I have modified my stator by making it full wave, moving the yellow wire to the winding that was connected formerly soldered to the ground, now I am getting no power output when I check it at the harness and plugged in no charge on the battery. I have continuity between the white and yellow now so the circuit is complete and not open somewhere as I first thought. When I check the ground wire it also has continuity when checked against one of the bolts holding the stator to the case. What could be the issue?

You don't have it hooked up to a full wave rectifier?

Yes I do, I was testing it from the harness though, I have it working now its an 8 pole stator and it was showing 60-70v at about 5000 rpm does that sound about right for output? Also I have a cheap ebay full wave rectifier on it currently, would I be better off with a trail tech 150w? The battery was only running at about 12.9 v at the same rpm and 11.9-12.1 at idle. I feel like the ebay rectifier is limiting my charging?? Or is it just me. I don't know how to calculate the actual wattage output of the stator.

Good deal.
60-70v at 5k with stator disconnected is fine. The reading at battery during idle is low. Could be bad battery, good battery discharged or stator problem.
What volts at idle with stator disconnected?
I have a 150gy6 with 8 pole, single phase, full wave. I installed a digital voltmeter on the dash connected to switched 12vdc and it pulls up to 14.5 at idle within maybe 30 seconds after starting, like clockwork. I also replaced the scooter batt with a riding mower battery years ago and the magneto keeps it charged perfect, no plugin charging.
Not sure about the Trail Tech 150w. Manufactures don't tend to give out the specs on this stuff. Only thing I've gone by is the main fuse rating of the machine. If it's a 10amp fuse, then its a 10amp system. General math says 12v system x 10 amp = 120 watt system. The only 150 watt systems that I've seen with these magneto's was from a 3 phase configuration.
