Piaggio NRG 50CC 2005 WONT START

[Brillpiaggio]

Hey guys, let me start by saying this, im 16, first tim buying a bike got a piaggio nrg 50cc for a decent price was hoping my dad could fix it as he is a mechanic but for cars, he hasnt has soo much luck. So lets start well basically when i bought the car a lad near my dads garage saw that i was trying to fix it and he put in his diagnostic or whatever and it appeared the problem that it wasnt starting was the motor relay and Also bought a HC OR HT Coil forgot what it was called, got them both for about £30 so wasnt too bad, so carrying on my dad fitted them in, i think my dad fitted them in correctly as the engine sounded a lot better however, it still did not start. the next day as im waiting for my dad to come back and carry on trying to fix it i put the key on without even turning it to ignition at all, i hit the kick start and it sounded lik it nearly started so i done it again, and it started!, the dashboars lit up, where i was very excited revved it abit till 4-5 , i also noticed that the light with the tap turned on and it was red which worried me so i turned it off tried turning it on again it turned on, so i turned it off . So i waited ill my dad came and we then tried again, and had no luck, so my dad tried multiple things such as linking up the moped battery with a car bosch battery with some jump cables and had no luck again.Very fustrated as we have been trying to fix it for 2 weeks now. The spark plug has spark, the bike has oil, it has fuel, anything else i could check? At one point the fuse blew, which i think was when we tried to jump start with a snap on booster which did not work (the fuse was replace) WOULD REALLY APPRECIATE ANY HELP OR SUGGESTIONS FROM YOU GUYS IF MY BIKE FINALLY GETS FIXED I WILL BE MORE THEN HAPPY TO
MAKE A LITTLE PAYMENT AS A FRIENDLY GESTURE, as im only 16 and trying my best to get a job. ANY QUESTIONS YOU HAVE GET AT ME, I WOULD BE MORE THAN HAPPY TO HELP AS I REALLY NEED HELP, cheers LADS

PS: ALSO ATTACHED A PIC OF THE SPARK WHICH MIGHT HELP SO I KNOW IF IT NEEDS TO GET REPLACED
