(adding) And generally effective.
I haven’t had starter cable problems, but I don’t deny them.
The routing of the headlight power circuit to the dash and back to the headlights was inferior to their later use of relays in the engine bay for that circuit.
the path from starter to battery be thick enough to carry the starter's amperage draw.
Yup… heavy cable from BAT to engine for both positive (to starter) and neg (to block).
Large wire from ALT POS output directly to BAT (alternative: to starter stud). ALT NEG output path to BAT is via engine block and same heavy NEG connection that was required by starter.
One (1) solitary “star” GND connection for engine & frame & firewall (this is typically made either at the frame or at a firewall stud, sometimes at engine).
No multiple GND paths.
We can now talk about how the loads are / should be connected, if anyone’s feeling chatty
But that’s off topic for this thread.
