Troubleshooting: No Power
In this situation we will assume that the battery has been charged or allowed to stand for
several hours (a battery will normally self-charge up to a point and make the scooter power
up for a fair distance). There are generally two main suspects:
1. First suspect a loose or broken connection. Take the top or deck off to see the wiring and
inspect it for any loose or broken connections on the battery, switch, controller, etc.
2. Second suspect the controller box has failed. Since the controller is the heart of the
system it can fail in many ways to prevent current from being supplied to the motor.
3. Other less likely suspects can be: A battery that is completely open, supplying no current
and possible even testing as having no voltage. It can be very briefly shorted with a wire to
see if an arc is produced, revealing current is present.
It is also possible to have a bad brake lever or throttle since both have wiring and switches or
variable controls. The brake lever has a power cut-off switch. The throttle variably controls
the speed of the scooter.
The scooter On/Off switch can be defective. Without a good switch the scooter has no power,
but the test of this is the power light. Does the power light come on when the switch is
activated to the on position?
Troubleshooting: After Fully Charging, Powers Only For Short
Distance Use
1. Suspect the battery charger or the battery as the primary cause of short distance riding
after a lengthy or full charge. If your battery charger does not have charging indicator lights
then you may not be charging the battery at all if the charger is defective.
2. The battery may be self-charging to only about 60% on its own. If the battery is getting old
then it may not be able to hold a full charge and the battery will need replacement. When
suspected you can very briefly arc across the battery terminals with a insulated wire to see if
it produces a nice arc. . It is also possible to test some individual battery 12 volt cells using
12 volt motors or lights that will show you the available current capability. Is the 12 volt light
dim on a charged battery? Does the 12 volt motor run slowly when connected to the cell?
Similar type tests can be performed using a 24 volt battery cell, too.
WARNING! Batteries contain acid that can explode, or the vapors ignite from an arc. Batteries produce
