Suzuki: Electric windows no longer work, jumper wires, fuse box


Question
I have recently bought a Suzuki Alto two weeks in the windows have stopped working. They are all electric and all dead.  Can you please give me some clues on where to look for the problem. The manual tells me nothing and the cost of the car has pretty much cleaned me out so can't afford a garage.  
Many thanks  

Answer
Let's try some basic checks first.
Obviously there are fuses, and you check them....
There are frequently fusible links (just a different kind of fuse) usually right at the battery positive terminal, although some manufacturers put them in the main fuse box.
There are two ways to go from there.
I have no idea what an "Alto" is so most of this is based on how most manufacturers build their vehicles.
Did the windows originally run independently of having the ignition switch in "run" (or "on") position?  If not, there may be a power relay operated (at least indirectly) by the ignition switch.  There may also be a master disconnect switch in the same general area as the rest of the window switches.  You could bypass these controls to see if they are defective.  If the control switches are in the door panels, it's possible that either a plug has somehow become disconnected, or in older vehicles, sometimes where the wires bend at the door hinge, consant flexing can break a wire (almost always in the driver's door first, because it's opened and shut the most.   
Another diagnostic test path would be to remove a door panel, and power the motors with an external pair of (FUSED!!!) jumper wires.  
It seems probable that since they are all dead, you have a power supply problem.
Check out the above things, they are almost always the cause of the problem. Always be methodical and consistent, and go from an already verified good source of power as much as possible.  And example would be: battery-fusible links-fuse box-fuses-ignition and power relays-switches-motors-ground connections.
If not, contact me again.
You will need a test light, some wire, "alligator clips" and a couple of in-line fuse holders, (don't get plain fuses, get a couple of self resetting citcuit breakers, that way if you inadvertently create a short with the jumpers in testing, you won't continually have to replace one-time use fuses)
