My roketa atv keeps draining the battery,or the battery is not charging. I'm not sure which. I'm not the best mechanic in the world. Hoping somthing I can do with money being so tight right now. Thanks for any help

 

Welcome to the forum kerlo2009 !

Do you have a Volt meter? If you dont..go buy a cheap one and while the quad is running check the volts being produced...is it over 12.5? If not rev the engine a bit..do the volts increase? Should be over 13 volts at approx 2000 rpm...If it is the battery is shot....if it isnt then youve got a charging problem.

 

thanks for your help. charged the battery. atv started unhooked the battery atv still ran,so i'm guessing it's not a charging problem.

 

The Chinese batteries are junk usually so just go down to the store and buy a new one. Having said that out of my four Chinese Jetmotos two of my batteries lasted 2 months the other two has now lasted 3 riding seasons, go figure!

 

I bought a 150 and 200 at the same time two years ago. One lasted one year, the other went out at two years. Money is tight all around but 25 bucks for a battery from Walmart is not too painful.

You can always jump start it if you need to and park it on a slope when you stop so you can do a rolling bump start if you are not near another battery. The things draw so little current you can use pretty small wire (10-12 should be fine) to make a set of short jumpers, you sure don't need anything near a car battery wire gauge for an ATV.

One other thing is to disconnect battery after ride and if it won't start up after a day or two the battery for sure is done.

 

The ignition system runs off its own high voltage AC power supply generated in the stator. The 12 volt battery and battery charging system are a completely different system. Its only purpose is to run the lights and turn the starter motor.

Your observation that the quad runs with the battery disconnected does not tell you anything about the charging system. As MWQ said, the best way to test the charging system is with a voltmeter. They are not expensive. I saw them as Harbor Freight this last weekend for $2.99.

It may well be that your battery is toast since leaving a battery discharged (or even partially discharged) over time wrecks it. Since money is tight you don't want to change out the battery without testing your charging system. Otherwise you might just run the new battery down and over a period of a few weeks destroy it too.
