So my 14 crew 800 came with a larger battery than the older models and it's located under the rear seat drivers side. Not sure if the battery is bad or if I should just ignore the low battery prompt, but at night all I will have on is the headlights and a smal 12" lightbar. Within a few minutes and running the machine, the low battery indicator will come on.

i would eventually like to replace that lightbar with a 30" bar but will need more juice to power it. Would I be okay with a good replacement battery or would I be better off with a dual battery setup under the back seat?

What at are yall running to power all of your light bars and accessories?

Sounds like maybe the dealer didn't properly prep your battery(?). You should have plenty of juice for what you described even if you added a 30 incher. Remember, your max output from your stator occurs around 3000 RPM - if you are just idling, your stator may not be keeping up (but I doubt it!). Charge up your battery manually and have it load tested. What battery came with your unit - how many hours do you have on it?

To do that would you recommend I remove the battery, charge it, then take it to an autozone for load testing? Or does the battery need to stay in the unit and take the whole unit for load testing?

Remove the battery from your buggy, charge it, let it set for a couple hours, take to an auto parts store - most will test it for free. Although a load test can give a pretty good idea about the condition of your battery, a better test is to hook it up to a Conductance Analyzer. Your dealer is supposed to have one but I think I would feel better about taking it to regular battery dealer for testing..., or just bite the bullet and get a new, high quality AGM battery that has been properly prepped and charged!!

Okay i'll remove the battery this evening and charge it over night and take to autoparts store tomorrow. I happen to have a large AGM battery, I'll have to check the specs of the battery though. I'm sure it's too big for the Polaris. Is there a limit on the size of battery that the Ranger charging system can handle?

Took the battery to auto parts store and it checked out good. Took it to the Polaris dealer and they used that device and it checked out good. I guess after hunting season I'll take it in to get checked out. Just running the small light bar only draws .10 volt so i'll run it instead of it and the headlights. Which its brighter than headlights anyways so don't need to turn them on. Here's a short video I made the other night showing how much the headlights and the lightbar are drawing on the battery. The low battery indicator doesn't come on in this video, but it will after i leave both on and ride for about 10 minutes. Leading me to believe something is jacked up with the charging system.

I got a feeling your stator is capping out. There's no way you should be getting a low battery light with those both on. My little 500 stator was holding up to hids, light bar, and a 1000 watt stereo. I'd highly recommend getting stator checked. I'm sure if you have a meter there's a way to test. I'm not electrical savy so someone else on here will chime in on how to test

I do have a meter. Just need to know how to check the stator. Once i get this thing figured out, i'll bet a bigger lightbar too.

Clay, that is perplexing! LBR is right, you ought to rule out your stator. Unfortunately, there are a bunch of other possibilities! But you gotta start somewhere - here are the stator test procedures followed by a trouble shooting guide to the whole charging system (from the '11 800 service manual - I think yours should be the same);

I am sure you already have but double check the connections at the battery that they don't wiggle and lose their connection. Follow them both back to make sure the ground and positive final connections are snug. My battery was low on water and the connections were ALL loose. This was a problem before I put the toys on. Since then I got a group 24 deep cycle battery with 4 gage cables and put it in the tub under the seat. No more problems with the winch or the 50" light bar. I cut a piece of 3/8 plywood on top so I can still use the tub a little. I Made the cables long enough so I can take the battery in and out of the tub and not have to disconnect the battery.

Good luck brother Ranger
