ABOUT THIS SERVICE GUIDE
This service guide provides you with the information necessary to repair the Golden Technologies Patriot
scooter. There are two parts to the service guide: Troubleshooting and Component Replacement. The
Troubleshooting section will assist you in finding the source of the problem. The Component Replacement
section contains step-by-step replacement instructions for key components.
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 in good working order.
When possible, keep sets of known good batteries of
various ratings in your shop at all times. The GR575 requires 75AH batteries. Problems that surface during
troubleshooting are often due to the fact that the batteries are not fully charged or cannot 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.
If you get to a point during troubleshooting where you cannot continue, call tech
support at 800-624-6374.
