But it does need the alternator to run the electrical equipment such as 
lights, radios, heat and AC fans, etc.

That is the description of a classical alternator failure. The alternator 
failed but the battery continued to supply electricity to the bike until it 
was exhausted. Once that happened, there was no electrical source, and the 
engine ceased to operate. If the battery alone goes dead, the engine will 
continue to operate from the alternator-produced electrons. The jump start 
gets the engine started, the alternator then produces electrical power to 
operate electrical equipment and to recharge the battery.
