Volt meter says 9.75 volts

Very low voltage. Charge the battery again until it's fully charged and try again. It should start fine then and then take it for a ride to the juices flowing inside the battery. Good luck and welcome to the forums.

 

I am dropping the battery off today for load test. Once I am 100% sure it’s not the battery I will take it for a drive and keep you posted. I was thinking it needed a drive but wasn’t sure if that would solve the issue. I will also test the voltage at 4000rpm.

 

Sounds like a parasitic draw to me. Hmmm

 

Where do you start testing for that? I have nothing aftermarket on the bike. It has a winch that’s it

 

Changed the Stator on Sat,

Just wondering why you had to change the stator,

Where do you start testing for that? I have nothing aftermarket on the bike. It has a winch that’s it

Charge the battery to 100% (should be between 12.5 and 12.75 volts). Do not connect to the machine. Let it sit for a day or two to see if it looses voltage from problem internal to battery.

While the battery is disconnected check the ohms between the battery cables on the machine. If there is a parasitic short it will show low resistance.

 

I changed the Stator because when the bike was running at idle the voltage was dropping to the point where the bike would stall. What is considered a “low ohm reading” I will test the battery terminals shortly

 

Oops my bad, it should test like an open circuit with no conductance at all and very high resistance. Basically the ohm reading would be 1 (prior to test, mine reads 1 with leads not touching).
A partial short or intermittent short could have the stator working hard enough to burn out. If your new stator did not solve the problem then there is most probably a short of some kind on the machine. It is not normal to be changing stators.
Does the battery charge up normally when using a battery charger?

 

Yes the battery charges good. I will know today if it passed the load test. If it passes, I will do a test on the battery leads and fuses… if I see a leak. Otherwise I guess it’s the voltage regulator… I always thought if the voltage regulator was bad the battery would charge high like 17 V, but somebody said in the forum that it can go both ways with a voltage regulator. It’s funny the battery died within 3mins. The new Stator the battery doesn’t die right away… it dies over time when the machine is off. The voltage stayed constant at 12.9 when idle. I do need to test it at 4000 rpm though….the voltage should go up to 16-17v when at 4000 rpm I never tested that last time…

 

mine is always between 14V and 14.3 no matter what RMP or loads (accessories).
12.9 seems too low for me 🙄

 

Ok. I will double check that Sat when I hook it up. Battery just finished load test. It passed

 

Would the rectifier/regulator have anything to do with this?

Absolutely. I would've checked it first, me, before diving off into the stator. Little too late now

The stator is responsible for creating the recharging juices, but the VR has to store/release the juice back to the battery, to recharge it.

Grab your service manual and check both for proper operation/output.

 

The service manual doesn’t give you any output info for the regulator. I did upgrade to a better aftermarket Stator anyways. The manual said if the battery dies it’s most likely a Stator so I started with that 🤣 at least the regulator is a 20min swap 😆. Thank you everyone for all the input. It’s been super helpful!! 🍻

 

**Update
so I hooked the battery up and tested the battery with the positive lead on the battery and the negative off (ATV not running) and I don’t have a draw anywhere. The battery is at 12.7v and it doesn’t go higher at either 1000-4000rpm. Took it for a 15 min boot around the block still no change. I ordered a upgraded voltage regulator (one with a built in shut off to avoid damage to itself) I should have the part late this week. Will follow up later this week again with another update.
side note this happen prior to doing any work…this being my first ATV when I ordered my battery I never knew the polarity comes directional…and when I went to install the battery in the dark The tail lights lit up and alarms in my head went off and I unhooked the battery… then realized the battery was wrong… what possible problems can this do?

Aftermarket VRs are known not to last long. Experience taught us to stick with OEM VRs. Thought you should know this.

 

Other times, other owners have accidentally hooked up their batteries backwards, they smoked their VR's

 

I have a VR on order. Should be here late this week

 

I was thinking that as well but I decided to go with a VR from this company. It seems to have additional built in shut offs to avoid future damage to itself. Seemed like a good investment plus that’s all this company makes. Do you would think there products are good. Not Chinese crap.

@CanAmRancher1 Can you comment on whether you have used their products before or not? Are they any good or do you think this VR will end up failing prematurely like the other aftermarket VRs you've used?

 

Rmstator is Chinese crap. Don't let their marketing crap fool you. I also assume you went with their stator?

I have tried using their VRs and they have never lasted more than a year. Plus they melted the stator plug.

The stators from them never put out good voltage at idle either. Ive never seen them charge over 13 at idle and they too died within a year.

Anymore if it isn't oem I won't put it on.

I’m no I didn’t use a RMStator, I used a Wolftech from Royal Distributing. So far everything works good. If anything happens in the future I will continue to update

 

They will warranty stuff but after having to fix stator plugs on every machine I put a vr on from rmstator I didn't even bother with warranty.

One thing I've learned many years ago, when it comes to electrical parts for any type of vehicle, stay with OEM! Even more important now a days with most aftermarket/third party parts are made in China. Not worth the headaches!
