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.

Scenario 1: Turn the Key to the On Position and No Power
Put the key into the key switch and turn to the on position. There is no power to the control panel. The horn
does not work, the lights do not work, and the battery condition meter does not work. Battery voltage travels
from the batteries, through the controller and the key switch. The test below will verify that there is battery
voltage at the batteries, the controller, the main harness, and the key switch.
Check Battery Voltage
1) Remove the seat.
2) Remove the battery cover.
3) Measure voltage across the terminal with the red wire on one battery and the terminal with the black wire on
the other battery.
• 24VDC (or battery voltage?) - Go to the next step.
• More than 16VDC? - Try to recharge the batteries. Load test and replace if necessary.
• 0VDC? - Check the battery fuse for continuity. Replace with 125A fuse if necessary. Check main circuit
breaker (1) and main power harnesses for continuity (6a to 6b/6c and 7a to 7b/7c.) Replace as necessary.
Check Voltage at Controller
4) Unplug the power harness from the controller. This connection is marked with the symbol. Measure
the voltage across the red and black wires.

Scenario 2: Batteries Will Not Charge
Most battery chargers need to "see" least 16VDC at the charger port. Otherwise, they may not send a charging
current to the batteries. This test will ensure that the battery voltage is making it to the charger port. You will
need to check battery voltage at the batteries, at the controller, out of the controller, and at the charger port.
Check Battery Charger Voltage
1) Remove the seat.
2) Remove the battery cover.
3) Plug the charger into the charger port and then into a wall outlet.
4) Measure voltage across the terminal with the red wire on one battery and the terminal with the black wire on
the other battery. Does the voltage increase?
• Yes? - Load test the batteries and replace as necessary.
• No? - But there is voltage. If the voltage is lower than 16VDC, then replace the batteries. If the voltage is
16VDC or greater, then go to the next step.
• No? - And there is no voltage. Check the circuit breaker, power wire harness, battery harnesses and their
fuses for continuity. Replace the individual components as necessary.
Check Voltage Into the Controller
5) Measure voltage across the B+ (red wire) and B- (black wire) of the power harness. This is the large black
connector on the controller marked with the symbol.
• 24VDC (or battery voltage?) - Go to the next step.
• 0VDC? - Check circuit breaker and wire harnesses for continuity. Replace as necessary.
Check Voltage Out of the Controller
6) Insert the multimeter probes into the terminal with the red wire (pin 7) and the terminal with the black wire
(pin 13) on the back of the main harness (14-pin) connector. Refer to the wiring diagram on page 27.
• 24VDC (or battery voltage?) - Go to the next step.
• 0VDC? - Replace the controller.
Check Voltage at the Main Harness
7) Remove the front basket bracket.
8) Remove the front tiller shroud.
9) Disconnect the charger harness (red 3-pin connector with a red, green, and black wire) from the main harness.
10) Measure voltage across the two outside terminals, a black wire and a red wire on the main harness connector.
Refer to the wiring diagram on page 27.
• 24VDC (or battery voltage?) - Go to the next step.
• 0VDC? - Replace the main harness.
11) Check the charger harness fuse for continuity.
• Continuity? - Replace the charger harness.
• Open? - Replace the 15A fuse.

BEEP CODES
The S-Drive controller uses audible beeps to indicate the status of the system. When the controller notices that
there is a malfunction in the system, it will beep a code when the power is on. The signal will be a set of fast
beeps lasting two seconds. The slower diagnostic pattern will then be sounded once. For example, when it
Beeps five times and stops, that indicates BEEP code #5 – Brake Trip.
The following BEEP codes are used to help diagnose system errors:
BEEP Code #2 – Low Battery Voltage
BEEP Code #3 – High Battery Voltage
BEEP Code #5 – Solenoid Brake Trip
BEEP Code #6 – Throttle Trip (Out of Neutral)
BEEP Code #7 – Throttle Trip/Speed Control Fault (Voltage Error)
BEEP Code #8 – Motor Disconnected
BEEP Code #9 – Possible Controller Trip
BEEP CODE #2 – LOW BATTERY VOLTAGE
The batteries need charging or there is a bad connection to the batteries. Check the connections to the batteries.
If the connections are good, try charging the batteries. If the batteries will not charge, load test them or refer to
“Scenario 2: Batteries will not Charge.”
BEEP CODE #3 - HIGH BATTERY VOLTAGE
An excessive voltage has been applied to the S-drive. This is usually caused by a poor battery connection.
Check the battery connections. NOTE: The error may only be present when going down hill and power goes
back to the batteries.
1) Insert the key into the key switch and turn it to the on position. Allow the battery level to drop. Do not allow
the battery voltage to fall into the red area on the battery meter.
2) Check the battery charger. Make sure it is an approved charger.
