2017 Polaris Sportsman 570 Charging Issue?

Recommended Posts

Charging issue?

I have a 2017 Polaris Sportsman 570 EFI. Yesterday, I start the machine and it says low power (10.6-10.8). This machine is on its second battery. This is a new AGM battery with 50cca more than stock.

Should I look at the regulator or stator?

Thanks!!!

Easy test is with a meter on the battery, should read 12-13 volts with the machine off, start it up and rev it a bit, should read 13.5 -14.5 volts.

Polaris battery have be known to fail early, but since you have an AGM replacement, could be something else

I have a 2017 570eps model, that model has a ghost draw, my battery goes dead after 3 weeks. Haven't tracked it down yet.

I start it at least every two weeks.

My old Yamahs Kodiak would sit for 3 months and start right up...

Like @mikeexplorer said, it should be 12-13 volts, so it seems you are definitely low. I would check all the battery terminals and check for a draw.

Check your stator wires that run over oil filter they usually rub on engine.

Agree this! Found almost through rubbed wires on mine during a other service work.

i gotta 2017 570 too and its been a great machine.  i would check for any loose connections between the stater and the battery.  also check that your stater isnt blown and check your reg rectifier.

im running a $30 dollar cheap aftermarket battery in mine and it does fine- has a little issue turning over with i have the lights on or some draw on it but thats because it was made for a 300cc atv, not a 570 lol.  not sure what the cca are on it

Any accessories on the vehicle? if so check for a draw on the battery with the key off.  The service manual has instructions on how to test  the charging system if the stater tests normal and you have no draws then I would suspect  the voltage regulator is bad.

      Hi all,
       
      Picked up my first Brute Force yesterday. What should have been an awesome afternoon of riding turn a bit into a deception. As I was unable to really take it out for a test drive at the shop, I decided to buy it and agreed that I would take the test drive at home. 
      When giving full throttle I noticed that the Brute was choking and lost all of its powers. Faulty fuel pump most likely. 
      Called the shop and the are coming to pick it up and repair it and bring it back. Good service. Nevertheless feels a bit sour in the mouth as I was told it was a 100% good. 
      Need to have some patience I now before I can really start riding. 
      Cheers,
      Erik

      Just now rolling over 100k miles. Been feeling some steering weirdness so I get one front wheel up in the air and push at 3 and 9 and sure enough there's some wobble. Pushing at 12 and 6 gives no play at all.
      Although I'll probably be replacing the worn part myself I need some help diagnosing what all might need to be replaced. And since I need an alignment anyway I've made a deal w/ my local Goodyear tire shop to do a pre alignment inspection and identify my bad part(s) so I can replace them before they do the job.
      When I drop the car off what specific parts should I ask them to look at? I'm sure tie rod ends but what other kind of worn parts could be causing movement on the 3-9 push test?

      Hi I just got an Polaris sportsman 500 4x4 ATV the other day. I got it real cheap but I started to go into it because it didn't have compression so I bought a new piston and ring kit for it and installed it, but now when I try to start it all it does is shoot fire out the exhaust or the intake of the carburetor. And a timing is top dead center.;I think I can't really tell another way if it is or not. when I put it together I made sure to piston was on top and the cam lobes where facing down where are the cam sprocket is facing up. It has gas and spark. It did start a couple minutes ago but it didn't stay running and now it won't start. Do you think the valve need to be adjusted more to close better?I'm fixing to try that out and if that don't work what is the problem? Also I made sure everything was together good and right and change the oil and changed out the radiator fluid.

      I just rebuilt my 03 sportsman 400. Put everything back together added oil per the manual. Pinched off the oil tank vent line 2" away ran for 45 seconds then cut it off. Check oil level and it was still way high so I wasn't confident that it primed so I did it again. Checked again and it's the same. Remove the oil filter and it is dry. I did the procedure again and the same results.

      I'm worried to keep trying this as the only oil in the engine is what I used to lubricate the parts when reassembling the piston. The crankcase was drained as well.
      I Removed the oil tank and checked all the lines for obstructions and the screen filter and the vent hose and everything is clear. I even pulled a small vacuum on the oil tank while it was pulled off to make sure there were no leaks. The dipstick cap was on tight so I'm not sure why this thing is not priming.

      Anyone have any suggestions. I thought about pre-priming the oil lines from the oil tank to the crankcase to hopefully help the system prime. I'd like to be able to add some oil to the crankcase to so I wouldn't feel so bad about running the engine for another 60 seconds without oil. I dropped just a little bit of oil in the spark plug hole to help condition the sleeve right now.

      What do I do? Anyone had or heard of an oil pump failure on these. Btw oil pump is working fine before I did the top-end rebuild and the oil pump was not touched.

      Please help!!! Thanks all for any and all help.
