Kyej Posted March 9, 2017 Share Posted March 9, 2017 Hi there i have a Yamaha aerox yq100 I had this running and on the road for a few weeks one day I popped home on my dinner break went to leave again to go back to work and it wouldn't start what so ever and has never had a spark since. I changed a lot of parts on it and still no joy just had someone test round a few bits and said the regulator/ rectifier was the issue I changed it today for a brand new one and still no joy! ive changed the : cdi unit ht lead/ coil lead stator plate/magneto pickup regulator/ recitifier spark plug battery pratically everything to do with electrics and no one seems to know what the issue is I'm in need of getting it back up and running for the end of the month as I'm moving further away from work and will need it for transport, I'm on the verge of just scrapping it or torching it it's had a lot of engine work done to it also and about 5-600 quid chucked at it someone please please resolve my problem I will be so grateful!! thanks kye Link to comment Share on other sites More sharing options...
Moderator Cynic Posted March 10, 2017 Moderator Share Posted March 10, 2017 Sounds like you have been used as a cash cow. Anybody actually checked the loom. Or the ig and kill switches. Link to comment Share on other sites More sharing options...
Kyej Posted March 10, 2017 Author Share Posted March 10, 2017 I certainly have lol the bikes had hundreds spent on it and I'm still walking to work lol I've printed out the electric section from the manual to check all round the loom etc I did have a bad crash on it when I was on the road and the wiring loom actually snapped in half near the forks I had to sit there in agony and rewire the bike but I've checked where I did that and it doesn't seem to of broken or anything again also the aerox doesn't have a kill switch it's fine by key but someone else said it could be the ignition cancelling the spark acting as if the ignition is off thanks for getting back to me kye Link to comment Share on other sites More sharing options...

jimmy Posted March 12, 2017 Share Posted March 12, 2017 Is the bike turning over when you press the starter switch. Have you tried jumping the starter relay 1 Link to comment Share on other sites More sharing options...
Moderator drewpy Posted March 12, 2017 Moderator Share Posted March 12, 2017 is it those ones where you have to pull the brake lever for it to start? possible contact or switch faulty if it is 1 Link to comment Share on other sites More sharing options...
Kyej Posted March 13, 2017 Author Share Posted March 13, 2017 It's turning over without a fault I haven't replaced the solenoid but didn't think it would be that at fault as my starter motor is spinning over and yes it is one you have to pull the brake on to start it Link to comment Share on other sites More sharing options...
