OK guys this maybe from left field
OK I have a scooter with a 6 coil stator and a four pin regulator during the summer my regulator went bad , I ordered a new 4 pin regulator . Great my scooter started to charge again (then was overcharging 15 to 16 volts )
So I remember seeing something about some wires being reversed .
What my question is what is the symptom with the reversed wires?
The regulator in the scoot is stamped FLP when I got another FLP regulator its perfect 14.4 to 14.6vdc
head light s are a/c ( would switching the wires make my head lights dc).
what about the color of the plug ?
let me know what your take is on this one ?

Here is a diagram of my rectifier:
 The reversal that I think you are referring to is that many of the old manuals have the red and yellow wires reversed. All I can tell you is my experience with my Bashan 150cc. The white wire comes off of my stator and runs directly into the rectirier/regulator (R/R) which I think is then rectified to DC for the red. The yellow plugs in but is split with a wire running to power various AC systems including the headlights. The red carries a DC current to the battery. So if you did have an old rectifier, which I doubt, you would indeed have a DC current running into the yellow wire and AC to the battery. It's all 12v after the rectifier (kinda) so I don't know that it would harm anything. However, I think the fuse might blow in the red wire. Here's a video of a crazy guy testing his rectifier and you can see the wire configuration if you stop it:

Right-on Bashan! The red and yellow are reversed in 95% of manuals I have seen...
It should be red to the left yellow to the right on the top row...

i was interested in what the syptom was , over charging not charging blowing lights

This is a clear diagram of the interconnection between the stator, coil and CDI from our good friend and member Sprocket:
If you reversed the red and yellow, AC current would flow to the battery and blow the fuse as soon as the polarity shifted, like hooking your battery up backwards. The white is rectified to supply the red so if you reversed them, nothing would flow, the DC can't flow back through the rectifier. So in my opinion the short answer to your question is, you can't reverse the wires. Rich |

There is a new version of this drawing. I just found it and it had a few errors which I have fixed. This one has the correct colors for the pick-up coil wire Note too this is for an AC CDI. The DC versions are different Attachments:
