Not the green fuses - to the left of those are 5 exposed fuses - check that these are not burnt out - they should be unbroken.
If worried about removing fuses to check them just remove the battery terminal first....then you can do no harm. Its only when people remove fuses when the engine is running or the ignition is on that problems occur.
I'd also locate the starter motor and make sure the cables going to it are not loose - same for the battery. Loose or corroded cables can cause your problem and are prime suspects.
Also check if your headlights are bright with the engine stopped - if not then either battery is buggered or cables to battery are bad. Terminals that go onto battery must be clean and tight. Good Luck.
