The diode bridge inside the average alternator is robust enough to snub and dissipate the starter energy provided the alternator "A" lead is intact and on line across the bus.
From my perspective Nuckolls is a new guy. He didn't start monkeying with this stuff 'till Cessna had begun using alternators, so he is not well placed to be the last word on this subject.
Let me describe the sequence involving a starter that has the potential to damage electronic stuff:
1. The Master is turned on, connecting the battery to the bus.
2. The starter button is pushed, energizing the starter solenoid
3. The starter solenoid connects the starter to the bus.
4. several hundred amps flow to the starter and the starter begins to spin the engine.
5. Battery is low, so starter slows and and stalls.
6. the stalled starter with a hundreds of amps demand pulls the bus voltage down to a few volts.
7. Master solenoid drops out , disconnecting battery from bus.
8. the very strong magnetic field of the starter collapses (the starer now is just a massive inductor of copper and iron)
9. A very high energy spike WILL BE produced if there is nothing to snub and dissipate it.
The above is not the normal start sequence. Normally, the STARTER solenoid releases first,turning the starter off and the starter energy is dissipated on the solenoid copper contacts.
BTW, proof by authority is not a good way to argue, but I DO have an A&P, accessories, radio, instrument repairman certs, had a repair station for a decade and stick wise most everything but an ATP. And way back when I worked for a living I was an Electrical Engineer doing mostly military and computer design stuff.
Nuckolls has done some really good stuff and I tip my hat to him, but I can demo blowing a small diode out with a starter spike any old time.
I think that having to start a dark airplane is too restrictive, too old timey. Protection should be standard so strobes, radios, EFIS, EMS audio amps can be on with no fear of damage from any cause. Stay tuned.
