About the Alante DX/LT Service Guide
This service guide provides you with the information necessary to troubleshoot the Golden Technologies Alante
DX (GP204) and Alante LT (GP215) equipped with the PG VR2 controller. The troubleshooting scenarios in
this manual consist of procedures that enable you to systematically trace and correct faults in the system.
Before troubleshooting, check the following:
• Make sure that the circuit breaker is reset.
• Visually check terminals for corrosion. Check wires for missing insulation.
• Make sure that the batteries are fully charged and in good working order. When possible, keep sets of
known good batteries of various ratings in your shop at all times. The Alante DX uses 22AH batteries
and the Alante LT uses 18AH batteries. Problems that surface during troubleshooting are often due to
the fact that the batteries are not fully charged or can not hold their charge.
• Make sure that the electrical connections are secure. Unplug the connectors and make sure all of the
pins are seated properly. Push the pins back into the connector housing if necessary. Make sure that the
battery terminals are tight.
NOTE: If you get to a point during troubleshooting where you cannot continue, call tech support at
800-624-6374.
