Proper Charger
Use and Troubleshooting
Install the charger in a protected
location
Do not directly expose the charger
to the elements
Always switch car to TOW position while charging to
prevent damage to Motor Controller Unit
Do not install the charger in a location
where it will be directly exposed to rain
and wind. If exposed
to the elements, the
charger circuitry may
fail.
Inspect the plugs and
receptacles for damage
Symptoms of DC plug or
receptacle damage
•The charger fan runs
continuously.
•The POWER ON LED lights up
but charging does not initiate.
•
•Charging starts but stops quickly.
Inspect and Clean
If the DC plug pins are dirty
or bent, a contact failure or
a charging error may result.
Inspect and clean both the
pins in the charging handle
and the receptacle of the
car. Use a clean, soft cloth,
cotton swab, and electrical
contact cleaner to clean dirty
connectors. Replace DC plug
if pins are bent.
Charger location should
protect the cords and
charger from damage
The charger may fail if it is
dropped. Secure the charger and
cords to prevent damage.
Damage is not
covered by
warranty.
Check AC power cord connection
and circuit amperage
Plug Mouth
A dedicated15A circuit is required for each
charger. If the current capacity is not
the charger may not operate. Use the
Make sure power plug is securely inserted
into the receptacle.
Receptacle
Confirm battery condition
Over time/use, batteries will deteriorate. The
charging time will increase and the batteries
will use more water.
If batteries are in poor condition, an error may
occur during the charging process.
MAX
MIN
Routinely check the fluid level and specific gravity (SG) of batteries
Symptoms for
deteriorated
batteries
•Charging process stops quickly.
•Red power LED only. (Charger does
not go to green LED after charging
process).
•Battery charging does not end.
(Battery may be excessivley hot.)
