65 electrical system

I'm still working on my protecting my 65's electrical system from damage. My questions for the experts are:

Has anyone measured the amperage between the start switch and the starter during actual starting of the engine?

Measured the amperage between the positive side of the battery and the starter during actual starting?

Measured the amperage between the starter and the alternator with engine running?

A "tight" engine can pull over 350 amps during cranking (hence the large cables between battery and starter lug). And the alternator will deliver the rated value at an engine speed of 1500 rpm or higher ( in good working condition).

The area that needs protecting (and had none until 1967) is the 10-ga. red main power feed wire from the battery cable stud on the starter solenoid that feeds the whole rest of the car; it needs a 14-ga. fusible link spliced on it where it connects to the stud on the starter. Any good auto parts store has them, with the correct large ring terminal already on it.
