If the lights on a the throttle are showing a full battery then try disconnecting the brake switches at the controller one at a time. If the bike works after disconnecting a brake switch then that switch is faulty and should be replaced.
There is some excellent information on trouble shooting and testing components here http://www.razorama.com/razor-installation-guides.html
also wiring diagrams here http://manuals.monsterscooterparts.com/recreational/Razor/Wiring/

SOURCE: The MX500 wont start. The light says the battery

Although you alternator may be charging, the battery may not be accepting the charge or holding it. Have the battery tested under load, but I think that you are going to find you will need to replace it.

It sounds like the throttle cable needs to be adjusted/connected. Check all the cables/wires going to your throttle.

I Replaced the charger port on my Razor Mx500 Dirt Rocket and it ran fine and then just stop. The charger still indicates the batteries are charge but no power. Also I went to check the fuses and manu

Well if it's missing fuses obviously it won't run. When you turn it on does the green light on the throttle come on? if you have a voltmeter that would help. Are you sure the charger is good? if so you want to see 39 volts or so across all 3 batteries. Sometimes the switch contacts develop excessive resistance try shorting them with your screwdriver... if it runs you need a switch. can you hear the controller click when you turn the throttle?

How long can the Razor MX500 Dirt Rocket be ridden after charged?

Run time depends on a few things, including the weight of the rider, the terrain being riden over and the condition of the bike.
For example, a light rider riding on flat hard packed dirt or paved road with a bike that is in good mechanical condition - tires inflated to correct pressure, chain correctly adjusted/lubed, brakes adjusted, etc. - will have a longer run time than a heavier rider on soft undulating dirt with a bike that has not been maintained.
Generally you should be able get 40-45 minutes out of a new battery.
Check out the trouble shooting guide and user manual if you are getting less than half and hour.

Why is my Razor motorcycle MX350 battery showing green but not charging

yes!your battery needs replacement.....throttle clicking after a full charge is a sign,...but that's after 2years or more,depending on how it's being used..your motor can go bad before then if you been riding in the rain--wet connectors in or out the motor can not get wet for any reason..a full dirt motor bike can not get full dirty with mud..mud catains water/water and electricity don't mix/////.motor/thottle/moisture.

My razor mx 500 motor won't turn.

I think you are talking about an electric motor on your bike . If the motor is New you may have a bad throttle switch . You can use an ohm meter to check the throttle switch . Connect the two leads of the ohm meter to the wires of the throttle switch ( dissconected) . As you turn the throttle the ohm reading should coraspond to how much you turn it .

The MX500 wont start. The light says the battery is charged but when I twist the throttle all I hear is a clicking noise. Is it possibly the fuse?

I just replaced the battery, but cannot get power. The "green" light on the charger stays on contstantly. what are the most likely reasons for this problem?

If you have replaced the 3 batteries inside and properly charged them overnight for 18 hours check to see if you have every connector plugged properly. IF you still have no power possibly the control modulator has failed. Is your throttle lighting up when you activate the switch? You can also check to see if the switch itself is working with a voltage meter. Leaving the bike outside in the rain can damage the MX500.
