DIAGNOSTICS CODES
The Amigo controller has a built-in diagnostic feature that will cause
the diagnostic light LEDs
(located on either side of the battery gauge)
to flash a numeric code indicating service issues to aid in diagnosis.
When indicating a service problem, the diagnostic light LEDs will
flash, hesitate for a moment, and then flash again. Follow the code
listings below to determine the problem. If the code indicates a
service problem, contact your local service representative or call the
Amigo service department at 1-800-248-9131 for instructions to
verify and correct the problem.
(1) Unplug handle cable and plug back in.
(2) Check all wiring connections and output.
(3) Disconnect brake and cycle key, if code changes to 1-2, replace brake.
(4) Replace controller.
(1) Ensure EM brake lever is in normal/drive position
(SmartShopper only).
(2) Unplug handle cable and plug back in.
(3) Check all wiring connections and output.
(4) Replace brake.
(5) Replace controller.
(1) Check motor wiring connections.
(2) Disconnect brake and cycle key, if code changes to 2-2, replace motor.
(3) Replace controller.
(1) Ensure EM brake lever is in normal/drive position.
(2) Check motor wiring connections.
(3) Replace motor.
(4) Replace controller.
(1) Check / replace batteries.
(2) Check / replace controller.
(1) Allow to sit idle for 15 minutes, restart and see if code disappears.
(2) Ensure EM brake and / or motor is not causing excessive amperage draw.
(3) Replace controller.
(1) Replace battery charger if voltage is 32 volts or higher.
(2) If 31 volts or lower, replace controller.
(1) Replace charger wiring.
(2) Replace battery charger.
(3) Replace controller.
(1) Replace controller.
(1) Replace controller.
(1) Check to ensure handle cable is in good condition.
(2) Check that throttle lever moves freely and returns to center.
(3) Replace throttle hall effect.
