Troubleshooting Guide

Problem

Possible Cause

solution

Vehicle does not run

Undercharged battery

Charge the battery. A new battery should have been charged for at

 

 

least 12 hours before using the vehicle for the first time and up to 8

 

 

hours after each subsequent use.

 

 

Check all connectors. Make sure the charger connector is tightly

 

 

plugged into the charging port, and that the charger is plugged into

 

 

the wall.

 

 

Make sure power flow to the wall outlet is on.

 

Charger is not working

You may check to see if your charger is working by using a volt meter or

 

 

asking your local Razor authorized service center to test your charger

 

 

for you.

 

Loose wires or connectors

Check all wires and connectors to make sure they are tight.

Vehicle was running but

Burned-out fuse

suddenly stopped

 

Motor or electrical switch damage

The fuse will burn out and automatically shut off the power if the motor is overloaded.

An excessive overload, such as too heavy a rider or too steep a hill, could cause the motor to overheat. Replace the fuse with a new one of equal amperage. Correct the conditions that caused the fuse to burn out and avoid repeatedly burning out fuse.

Contact your local Razor authorized service center for diagnosis and repair.

Short run time (less than

Undercharged battery

30 minutes per charge)

 

Battery is old and will not accept full charge

Charge the battery. A new battery should have been charged for at least 12 hours before using the vehicle for the first time and up to 8 hours after each subsequent use.

Check all wires and connectors. Make sure the battery connector is tightly plugged into the charger connector, and that the charger is plugged into the wall.

Make sure power flow to the wall outlet is on.

Even with proper care, a rechargeable battery does not last forever. Average battery life is 1 to 2 years depending on vehicle use and conditions. Replace only with a Razor replacement battery.

 

Brakes are not adjusted properly

Refer to brake adjustment instructions on page 5 of this manual.

 

 

 

Vehicle runs sluggishly

Driving conditions are too stressful

Use only on solid, flat clean and dry surfaces such as pavement or

 

 

level ground.

 

Tires are not properly inflated

The tires are inflated when shipped, but they invariably will lose some

 

 

pressure between the point of manufacturing and your purchase. Refer

 

 

to instructions on page 4 and 5 of this manual to properly inflate tires.

 

Vehicle is overloaded

Make sure you do not overload the vehicle by allowing more than

 

 

one rider at one time, exceeding the maximum weight limit, going up

 

 

too steep a hill or towing objects behind the vehicle. If the vehicle is

 

 

overheated, the temperature circuit protector will slow motor down

 

 

and if the condition continues, will shut off power to the motor. Correct

 

 

the driving conditions that caused the overheating, wait 5-10 minutes

 

 

and then resume riding. Avoid repeatedly overheating the unit.
