I've replaced the batteries and charger and charged for 12 hours but the device still just clicks when I turn the throttle any more suggestions?

i love u.

I need help! My son mx650 is charged, but won’t run. Put weight on it won’t move but lift rear tire off ground and runs full throttle

Sounds like a defective unit. You've tried everything their support people would walk you through.
Sorry...

1.Check the device's battery level for at least two bars of strength.
2.If the battery level is low, charge the battery.
3.If the issue is not resolved, remove the back cover.
4.Remove the battery.
5.Wait 10 seconds.
6.Press and hold the W key.
7.While pressing down the W key, re-insert the battery.
•The device restarts and after approximately 15 seconds, the 'Recovery' screen appears
•Release the power button but *continue holding the home button*, for another 30 seconds.
Step
Thanks

sounds like the battery is bad and not taking charge.replace battery attemp again if not then check for fuel, spark and compression.then c wat happens or wats not working any motor no matter how small or big has to hv those three things to run. hope this helps.

I had the same problem with the P10 not charging via USB, I purchased mine second hand so it came with no charger. I assumed it would charge by the USB cable but it did not, the red light flashes but doesn't charge. Luckily I have an external battery charger for a different camera i got some years ago that takes a similar battery , the P10 battery didn't fit properly so I had to place it at a 45 degree angle into the charger making sure the outer contacts were lined up properly and taped it into place. After an hour it was fully charged and the camera is working fine. The charger is a 4.2 volt charger. New external chargers can be picked up on ebay cheaply

If you hear the starter relay click, but not turn over the motor that's a classic low/dead battery situation. There is only enough power left for the battery to click the starter but is not powerful enough to actually turn the engine over.

three ways you can deal with this issue.
First replace the battery.
Second give the battery a charge using either a battery charger or the more common battery trickle charger (battery tenderizer) which most motorcycle owners use to keep their bikes battery charged over long periods of non use like the winter. If you have a tenderizer just hook it up to the battery, plug it into the wall and let it trickle charge for about 12-16 hours or so and then try again.

If the starter is actually turning over but you arent gettting the engine to fire then it has to be one of the only two remaining variables that we need for combustion, spark and fuel. check you spark plugs for excessive wear, carbon buildup or damage, and then check the spacing or just replace them. if you see a spark when you fire the starter than its not a plug issue.

Finally fuel. Is there gas in the tank? can you hear the fuel pump click on once you turn the key to on? is the line creased or corroded, if you unplug the line do you see fuel being pumped in?

those are your three possibilities.

Another easy thing to try to check if it is a batteyr issue and you don't have a charger is to try push starting the bike

1. First, make sure that your bike isn't starting just because you are out of gas. If you're out of gas, this will not work.
   
2. Make sure the key is in the on position
3. Put the bike in 2nd gear
4. Hold the clutch in and begin pushing, preferably downhill, but it will work elsewhere as well.
5. Once you've gathered enough momentum, apply a minimal amount of throttle (not too much or the bike will get away from you) and hop on the bike just as you release the clutch.
6. Rev the engine a bit so your bike doesn't conk out.
7. Ride away.

Assuming there is power at the cigarette lighter jack - turn the Nuvi off - then connect the charger. It should display charging battery or charging complete.
If nothing - does it charge with the wall charger? If so check the fuse in the car charger - it's usually in the tip of the charger which can be turned to get the fuse out.

Is the AC Power adapter the original adapter of the laptop? If it is, try to drain the battery and charge it for 8-12 hours without using or opening the laptop just charge it. After charging, remove the power adapter as you open your laptop. Make this way a habbit of using and charging your laptop to make the charging and battery life last long.

We had the same problem that I found to have a very simple fix. It seems all that needed to be done was hold in the reset button a few seconds while the battery charger was plugged in and the light on the charger turned to red and the battery charged again. Seems like too easy of a fix but it worked for my kids scooter.
