The ladilla does not start

I have an NIVA 21214 of the year 2004
, I have problems after having tangled in the alternator and having changed the rectifier and regulator, when I have mounted it and I have gone to start the battery I was a bit spent and did not turn the starter engine well so taking advantage of the slope I have tried to start it but it has not been possible.
When I have gone to the contact key of the electrical system again, nothing except the electronic immobilized,! Ni ning, radio, lights, interior lights, or anything, it does not turn on either the picture thing that if I did before,
is there any general fuse apart from those under the steering wheel?
Where can the breakdown be?
The alternator I have disassembled again because it has been short -circuit, but still still without an electrical system

The large majority of vehicles have a block of main fuses in the engine cabin, there are those of power such as the fuse of the alternator load and the battery positive to the cabin or the ignition, check those first

Arranged, new alternator on eBay and now goes like God
thanks to all.
The good thing is that now I have a diodes plaque and a spare rectifier
