TROUBLESHOOTING
The Amigo is equipped with an ASIC Controller. This Controller has a Built-In Diagnostic Feature that
will cause the Battery Indicator Light LED to flash a numeric code to indicate when there is a service problem.
Under normal operating conditions the Battery Indicator LED will flash to indicate three different situations.
1.
To indicate a low battery condition when driving.
2.
To indicate the battery charging cycle has started.
3.
To indicate when the batteries are fully charged during the charging cycle.
When indicating a service problem, the Battery Indicator Light 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 Authorized
Dealer or call the Amigo Service Department at (800) 248-9131 for instructions to verify and correct the problem.
