What wire on the voltage regulator goes to the battery to charge it

 

Should have power to the main red wire in the regulator from the battery.Stator coil has the yellow and yellow/red wires that changes ac voltage to dc. Believe it or not the charge back to the battery is through all the ground wire from the main frame ground to the (-) battery post.Wouldn't get all flustered on what wire charges the battery,just mainly if all the wires are hooked up to the regulator. Some models including the 2002 were bad about the red wire coming loose from vibration. Check there first.If every thing is hooked up ok,charging is below 14 volts at 3000 rpm,most of the time it's a faulty regulator. You can check out the stator charge coil by doing a resistance test on the yellow and yellow/red wire. Should show some resistance between each other,plus no yellow wire should zero to ground. If that tests ok just replace the regulator. http://www.ebay.com/itm/Rectifier-Regulator-FITS-POLARIS-ATV-4060173-2203636-NEW-/270668566659?hash=item3f051a9083&vxp=mtr Plus here's an interesting test :
"Connect a tachometer to the ATV. The engine must be off. Put the negative lead of the ammeter onto the negative post of the battery, and the positive lead of the ammeter on the ground wire (s) that were connected to the negative post. Be sure that all ground wires have good contact to each other and do not leave any grounds connected to the battery for this test. Pull-start the ATV. With the ammeter set to its highest DC range, and the standard electrical loads turned on high, look at the ammeter readout. At idle it will almost certainly be negative. If it is positive your test is done—the charging system on your ATV is very capable. If the readout is negative, slowly increase the RPM level until the reading goes positive. A break-even RPM range of just above idle (on a warm engine) to around 2,000 RPM is standard for most magneto charging systems on ATVs. If the RPM must be increased to 2,500 RPM or more, the charging system was poorly designed for the ATV and you will have battery problems if you plan to operate your ATV at low RPM for utility purposes, or if you plan to run high-current accessories. On the other hand, if you usually operate your ATVs at higher RPM in fast trail-riding situations, the break-even RPM may not be much of an issue—as long as you are always sure to keep your battery charged". Plus here's another good explanation:"It is a common misconception that the terminals on a DC power source were designed so that electricity would flow from positive to negative. It seems intuitive, since positive, marked +, seems to indicate a surplus, and we think of negative (-) as subtracting and taking away. In reality, the cathode/negative terminal of a battery is labeled thusly because it contains an excess of electrons, which are negatively charged. The electrons flow toward the positively charged anode/positive terminal. You know this, of course; my point is only that the terminals are not accidentally labeled backwards. It was never intended that electricity would flow from positive to negative."
