If you open the alternator output breaker while the alternator is
generating power then you get what is known as a "Load Dump".

So, Based on this (and the rest of the info in your post), it sounds like it
would be perfectly ok to start the aircraft with the alternator out of the
circuit. I'm not sure it would be a good idea to cut one out in a twin. Does
this load dump occur if there are two alternators feeding the system and you
cut one out?

To a pilot, altitude is like money - it is possible that having too much
could prove embarassing, but having too little is always fatal.
