ok today, i switched the brown wire back to negative, and took a voltage reading at the battery and as you rev it it still lowers the voltage in the battery, im lost. so would that the the voltage regulator, or the stator causing that, we took a reading directly off the red wire with the fuse that goes to the battery, and i get 9 volts, but does that mean that the regulator is bad or that the stator isnt producing enough electricity to power the system.

Going back to the stator you can unplug that 4 pin connector, run the machine, and measure AC voltage across the 2 yellow/red wires and if that's over 14 volts AC your stator is producing enough voltage.

Do you still have 3 browns attached to the engine ground? 2 off the stator harness and one off the CDI?

3 brown ground wires should be bolted to the magneto housing on the engine. 2 from the stator and one from the CDI. None of these are for charging the battery though.

problem fixed

the brown wire does go to the neg and the fused red to the pos, but the biggest thing is to look for broke wires, i found two broke grounds to the back of the motor, and where the charging problem lay was with the voltage regulator, im not sure if it was bad but the wires were weak where the connector connects and when i went to replace it the wires broke. so if your having a charging problem most likely broke wires, or the regulator, dont waste money on a stator, i bought a used one that the ohms didnt read much higer than my old one, which was well below specs, and still works fine, i fixed those wires tested the voltage at the battery and was getting like 14.5 volts. problem solved, thanks everyone for the help.
