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 an 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 current and voltage that can burn you when a shorted circuit occurs. Be absolutely sure
you know what you are doing before trying any tests to eliminate a component from consideration
of being defective!!!
3. You can take the battery to a shop capable of testing the battery under a loaded condition. Fully
charge the battery and carefully remove it. Let a technician determine the condition of the battery
for you.
