Looking for a wiring diagram online for a polaris ranger. Someone diconnected the starter and I need to connect wires back to it.  

More than likely you can get this info at "powersportsnetwork.com".  If not give me a blog back as my name is navychief.  

be careful with that ranger, someone posted on here that theirs caught fire in the night and destroyed half their house and their new car.  

2003 polaris ranger, stalls after start quickly and if it does run stalls when lights are turned on, any suggestions?  

alot of things it could be,  first to mind is that the stator is weak, or the voltage regulator isn't allowing enough voltage.

but it could be as simple as not getting enough fuel, so that with the lights on it stalls under the added strain of having to produce enough votage to maintain running.

again there alot of possibilities.

does it run fine while holding the throttle?
or cut out or bog down at high throttle?  

I also have a polaris ranger that is running low on voltage. Is there a way to check the voltage regulator? If so where is it?? We have narrowed it down to either the regulator or the alternator. Not sure where to find either or how to check for sure. Can anyone help?
