Anything with a modern transistor / diode junction & this includes the
alternator.

You could wire the alternator output to a set of three 5U4 vacuum tube
diodes..... And what's scary part is I know how.

Back in the Korean war (ok, conflict), a Soviet MIG "jumped ship" to the
American side. Our Engineers laughed at the vacuum tube technology until
they realized the technology was not affected by EMP pulses. These days
military hardware is "hardened" to withstand EMP pulses.

I'm not very knowledgeable here.  Given that, I'd expect ECU, idle stab,
tach, ignition module on a 1.9l, DOPS board, Westy LED panel, GPS, computer,
stereo, transistor-driven LEDs, maybe all LEDs, maybe ignition coil, maybe
alternator.  Depending on strength, maybe other stuff.  Best protection - be
somewhere else.

If you want to run after an EMP, I suspect your best bet is an old-fashioned
mechanical-injection hand-cranked diesel.  And don't have a pacemaker or
defibrillator installed.

Yours,
David
