Hello all need some help, The battery in my sled keeps going dead. What should I be looking for? I put a new battery in it end of last year just thinking it was time for a new one. (The old one was dead too!!) Went to start sled early this summer and it was completely dead. I remember my brother siscakid having the same problem on his warrior before he traded it in. He never figured out what it was.

well to start with give it a jump start then take a multimeter & measure the voltage off the battery with it running to see if its charging. this should be your starting point of your trouble shooting. I think it shoud be putting out 14+ volts running you can test from the jump start cables that stick out the right side by the oil tank. Hope this helps

I would buy a optimate 3 or 4 or another charger that desulphates the battery to bring it back into shape.

I agree with checking the charging system.
Keep in mind, all batteries will self-discharge, some more, some less, but they all do it.
If you leave it un-attended, eventually it will run down and start sulfating the plates.
Read a study by a battery manufacturer that every time you run a lead-acid battery dead, you loose half(50%) of the remaining life.
That's a BIG chunk to loose.
(If you run it WAY down, the cells risk reversing polarity, instantly killing the battery.)
Best bet to make your battery last is use a battery tender over the summer while in storage.
(A month of non-use is a long time to most batteries.)
A battery tender costs about $5 from Harbor Freight.
Much cheaper than replacing batteries.
Hope this helps!

Also check the wiring in the nose of the sled under the tool box that is where I had my problem with the battery dieing.

Thank you, I'm going to start my search tonight. I will let you know what I find.

To see 14 VDC, you may have to rev the sled a bit. I typically see ~ 13 VDC at an idle of 1600 RPMs. This also implies that your battery is fully charged. The sled can not fully charge a dead battery.
Speaking of charging, ... The battery should be charged monthly during periods of non-use. An Optimate IV is ideal. Battery Tender will also work well. But the trick is to put it on monthly. Actually, with these two units, they can be put on and left on, if you just can't seem to remember to do the charge monthly.
If you do not see that voltage at >= 13VDC, then you are into trouble shooting the charging system. Please let us know how you make out with this one.

Update: could not find anything wrong so off to the dealer it went. Lets see what they find.
One thing I did not mention is my son knocked the high/low button off. could that cause my problem????

my high/low is knocked off from my nephew also, will not affect anything. Good luck, I had the front rub through problem on my 03... very common as stated prior. think snow!

If you leave the stop button on or the key it will kill the battery over a few weeks .

Just to recap this Thread: Batteries loose significant charge just sitting over the summer. They need to be charged ~ monthly. An Optimate charger is perfect for these batteries. Sometimes, the Optimate can even partially recover them. But once you let one go dead over the summer, the battery will most-likely not last long, even if it is recovered.
The sled can not recharge a dead battery. Jumping the sled to start it and thinking the sled will fully charge the battery is a pipe-dream. Fully charge the battery. Then install it and the sled will keep it charged. There simply is not enough power generated and not used to charge a fully discharged battery.
At 4,000 RPM you should be seeing > 13.8 VDC at the battery with it fully charged. If you are not seeing that, then some troubleshooting is in order. With the sled off, a fully charged battery will read about 12.2 VDC after it sits for an hour.
