I have an Electric Razor ATV that I am having issues with. It is showing fully charged but will not go. I have checked the fuses, put a new throttle and computer module in it. I am showing 20 amps to the rear motor. I have lifted the back and tires turn about 1 inch and then stop. There is no grinding or noise at all. Any info or other trouble shooting ideas would be great. Thanks

Question edited for clarity.

Get out your multimeter and check the TOTAL voltage. You should have 24 volts or 36 volts depending on model. If you don't, take them all of and charge each one on a car charger set at 2 amps. Clean all the battery connectors with a wire brush and also the connectors. Smear them with Vaseline. Also make sure you have the batteries wired in correctly. If don incorrectly, you may be running on 12 volts!

It has an electric motor I would check the sprocket on the motor see if it has a key way it could of broke or fell out

power wire and ground make starter work inside starter case. the power wire goes through several safety switches on way to starter. check each connector 4 loose wiring. battery (-)to engine and frame need more history here b4 i can help anyymore. good luck

the charger probably has a meter on it, you can check voltages with it. remember that the battery connectors must be tight, but don't break them.

take a OBD2 scanner to have check, maybe you will know what is problem.

Sounds line the stater motor gear is stuck on the fly wheel. Have a mechanic check it just to be safe.

replace relay.. and clean all terminals at battery and fully charge battery

Check the ignition switch it self. Or the starter relay, it may need replacement.
