This is and has been my most reliable scooter ever, not even a blown globe....... until now!!! I use it as my daily runner traveling about 65 to 70 km per day.
I recently sent it in to have new rings put in and when it came back I have been having problems with the electrics. It has been blowing brake light bulbs and doesn't start on first kick like it used to.

I started checking wires and eventually decided to check the stator to see if it was faulty.

After opening the junction box I found a bridge between red and blue. This explains why bike was still running after blowing the brake light globe.

On the stator I found wiring that does not tie up to any diagrams I have seen or found on the net.
I replaced the condenser as the red wire had started to corrode and the insulation was cracking.

I am at a loss!!! Before I go any further, can someone look at the pics i have uploaded and tell me I'm not going mad.

Like I said earlier, most reliable scooter ever till someone else fiddled with it.

I need to know if the stator is workable in its current setup and if anyone has seen this wiring setup before.

Do you have the original stator? This one looks aftermarket.

If the work that was done was mechanical I would be inclined to look for damaged wires, incorrect connection, or lack of earth wire to the engine. As your stator has three completely different coils on it I would guess that its a system designed to run without a battery, would I be corrected in thinking it has no rectifier? Again just guessing but I would suspect that the coil with fewer turns would be a high current feed to the ignition coil and could be wired through the CB points.

The red and blue have absolutely nothing in common in my opinion. Blue goes to brake light, red to ignition coil. To have them bridged must fool something up.

That is true if the stator was wired in standard format. It worked fine for 5 years without me having to touch anything regarding the electrics. Not even a blown globe. Thing is the guy that worked on it did something to it and now I'm having these priblems.

Correct. No battery, no rectifier and ignition coil is top middle in pic above. Red, connected to points as well.

Im starting to wonder if i should put a vespatronic on this scoot as well or the new ignition system SIP has just released made by Vape and ditch this stator. It generates 12v 110w power at low rpm. Comes in both DC or AC.

Yes, of course, stupid of me.

Thanks Waspmike but i have that diagram as well.

My question is my stator is wired differently to the diagram and have worked well for 5 years with this configuration.

Based in the photo i attached here of my stator and the way it is wired, which way do i connect it up again at the junction box?

Looking at your pictures again.

If it all worked when you took it off and as it has all the same coloured wires as the no battery diagram here. http://scooterhelp.com/electrics/pages/VBC.150super.html

Don't over think it.

I would connect it up as per diagram. Red to the coil, black is ground, yellow, blue and green are lights and horn.

When the engine runs which it will and things are not according to plan that bridge can be crossed at the time. Probably switch the green and yellow as it looks as though coils 1 and 3 have been reversed in function and that yellow becomes the new green.

Try it the original way first. If the side/running lights are dim and the horn is loud then..

If the scoot has been modified for the addition of a battery as might be indicated by the connection of coils 1 and 3 we have to think again.

@Wapsmike

Thanks Mike. I did exactly that last night. I wired it up as per the diagram. It starts, runs but no lights and hooter very loud. If i press the brake, the scoot dies but then tail light works until the scoot is dies.

Also tried switching yellow and green but it also didn't work. I realised now I didnt swap them at the switch as well so I will try that again.

I have a spare stator from my other sprint that I am going to put on tomorrow and see is if works as that stator is wired as per the diagram.

If it does the same, then I have a new wiring loom that I will fit to the scoot but I'm not looking forward to that job since I did that on my Rally 200 and didn't enjoy it because I struggled for hours and hours and hours. Worst of all was the Mrs complaining about how long it was taking. Best thing was not having to go shopping with her.

If the above doent work then I'll just send it to the auto electrician and pay him to deal with it.

I live in George and have restored a lot of 6V Vespas. It is quite easy to upgrade to 12V, but if you want to keep it 6V, I can help you with the wiring.
