hi i have a 2001 polaris sportsman and it runs but back fires and is only reading 12 volts when i have the machine running i dont kno wat it is is there a way to check the stator wire or rectifier or something somebody please help me i just cant figure it out

 

Welcome to the forum! Pull the front plastic panel and close to the radiator is the regulator/rectifier. Check that all wires are connected. Should be a red,yellow,yellow/red,green and brown wire. Have had a problem with some on wires disconnecting from vibration. If the connections are good,then most of the time it's a burnt out reg/rectifier if there is only12 volts at the battery (should be around 14 volts)Check that battery ground and red wires are tight,another reason it could be not charging. Plus how old is the battery?? It may need to be replaced or checked out at any auto store on a load tester. May or may not have anything to do with the backfiring,but check the wires out first. Make sure the throttle has only 1/8" slack at the thumb lever. Excess slack can cause back firing. OPT

 

Does it run better with the lights off? If not, your problem is most likely not your charging system. If it does, get a volt ohm meter and check the voltage going in (AC volts) and out of the regulator (DC volts).

 

ok well the battery isnt even a week old and i checked the wires and they are all together i was wondering is there a way to check the rectifier and i have the wires from the solenoid they look all right all the terminals are tight

 

If you have 12 volts on the red wire going into the regulator /rectifier and shows only battery voltage at the battery while running, then order a new regulator /rectifier. This is what happens 90% of the time. #4060173 try this place,cheaper than some I've found. Polaris ATV Rectifier Regulator OPT

 

ok so i have 12 goin to the red wire and twelve at the battery so ur saying if i change the regulator it will have 14 at the battery let me kno plzz and thank u

 

Usually charged 14 volts (or there abouts) when I changed a bad regulator rectifier out! Which sounds like what you have! OPT

 

ok well im going to buy the rectifier and ill get back to you thank u so much for all the help ill let u kno if that solves it or not

 

ok now heres my problem i got a new rectifier and the colors are different then the original one now i have a brown wire a red wire and two yellow wires which ones get hooked where my original rectifier was exact color matchup to the wires when they plugged in so im lost can u help

 

Is this the replacement for this regulator or just one that came off of another Polaris? If its the replacement regulator then it doesn't matter which yellow goes to the yellow or yellow/red if the replacement only has yellow wires. If this is what you're talking about? Have found this before on replacement modules. OPT
