electrical non-lbc problem

Seems my neighbor was on his way home on his Honda 750 motorcycle (Shadow?)
when his throttle stuck. Bike reved & reved and would not shut off. It
eventually did stop. (suddenly he thinks) Inspection shows a throttle cable
came loose but now the bike won't even turn over. I think he burned
something electric as a result of the high revs? Any suggestions? Where
would one start to look?
TIA
