Let's start with "no juice whatsoever".
That points to the battery being defective or not connected - have you tested the battery?
Did you by any chance connect it backwards when putting it back in?
Samurais have a fusible link that may blow if you do that, causingthe symptoms you are having.
Get a meter or a test light and start troubleshooting - do you have 12V at the battery? at the alternator output lug?
