6pole to 8 pole stator upgrade question -rectifier By godfeast (Read 6,151 times)

Is the black a power lead or a ground? what does it normally hook up to on a system with an 8 pole stator?

My new 8 pole stator came with a 5 pin rectifier/voltage regulator where as my old 6 pole one had a stock 4 pin regulator. I attempted to use the old 4 pin and blew out the headlights, so i need to convert.

This is simple and complex at the same time, let me try to sort this out:

• Eight pole stators CAN be compatible with four pin rectifiers, my Bashans are four wire and eight pole.
  
• If you can get the right rectifier it will be plug and play for your bike's wiring. Rectifiers are NOT universal, I don't care what they say on the websites.
  
• Your bike is wired for a four pin rectifier, you'll do some serious wire stripping if you try to use that rectifier.
  
• Having said that, the five pin would be red to battery with fuse. Black is a hot 12v DC to the ignition switch. Ground the green and connect the whites and yellows.
  
• Your present wiring configuration is probably a red from the battery to the ignition switch which energizes a black when the switch is on.
  
• You could try swapping the black for the red to the switch, I'm not sure what would happen without seeing an ACCURATE wiring diagram of your bike.
  
• In regards to getting the right rectifier, I'd call one of these guys and tell them your plight: Greg at Mainely Scooters, Dave at Absolutely Scooters, Mike at BPNW, Tom at KidNMe, or Scooter Elements. When you call tell them Rich from Scooter Doc says hi.

6 to 8 should have been a plug and play . If you have to play with wires to make it work imo you would have been better off to go to 11poll stator and 7pin regulator , only two wires to splice into the harness . The hardest part of the whole mod is getting the flywheel off .

Time is a serious issue atm, or I'd just buy another 6 pole with a 4 pin regulator and be done with it myself.

This is my only ride to work and my backs up against the wall to get it running.

The basic scenario is the engine in it currently came from ebay last year with the 5 pin regulator and because of the regulator issue, I swapped my old 6 pole into it and that stator has recently died, leaving me to reinstall the 8 pole and quickly receive a freshly burned out 4 pin regulator and blown headlight bulbs ( forgot about the regulator issue when I swapped it back in).

I tested 50 volts coming across the headlights at mid wot.

I need to make this 8 pole + 5 pin regulator work asap or risk losing my job and all the things that go with that; Not fun.

Now, when you say serious wire stripping, do you mean I'm going to melt the headlight harness out?

If so, does that indicate a need to rewire with a heavier gauge wiring or would that just cause other issues?

I have the tools and just enough knowledge of electronics to make the worst of a situation like this.

OK, so we gotta roll the dice eh? Refer to this diagram, it's probably a close approximation of your four pin wiring scheme. Hook the red on the 5 pin rectifier to the positive battery terminal with a 15 amp fuse. You can't use the red wire in the bike side rectifier coupler. Just unplug the red wire that's on the ignition switch and tie it off. Run the black on your 5 pin rectifier to the red lead on your ignition switch (hopefully it's a four wire switch). This is a guess so stand back and turn the key. Hopefully the black wire will give you the 12v DC you need to the ignition. Rich

I tried and the scooter wouldnt even turn over with the new regulator in.

I was always worried that this was setup as a dc engine when I received it, so I may still be dealing with that.

I tried to ride the bike with the older burned out regulator in (mistake) because it fired up and I took the headlight harness off. I got maybe 20 minutes out and the bike shutdown and wouldnt start up ( sounded like a dead battery and kickstart wouldnt work either). The battery had been fully charged.

Im just digging in deeper atm...
