My 1st post/thread thingy _I have 2 -2002 Montero Sports,1)2 wheel drive,recently deceased,2nd 4 wheel drive,died about 6mon. ago, Issue : no power,no lights nothing, tried charging, jumping ,new batteries,new terminals.Alternator. Ive seen older post/threads from Folks on here same issue,going way back like a bucket seat, no answers. Thank you for any help

 

Have you checked the visible link on positive battery connector.

 

,I took it & it has continuity,the 100 amp bolt in one,Right?

 

That's the one I was talking about. What about power further down? check ground wire too. You need to start from battery and work in both directions to confirm that you are getting power and proper grounds all the way to PCM. Check both ground and fat positive cable connectors to make sure you have not just continuity, but voltage without too much voltage drop.
