turned on with the engine off, it would burn out a 30A fuse easily, for no good reason.  I'm swapping in the largest one I can find (a 60A) to allow the ~90A alternator to do what it's built for.
