i recently pulled the engine on my 1980 cx500 to remove a broken stud from the block. after replacing the engine everythings looks fine except the bike wont start. when i press the start button nothing happens. no sound, nothing. the headlights and turn signals seem to work just fine so i dont think the battery needs charging but im not sure. im not that knowledgable about wiring so if anyone has any ideas what the problem could be any help would be appreciated!
