    20A03533-4754-448E-AB08-682770BDFF93.jpeg Must be a broken wire.
    The alternator output is routed to the starter terminals where it hooks onto the same heavy gauge wire that connects the starter to the batteries.
    There is a Alt Remote Sense 5 amp fuse located on the firewall, on the drivers side. Though usually it causes an over voltage if this fuse is blown
