My razor mx500 is not starting the motor works and battery is charged it just doesnt start up when i turn the throttle

Thoughts -
No/poor connection between power source and motor
Motor failure
Only someone with their hands on the bike can fully diagnose.

Most likely, the last 2 answers are correct. When you charge the battery, does the light on the charger stay red for several hours before turning green? Check the voltage of the 3 batteries after the charger light turns green. It should be 39-40 volts or so no load. Turn the throttle and see if the voltage drops when the relay clicks. You can connect the batteries directly to the motor and it should go full speed if they are good.

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

yes! if that's the case ,the motor is the culprit.there are 4 things that make our bike run..the a good charger, batteries, the throttle, and the motor. now that you singled out your battery and charger ,you have the throttle and your motor..1st check your throttle & make sure it stops @ a1/4 twist.check all connections, then do an extencive check of your motor for moisture or water/signs of it being wet/riding in the rain..which is a big No-No../no rain No snow, No drizzle,and no puddles clean or muddy..it is not a gas bike....remember!great tip!

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.

Get a automotive battery charger that has 10 amps and hook it up to the motor. If the motor spins the motor is good. Just had to do this myself. Thought the motor was bad on ours and tested it found out it was good. Good Luck!

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 .

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.
