Hey guys, any help would be great....a little background. My neighbor lady, told me to come over to her barn she had something for me. Turns out it was her and her husbands (he passed about 2 years ago) atv. Now I have only ever owned a honda atv so I am a Polaris newbie. its a 2004 (built in November 03) Polaris sportsman 700 twin carb model. Its the cammo model with a factory warn wench. Now I remember her riding it a few years ago but other than that don't know much about it. She told me it was serviced every year at dealer. So it has set for 2 years so obviously I figured it would need cleaned out and carb work. Just for kicks and giggles since it still had half a tank of fuel I hooked a set of jumper cables up to it and gave it a whirl.....it fired right up on choke but as soon as I would push choke it it would immediately die, or as soon as I would take the jumper cables off. So I figured ok main jet or needle needs clean and a new battery! I ordered a brand new battery, added the acid and trickle charged it until it was 100%. I cleaned the carb and wanted to see if it would work, so the next day I plopped the new battery in it and tried starting. It fired up and ran a little better but still wanted to die off choke. I tried starting it again and this time the instrument lights barely came on with a click sound. turned it off and tried it again and 3rd time it didn't even light the instrument panel lights up. I had a set of cables handy so I immediately hooked it to my car ( I know bad, but just wanted to see if it was battery or something else.) and I had power again...so my question. what kind of drain should I be looking for that can smoke a battery in a matter of minutes????? Please help

A 'trickle' charger can damage a battery and occasionally the battery is bad from the factory. Get a replacement battery, get the correct battery (not a cheap Rex battery or Battery Specialists unit). Fill the battery with the correct acid (if not included with the battery) - let the battery stand for at least 15 minutes before connecting to the charger for the activation charge and do not exceed a charge rate above 10% of the battery's 10 hour capacity.

From the Yuasa Battery activation guide:
For batteries with ratings of less than 18 AH, let the battery stand for 20 to 60 minutes. For batteries with higher AH ratings or having the High Performance rating (designated by an “H” in the part number/name), allow the battery to stand for 1 to 2 hours. Yuasa AGM batteries have amp hour (AH) printed on the front of the battery case. The stand or rest period allows the electrolyte to permeate into the plates for optimum performance.

Newly activated AGM batteries require an initial charge. After adding electrolyte, a new battery is approximately 75-80% charged. After the “stand” period described in step 6, charge the battery to bring it to a full state-of-charge. The battery charger used for initial charging should be able to charge at 12.8+ volts for an AGM battery.

The new battery I purchased was a YUSK....about a 90 dollar battery, so probably not top of the line but there were some cheaper ones. I added the acid supplied with the battery and did let it set for a while after added. The instructions told me on the initial charge to not charge any faster than 2amp. so I used a trickle. With the positive cable hooked up and a tester on the ground and grown post I am showing a high draw, but I am having no luck at finding it. I am also having a no idle issue. I cleaned the carb, found a clogged main jet, cleaned and installed but still the issue, would that be related at all in some sort or fashion?.....I will have battery checked out if it could be bad. Thanks for help!

If you've got a voltage draw like that you'll need to start unplugging stuff till you find it.
Winch, extra lights, hand warmers etc.
If you can get to it easy I'd try unplugging the VR first though.

What amount of draw exactly - Just a single spark as the ground wire is connected or a measurable 1 amp or greater continuous draw? See what you have to unplug or disconnect to get the draw to go away. Note: the speedo will place a very low (perhaps less than 1/10 of an amp) draw on the battery and the rec/reg will place a momentary draw on the battery as the capacitors in the unit charge to battery potential.

Power goes from the battery to the rec/reg, to the power outlet plug, the speedometer and the key switch - with the switch off, the only things that can draw on the battery is the rec/reg, something plugged into the power outlet and the speedometer. If the speedo and rec/reg is unplugged and there is nothing plugged into the power outlet, the only there can be a power draw is if there is a short in the wiring or another aftermarket accessory is improperly wired into the system.
