everything was fine on my 450r today, started fine lots of juice, but when i got to my friends, just down the road it woulnt start after i shut it off. it will sart with the battery charger but the battery wont charge. Im going to leave a charger on it tonight and see what it does but i think the battery is fine. What else could go wrong, does the voltage reg effect this at all?

 

Well what I would suggest is charging it, but don't overcharge it and make the battery get hot...Also make sure it is off of the concrete or you will lose the charge...There can't be any fuses blown as you did start the quad and the cables should be fine so just check out the battery and if the battery doesn't work I would start looking elsewhere like the stator and rectifier etc.

 

if the stator is screwed will i still have power when the quad is running? Cause right now there is light comming from the headlights and neutral light its just very dim. I know when the stator went in my sled my spark timing was all messed up also but this might not be the same on quads

 

the battery wont even charge on the charger, so it must be toast. I was just wondering how it would go all of a sudden

 

Who know I guess it depends on how much you ride and if you overcharge the battery with a charger and get it hot it will ruin the battery so I would recommend a battery tender and hook it up after every ride and it will last much longer...If you have a multimeter do some testing and make sure the battery it totally dead, but it sounds like this is your problem.

 

I am suprised that the engine was not breaking up in the power range running on a low battery.
I have seen batteries go bad when there is a draw on them that pulls them down so low that they reverse polarity.
A simple test use a Volt meter to see if the polarity is reversed.
If it is not taking a charge at all with a battery trinkle charge overnight then it is in bad shape.
But when you do get a new one double check the charging system, there still may be something there to verify so you do not lose another battery.

With the engine off.
Remove the fuse and replace it with ammeter * make sure the leads are protected from shorting out on anything during running especially.
Set it on DC amps to its highest setting.
Start the engine
Work the settings backwards to a lower setting that registers optimum current flow. This is to safe guard the meter and its inline fuse if it has one.
Revve the engine and see if the current fluctuates in the positive direction.

* I believe that the positive red wire of the meter will go to the positive of the harness and the black wire negative side of the meter goes to the positive of the post of battery. This will show that the charging potential should be higher than the battery potential.
Doing this test the battery must be better than 75% of its full potential.

If there no fluctuation in the positive direction then I would suspect the rectifier since the machine was running with a low to dead battery.

 

I was going to suspect he had a charging problem until he mentioned that the battery wouldn't charge at all, but he may have 2 problems built into one not sure until he gets a new battery puts in acid and charges it up...Give us an update kyle when you get the battery all charged up, but be careful putting the acid in if you have to.

 

This is a totally sealed battery. When purchased from Honda, no filling is needed. They are shipped already filled and charged.

This type of battery needs a special kind of charger. Recharge on it needs to have a battery charger that will put out around 24 volts and low ampres.
Automotive chargers , even if it has 200 amp boost will not dump 24 volts into the battery. If an auto battery charger is used, the high amps will heat up the plates inside the battery and warp them so they will short together, or fry the plates off a negative or posative rail inside the battery.

Honda has the correct battery charger available for these batteries available for the consumor. They are around $60 and well worth the investment. It is a High voltage low amp charger. It will not cook the battery like an automotive one will

He probably has no charging system failure, prolly just a loose battery cable end let the quad unable to charge all the time.

Remember, A quads charging system will not replentish a dead battery.

Does Honda use a yuasa battery or their own because I had to fill mine with acid then charge it for I believe 10 hrs and then could put it in on my ds650? I was guessing you would have to put the acid in because the battery's I got the caps were off and had to fill it and charge it with the caps off...He said the battery wouldn't charge with a reg charger and tol him keep an eye on it making sure it didn't overheat, but not sure how he made out with the battery.

You may be correct but it is better to double check for piece of mind, and to avoid a potental disapointment away from his repair shop/garage.
He did mention he had riden it to his friends house and did not mention the engine was breaking up or sputtering.
This lead me to believe the battery cables and grounds had to be secure and ran on what little the system is putting out.
Maybe you are correct BUT... leave no stone unturned
