The BMS site these pictures came from lists two different stators for the 150 Pathfinder......I suppose different years came with different stators, but there is no way of knowing for sure off this site. I assume either stator could be bolted on the engine (since the engines are the same for all years). My question.....which stator is likely to have the greater output for DC charging purposes.? The only difference I can tell (other than the coil number)....the 11-coil stator has two yellow wires from the stator, vs 1 yellow wire on the 8-coil version (that's what I currently have). I'm looking for a greater charge capacity....assuming I can get the wiring modded correctly (perhaps with a different regulator), is there any way to know if the 11-coil stator would be worth the trouble (cost $60 w/flywheel)? From what I've read here, the 11-coil stators aren't much stronger.....   List of BMS models either stator will fit.. Heritage 150cc Grandprix 150cc Pathfinder 150cc V9 Evo 150cc Sabo Tiger 150cc TBX 150cc The wiring diagram for this scoot only shows one yellow wire from the stator......not much help other than that.  |

Ok...let me re-phrase the question. Does anybody with a 150 GY6 scooter know for certain he is running an 11-coil stator?
If so......will your headlight work without the engine running (running on DC)?
And.....what wattage is your headlight(s)?

bluefront, email me at (bobogeorge@gmail.com), I will get you all the info you need. A past member knows these stators inside and out. I can get you in contact with him.

^^^^^Well if the wire diagram (which matches the plug and the wire colors on my alternator) is any indication, I have the 8-coil stator. As to that other site mentioned......I'd just as soon avoid that place entirely, no matter what they have posted. This Scootdawg board has 10x the membership and at least 10x the credibility....IMO  |

Sorry you feel that way but I was just trying to help you bro!!
Many have put HIDs in that scooter and its all there for you. I don't know why you mention that ScooterDoc forum doesn't have credibility. Number of members does not create credibility, its the people that do. I belong to that forum as well and I was just trying to help you get the information you need so you can install the HIDs that you want on your scoot. But like they say you can lead a horse to water but you cannot make him drink.

Just in case some new Scootdawg members are unaware of the reasons that I will not make any use of that other board.......it has to do with unethical forum activities, which got certain persons banned from Scootdawg, who can now be found on that other board. Simple as that....

In life when someone has something I need or want, I will humble my self to get what I need . Eating crow is a way of life. The beauty of the fourm is all posts are logged. You need not ask, just help yourself and search. Interaction is not needed with members. How ever interaction is by far most helpfull.

I think this thread has devolved enough.
On something tangent to the original, I once entertained the idea of putting an 11 pole stator on a 50 cc bike, but couldn't find enough information to tell if there was a way to make it even physically fit. Does anyone have any information on that, or know someone who's tried it?

From the info I've gathered so far......the mount holes are the same, and either stator will fit the same 150cc engine. The 11-coil version requires a different flywheel, and a different regulator.....as well as wiring mods. What I haven't determined.....how much benefit will you get from the new setup? I'd like to see around a 70W increase in the charging capacity. But it's hard to find reliable information comparing the outputs of either stator. If you could find a standard scoot with an 11-coil stator that had a DC headlight.......that would be at least a 35W increase over what my 8-coil stator has. But that brings up another question.....are all the 11-coil stators equal in the charge capacity?  And for that matter.....could you find an 8-coil stator with a higher output than the stock 8-coil stator (that would bolt on of course)? |

As a member of both forums, I'm sorry to hear you say that Blue. For the record, I've never known anyone over at Scooter Doc refuse to help somebody out. Your loss.

Here's some info from gy6rocket... Here is a graph from that thread about why an 11 coil is superior to a 4, 6 or 8 pole style. the 11 coil uses 3x banks of 3 coil windings. (9 coils) for charging and 2 coils for ignition output, (9+2=11). The 3x banks of 3 coils creates, 3 phase current which is shown in this bottom row of this chart: (BTW) Rectified + Filtered AC = DC current  DC output is much more stable. When testing with my mutli meter each 3 coil bank outputs about 4.5vac - 5vac depending on the engine RPM, resulting in the post regulator system dumping 13.5vdc - 15vdc into the battery. Unless you dump over 12v into the battery , it's not really going to stay charged.  |

^^^^^Thanks for that last photo. It confirms what I suspected about the necessary wiring mods to the new (required) regulator....quite doable. And it shows an HID setup in operation, indicating an additional 35W DC draw (at least) over what my current 8-coil stator is capable. So there are three yellow wires from the stator....stands to reason. I'm left to wonder about the 11-coil stator assy itself.......as to if there is an 11-coil stator different (better) than other 11-coil stators. The total parts cost to this conversion would be around $100 or so. Not too bad.  |

After more searching.....here's the regulator that goes with the 11-coil stator.  I've searched, but haven't found the pin-out for this model.......which color wire goes where. I'm assuming the three yellow wires are interchangable.......the three others are not. Anybody? One other question.....how does the tachometer pick up the ignition signal. Off the trigger coil I suppose.....which would mean a connection to the coil positive wire somewhere in the harness? |

I pretty certain the tach on my 50 scoot is fake, just a voltmeter tapped off the white wire on the stator. Turning on the headlights makes the reading drop as much as 2000 rpm, even if I'm accelerating. Its only worth is as an estimate at best. I don't know if or what other scooters use a more accurate method (like trigger pulse).
On the bright side, if I run my lights in the day like I should, it does serve a useful function:
In the day, I can't see the dash indicators, so I don't know if I left the directionals on by accident. The tach needle will alert me to this by fluctuating/rocking after the battery is charged. If that catches my attention, I know to kill the flashers.

you can put a 5 wire regulator, ilke in some japanese , italian, european scooter
as far as you have the three yellow in imput
with them it s simplier to make your adaptation
after the lone mode you have to make is usually disconnecting the resistor where the current is derivated from light control switch, when you don t use lights
even if you can use a 11 coil in a 6 coil rotor (usually you can) you output will be low, because magnets on the rotor are not aligned with the coils

Here's a picture of a 4-pin regulator........I'm looking for something similar for the 6-pin regulator shown above.  This new setup would remove all the AC current from the lighting and other systems in this scoot. There will be some wiring mods necessary.....in the choke for sure. These necessary mods can be figured out using the stock wiring diagram. Now if only I could find a wiring diagram for a Pathfinder with the 11-coil stator.  |

No need to go another scooter board to find information. The Scootdawg forum is all you need.......along with a little Google help. |

No 11 coil stator install here that I found. Googled and found the install I mentioned.

Hummm.....very curious here, Miss L-Jackson. Just where did you receive enough technical training to enable you determine if a certain how-to on scooter stators....was "awesome"? Was it someplace in Little Rock perhaps........  |
|
And for that matter.....could you find an 8-coil stator with a higher output than the stock 8-coil stator (that would bolt on of course)?
