Need help 400ex .please. No juice

[bluvette28]

HI,

I have a 2000 honda EX and my quad has no juice. IT will start if i hook up a charger but not even to the battery im not sure what its called my postive connection leads to it. Its round and has another wire going into it maybe the ignition not to sure. The battery is a month old my freind hooked up the postive to negative and negative to positive the other day will that kill anything. Thats when the problem started. Ive also been riding it in the snow that day before he was an idiot and did that. It will also start if i roll it down the hill and dump the cluth. Please help me i am so lost on this. Thank you

no the positve was hooked up to the negative and the negative to the positve and the fuses are checked there not blown. Im not sure about the round this its right above my battery i have the aluminum performance airbox there both in there and its a small round thing that has a postive lead that goes right down to the battery maybe the ignition coil not sure.

Your battery was probably shorted out. You shouldn't cross terminals. What's happening is that your battery is no longer holding a charge but is completing the curcuit after started with your charger, to keep it running.

I believe you have a Yuasa YTX9-BS battery in there.

Just a tip, instead of going to the delaer for a new battery, try going to a Sears Auto to pick one up: Shop for PowerSport batteries in the Automotive department of Sears.com

I've attached the starting and charging systems wiring diagrams for you.

You could have screwed up a lot of things. So the battery is hooked up correctly now? What happens when you push the button, any noises? If you hook up jumper cables and push the button, what happens?

BluVette and ATVmechanic, welcome to the site. Enjoy!!!

If i hook up the cables to the battery and hit the button it doesnt work. Every since two nights ago when my freind hooked up jumpers to the wrong terminals. If teh cables are hooked to the battery and i hit the button i get nothing at all the lights dont even work.

welcome to the site ATVmechanic we definitely could use u around here lol....bluvette u should get a new battery first of all and im still not understanding wat that thing is above that your talking about... just make sure everything is hooked up were it is supposed to be when u get the new battery cause the one u got now is shot

[Stoopidbot1]

You fried the battery, and possibly something else.

[outlander560]

worst case scenario ur starter is shot

So i was workin on the quad for alittle while today and i guess i didnt tighten the bolt on the battery bracket to the bottom of the aftermarket box and i wasnt getting a good ground it was fine until two days ago but i guess it got loose from riding. Just put lock tight on it and its running strong. Thank you for all the help

clean all the terminals first and check all the connections! batteries are not cheap, make SURE it is the solution, happy to help if needed.

Sounds like you lucked out! Need to have a good ground. Good job.

If it sounds like it's trying to turn over but can't, change out your starter. Mine had a brand new battery and still seemed as if the batter was low or dead, I changed out the starter and it fired right up.
