Ah Ha, you did nail it from the start. Too bad your student was not slowing down long enough to pay attention. Thanks again.

Alleyoop steven Ok I think I am ready to take another stab at this diagnosis again. Correct me anywhere along here if I am incorrect. 1) I know the Scooter STARTS with the kick starter. ( in looking at the schematic, IGNITION SWITCH is OK, BRAKE SWITCH is OK, R/R is OK ( what is this by the way?), PLUG COIL CDI STATOR are all OK. STARTER will crank over and start scooter if I jump SOLENOID, so STARTER itself is OK. OK SCRATCH ALL THAT FROM ABOVE, or better yet, if the next person has a similar situation as above.... CHECK THE FUSE in the battery compartment. I was trying to avoid having to pull the floor board and get to the battery, was just going by voltage readings from my remote charging wire I have accessible outside the floorboard. What a dummy I feel like. I had started listing all items that I knew were not running and was going to ask for voltages at these items, then when I got down to the battery on the schematic in BOLD letters FUSE. So I went out took off the floor panel I was trying to avoid having to remove, and guess what, BLOWN FUSE. (by the way what Amp of fuse do I need to replace with ) lucky for me Strada has a replacement fuse included. Replaced fuse. Dash comes on, starter turns over with start button. Wow that fuse almost cost me $900 that I don't need to spend at this time. Had my eye on a 50cc TAOTAO Thunder. I want to thank you both very much for all your input. I have known people who just love to diagnose problems like this, me personally it is a living hell, I get too frustrated and OVER LOOK the obvious. Still don't have a home for the lone ground wire. I did disable the ALARM system on this scooter when I bought it, may have been from something on that. Thanks again, and safe Scooting. David

I was hoping you guys were on to something that I was obviously looking over, but that black wire has a black/green wire plugged into it. The black wire goes to the smaller of the two square objects just behind the horn, ( what are these by the way, not that this has anything to do with my situation, I am just curious on what the identification of these items are ) Thanks.  |

 Hope this uploads, here is a pic of the green wire and what is left of a crimp fitting on it. It goes down 3 -4 inches then joins the Main wiring harness and continues down to who know where. This wire does Ohm out to be a ground wire to something. |

Steven, Brake Switch/ Starting problem : No, starter does not engage when brake is pulled and push on starter button.
I have taken apart instrument plastic housing. Kick Started scooter : have found NO green wire that does not have a home behind this housing. I am noticing no left turn light, right signal will not flash. No horn, flasher is giving me an annoying buzzing sound until I pull on a brake switch.
I will do the Ohm test on the green wire, but still not sure I will know what and where needs grounded, not looking to good for the home team on this project.
Thanks for everyones help.

It is a SOLID GREEN wire. Has what is left of a crimped connector on it. Wire is going down the main wire harness. I am not finding any of the Large connectors with missing plugs, or any stray wires that have a connector not hooked up. I am drawing a blank here. I was hoping that I was missing an obvious stray wire I could not locate in the dark last night, in daylight I still find no home for the stray green wire.
Do you have a clear wire schematic for these scooters. I found one, but when I zoom in on it everything gets blurry.

In looking at several wiring diagrams, it looks like one of the wires on the brake switch is a green one. Might be close to being able to put the Scooter together and getting back on the road tomorrow. Wife and I purchased our scooters in 2006, thought that this might be it's last time on the streets.
Thanks for the help.

Look for a BLACK/WHITE striped wire that is the Wire that KILLS the motor so you need to swap the red wire with the BLACK/WHITE wire. The Red wire should have voltage coming from the battery. And the way it works is VOLTAGE is always present at the IGNITION then when on it makes contact with the black wire which in turns feeds everything else on the scoot. The lighting usually comes from the Regulator/Rectifier or straight from the stator look for a white or yellow wire from the R/R or stator go to the front of the scoot. Now the running lights is feed by a brown wire. Yellow/Green is your brake lights as well as the feed for the SOLENOID for electric starts which is fed from the brake switch. Alleyoop Alleyoop Thanks Alleyoop, after switching B/W and Red wires now the ignition key is working as it should. After starting this last time I did notice lights and dash are coming on as scooter is running. So now I just have a Brake Switch/ starting problem. Now that it is darker, I did notice a green wire pulled from somewhere and was arcing against the horn. Tomorrow I will see if I can track down where this Green wire goes to. Thanks David |

Just preformed some tests : Jumping coil test - Starter turns fine, so Starter & Battery are fine. Spark Plug check - NO Spark at the plug. I did have the ignition switch in ON position, not knowing if this makes a difference. I will check for spark in OFF position - I DO have spark in OFF position and scooter will run. So that would eliminate a whole other set of electronics.
So I have a switch that may just need a wire switched on, and still NO dash light or ability to start with brake and starter switch.
Now any advice, Thanks
David

Will give a little background. Scooter is 7yrs old, been running fine. Let someone borrow to take there Driving test for there licence. Went to start about a week later, and I pulled the ignition switch out of the dash. The cast metal had broke and ignition was in 2 pieces. I could not ever find the ON position of switch ( May have broke in the ON and battery may had been drained ) Ordered a new switch, put battery on charger. Just installed switch today, still everything is DEAD. No life what so ever.
Where can I start on this diagnosis. Feeling frustrated at this point. Lesson learned NEVER let someone borrow your scooter. True it's not a name brand expensive scooter, but it was a good runner just the same.
Thanks for any advice.
David
