DIAGNOSTIC CODES
The Amigo is equipped with a microprocessor controller. This controller has a
built-in diagnostic feature that will cause 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 (800) 248-9131 for instructions to verify and correct the problem.
**Note:
First solution listed for each diagnostic code will fix that problem 80% of
the time. Attempt solutions in the order listed.
