what could be the cause of a short when I connect my ATV battery? I am worried this can blow my rectifier or stator. I checked both rectifier and stator with multi meter, they are working ok. when the bike is on idle and I remove the battery terminal, it goes off. Please help friends

 

You have something wrong with your stator ignition circuit if it dies when the battery is diconnected. You don't need a battery to run an atv, or even start it if it has a pull start or can be push started. All the power for the ignition/ spark plug comes from the stator while the engine is running. once the quad is running, you can take the battery out if you want, part of the stator charges it, the other part is power for the ignition system. Sounds like your ignition system is possibly shorted, you should not get a spark on your battery unless your key is on, or the starter circuit is shorted,or there is a wiring problem that is putting a drain on the power.

 

So where do you think I should check. The stator and the rectifier are brand new. After I installed them everything was ok when I took a test drive, now today I connected the battery I got this spark and when the engine is running and I take off the battery terminal, he engine goes off. I am not sure where to check. Please help

 

Electrical is not my strong point, I just know the basics, and without knowing the make of your quad, hard to say. why are you disconnecting the battery to test things? how is it running that led you to wanting to disconnect the battery while its running? what are you checking for? How big of a spark are you getting from the battery, a little static spark, or a big sharp arc? if you are getting a big arc, you have a short, and need to get a wiring diagram to find out what could be causing it.

 

it is a 2011 Kawasaki 750 4X4 Brute Force. my reason to check all these was that I was getting a long and hard start. the spark is not big. it sparks and then stops, but am wondering why it goes off when taking out terminal because its not supposed to do that.

 

Check your voltage regulator.

I am not an expert- I work on outboard motors, but VR's are usually the first thing to go. If you don't change them, often they blow up more important stuff.

Of course, you might want to listen to someone who actually knows these machines, but you asked for suggestions.
