Gilera DNA 125 - Electric-start broken?

My Gilera DNA 125 won't start up.. it was starting fine (i got it going several times and revved it a tiny bit), then i turned it off; when I later started it, it would attempt to, but not start up. I charged the battery - the power from the battery gets to the front (controlling the lights etc) but not the back to make it start. Have I disconnected something near the battery? The bike makes no noise what-so-ever when I try to electric-start it up. The bike should be mechanically working fine (I've just bought it), so I'm quite sure its to do with the electrics. Thanks a lot if you can help! Also I know how to start it up as I did it the other day on this bike, but this time it won't do anything, no matter how hard I try! Just tested it now, and when I turn the key to the 'on' position, then try to start it (holding the break and start button), the back break lights do not come on, yet the permanent back light does when I put the lights on.

The most likely reason for this is that the spark plug needs to either changed or at least cleaned. Two stroke engines are really hard on spark plugs, so get in to the routine of cleaning it at least once a month.
Ja.

Really the only way to sort it out is with a wiring diagram , a strong cup of tea and several aspirin. However, have a nose around, you may spot a disconnected connection (if you see what I mean). You sure your battery is holding its charge?

If you can't find it, it might be easier on your sanity to get a pro to look at it.

i used to have one of these ages ago,there is a fuse under the seat,right at the back which blows sometimes.that would cause it not to start.
