Essential power came off which generator the FE selected, except for the TWA config where, guess any pilot could select it. But no auto-switching, if STBY wasn't selected and 3 gens out--no flight instruments! I was always taught never to go with #3 gen inop--if you lost #1 and #2 engines there would be no way to power the standby hyd pump and no rudder.
At a recurrent a captain asked why he got a fire bell, they silenced before they could identify the light in the handle. The FEs in the back row snickered while the instructor mumbled something like he'd never heard of that happening.
Westie. It was designed on the B727 as an afterthought. Boeing mounted in the right wheel well, so no airflow for cooling.
