Battery Dying

Ok- I normally dont post on this stuff but I'm desperate for an answer that doesnt cost me an arm and a leg.

So I have a 2017 Polaris sport. I bought it just over a year ago and it has 125 miles on it and 10.5 hours of ride time.

Recently the battery died while my husband was out riding. We assumed it was the battery and purchased a new one. Immediately following this we went out for a ride and the battery died again. This time it died mid ride and we were forced to wait for the battery to charge itself up before we could continue.

In the process of getting it back home it died another 2 times while being driven. Something is draining the battery while it's being driven.

Can someone please point me in the right direction as far as where to start looking for the problem? The local repair shop wants 65 to diagnose plus repairs and quite frankly I dont have that money at the moment. The repair guy suggested it could be a converter(?) And I need someone to give me ideas on what to do.

Thanks in advance!

I am not an expert on such a situation but have experienced a similar situation recently and have remedied my issue. Have you added anything to your machine? A winch, light bar or anything else that may draw power? I added a winch and began experiencing the issue. The remedy was to clean up the starter solenoid and all the connections from the winch to the battery. I also added dialectric grease to each connection and made sure that the battery was connected properly. Almost forgot I also found two wires that had the sheathing worn and taped them up so that they would not ground out. The who process took about an hour to do and has resolved our battery drain issue. Hope this helps and best of luck troubleshooting.
A multimeter can help you find draws on your battery, there are videos on youtube on how to identify such battery draws with a multimeter.

ATVs aren't equipped with alternators, but they are equipped with stators and regulators. If your battery dies while driving, it means it's not charging. I would check the two components.

It's odd for a year old bike to experience this kind of issue. They can run for years without charging system issues.

@eduskator - Sorry to inform you, but the stator is the stationery part of the alternator and the regulator is part of the rectifier. The rec/reg changes AC into DC and regulates the output to 14.8 volts DC.

You are right, probably one of the two units failed - both can be tested. All you need is a multi-meter and the service manual. A little time reading to understand the mechanics involved and some time testing to determine which (if not both) has failed.

The majority of failures are caused by overloading - just running with a weak battery can cause a failure. Make sure the battery is holding a full charge before operating for an extended period of time. If the battery will not hold a full charge, replace it before the charging system is damaged.

Read the voltage at the battery terminals with the machine running at 3,000rpm. It should be between 13.5-14.5VDC.

I just checked mine at idle and I was getting 14.3 volts. I'd charge the battery to full charge and do the simple test with multi-meter while running and if you're getting anything below 13v then you have a charging issue.

What do you mean wait for it to charge? Batteries don't charge if not running, and you may need to be over a certain RPM.

I would check connections, being it is so new. Though it should run off the charging system I would think. Though I have heard of newer vehicles needing a battery.

One thing that is nice to have is a DC clamp on, they have come down in price. Though at idle you may be drawing off battery, but as you rev polarity should flip and go into battery.



Doesn't any one find it hard to believe a one year old machine could have batter volt reg or stator? Even a bad battery at one year is hard to believe, unless it was cheapo.

That is why I would check connections.

When you say wait for it to charge. Is it overheating or breaker/relay cutting out and turning machine off? Then after period of time cools, and resets? Only reason I am asking, is cause you said wait for it charge.

Low batteries often turn slowly or click. They are not going to charge themselves unless you jump start it with something.

As said you need a good meter that can read decimals. Should be around 12.7 Dc when the battery has sat for a few hours and close to 14.4 when revved up. After that you need to measure AC from stator, and find out how many volts AC per 1000 RPM it should be. At that point you if you have never done it going to dealer may be good.

I am also not afraid to throw parts at things. But being it is so new, it seems a waste. I don't mind doing it with old stuff.
