The wires look good, I'd like to put on new points and hope for the best. The flywheel is well magnetized.

I'm confused because none of the diagrams have 2 blues. White could be yellow, but most diagrams look like this. However, this one doesn't make sense because the other lighting coil isn't even connected in the diagram? So weird. I'm assuming the coil with the green on it is the LT coil and the other 2 are lighting coils, but maybe I'm wrong? Actually looking at it now, the coil with red connection (opposite the condenser) is the LT coil because the points connect to it in the photo I attached. Anyone care to explain this sucker? It looks like one coil only does the rear brake light? And the other does everything else? It's so weird because I've got an extra wire now that I look at it. The diagram has 5 and I have 6.

I'm going to guess that one of the blues goes to the headlight (yellow on the diagram) and the other to the tail/pilot/speedo bulbs.
Green to horn, red to ignition. Is one of them dead? I may have missed the genesis of this subplot. |

Looks like it's going to condenser is it supposed to be shorted through the condenser to the plate which is ground? The others at least aren't shorted to the plate. |

OK so here is where we are at.
I pinned it out and got resistances, see the photo. Coil 3 looks to be the LT coil (https://www.sip-scootershop.com/en/product/supply-coil-flywheel-charging-coil_85022000?q=coil), has yellow in and yellow out, attached to points and coil 1. Coil 1 is a lighting coil of some sort. (https://www.sip-scootershop.com/en/product/supply-coil-flywheel-sip-2-lighting-coil_16084510?q=coil). The yellow comes in from the LT coil and the green from the harness. 2 bare copper connections on it. From the sprint diagram above green seems to go to the horn and whatever else the switch might connect it to (the switch layout is unclear). Coil 2 is a lighting coil. It is different than most. It has 2 blues on one side and a white on the other. The closest I can find to it on SIP is this one: (https://www.sip-scootershop.com/en/product/supply-coil-flywheel-1-lighting-coil_16084400?q=coil). There is little resistance between white and either blue, or between the blues themselves. What isn't clear is if the blues should tie together, or if we should use this as 3 circuits. I know sometimes if you tie things together that should not be, you can get out of phase AC canceling each other. In short, coils 1 and 3 are just like the Sprint diagram above. Coil 2 is where I have a bit of a mystery going on. The new resistances are taken on a fluke at work, probe to probe is 0.2 ohm, as noted in the picture. Anyone have a known good points stator to grab me some reference resistances? ![]() |

if all else fails, there are cheapo 12v ac points stators from India, but I think we can use the one I have if I figure it out.

I have another really beat points stator, with the 2 wire coil 2. Blue and yellow show no connectivity to each other nor to ground. But I have no idea if that is normal or not.

I added the regular blue/yellow lighting coil to my Mercato cart. I can convert to regular VBB style stator if I just swap it out. I may still venture $30 on a 12V AC Indian points stator though just for amusement.

I love that you can edit the cart while they are still waiting for your SIP parts. I upped it to two lighting coils, so I can just get on with it and do a 12v ac conversion per this thread:
Converting a 6V stator to 12V Then I can use the BGM conversion harness and a 3 pole regulator and just not deal with the hassle of the balanced lighting nightmare. |

Working on the rear hub. Somebody thought it would be nice to powder coat the stub. Dumb. Didn't fit into the hub. Sanding fixed that. Now that it's together I am wondering if those "extended nuts" are supposed to fall into the holes in the drum? the drum holes don't look too centered to the hub studs, and maybe they won't fit down in there?

You want to bolt the drum to the hub when it's off the motor and without the wheel on? Why? Those shoulder nuts expect the wheel to be in place and those two small screws are all you need now.
You can use the wheel & tire w/ a wedge or your rear brakes to hold things when you tighten the axle nut. |

You can use the wheel & tire w/ a wedge or your rear brakes to hold things when you tighten the axle nut. i want to make a holder tool to do up the axle nut. I'm going to use 2 studs on the hub to do it. This will be done with only the 2 tiny screws in there. you don't even need the drum on to do this part, but my drum and hub are a tight fit, so I'm not looking to take them apart again unless I need to. (stupid powder coat). The shoulder nut question is because the drum looks a bit off center to the hub, and I'm wondering if those collars are gonna go down in the holes when I bolt the wheel to the hub. If so, I MAY need to make sure there is a path for them by opening up the drum holes slightly. |

I see. I guess I'd try backing the 2 retaining screws off slightly and running the nuts down into the clearance holes a little ways to center the studs, then just light snug up the retaining screws? I never thought about it before but when I mount wheels with these odd nuts(older smaller wheel studs need them), I can feel the resistance when they try to get in the hole and then they suddenly pop in. You could chamfer your wheel stud holes in the hub to help get them started if it's a problem, but I wouldn't otherwise open them up..

Agreed, but the top 2 of John's studs could be problematic and once the wheel is on you can't tighten those screws.

I didn't bring those weird nuts to work but I'll check the clearance for the collar and figure out what to do on that side if anything. I'll even try it with a wheel for fun, while not on the engine.
it's a hodge podge of parts, some Bajaj. not surprised it may need some adjustment. |

Disassembled it all, spun the hub 180, left out the little screws, centered the studs, and paid much more attention to drawing the stub in evenly by alternating nuts to pull it together. All set now.

If you have known good quality ones on the shelf, I'd so it while the stator is still on the bench.

That's the rub, are the new ones ok normally? Sometimes condensers are a crapshoot. I'm guessing yeah, do it.

well that turned into a bit of a debacle.
the new points were a different style than the old points. one has a post coming up from the plate and the other sticks into the plate. fortunately Kajiit has opened a new location in san diego and had additional stator plates to choose from. I swapped the plates and used the new points - done. the other debacle today was I ordered 2 lighting coils from Mercato of the blue/yellow kind but got 2 different ones. So I had to rescue an old coil and use it while I get the exchange worked out from Mercato. The old one seems to measure out OK, so I'll end up with a fresh one for a spare. |

for those who like me did not know, the pin type points can be used in the old plate with fixed post by removing it and drilling out the hole. (5mm = 7/32" for us yanks)
