Scenario 2: Batteries Will Not Charge (Linx Charging Test) - Golden Technologies Compass Sport GP605 Service Manual

SCENARIO 1 - Continued
12. Check continuity across the circuit breaker wires of the power harness and across the battery wires of the
power harness. Repair or replace the power harness as necessary.
13. Check continuity across both the front and the rear battery harnesses. If open, check in-line fuse and replace
fuse or harness as necessary. Fuses must be replaced with exact type and rating.
Note: When checking continuity, visually inspect wires, connectors, and pins for any damage and to make sure
the pins are seated properly in their connectors.

SCENARIO 2: Batteries Will Not Charge (LiNX Charging Test)

NOTE: Battery chargers will not charge the batteries unless the battery voltage is 18VDC or above and there is
a closed circuit between the batteries. The circuit breaker completes that circuit. Make sure that the circuit
breaker is reset. If necessary, use a set of known good batteries.
1. Make sure the AC wall outlet the battery charger is plug into is not controlled by a light switch, causing the
battery charger to be turned-off inadvertently.
2. Remove the seat and the battery box covers.
3. Make sure that the batteries are connected according to the battery connection diagram on the inside of the
battery cover and/or figure 7 on page 13. Check the batteries and cables for corroded or loose terminals. Clean
and tighten if necessary.
4. Measure voltage across the rear battery negative (black) terminal and the front battery positive (red) terminal.
• Less than 18VDC – Load test and replace batteries as necessary.
• Greater than 18VDC – Go to next step.
5. Plug the charger in. Does the voltage reading increase?
• Yes – Greater than 24VDC – the charger is working – Go to the next step.
• No – Replace the charger.
Note: The charger must be plugged in and turned to the on position to perform the testing procedure.
6. With the charger plugged in and turned on, unplug the power harness from the power module. Measure
voltage across the pin 1 (+) and pin 2 (-) on the power module.
• Greater than 24VDC – Test the power harness for continuity and replace as necessary.
• 0VDC – Go to the next step.
Prevent damage to the (LiNX) power module. Do not allow the meter leads to touch each
other while taking the meter reading, which will cause a short circuit.
7. With the charger plugged in and turned on, reconnect the power harness to the power module.
Disconnect the bus cable from the power module. Measure voltage across pin 1 (-) and pin 4 (+) on the bus
cable.
• Greater than 24VDC - Replace the power module.
• 0VDC – Go to the next step.
8. Reconnect the bus cable to the power module. Disconnect the bus cable from the joystick.
Measure voltage across pin 1 (-) and pin 4 (+) on the joystick.
• Greater than 24VDC - Replace the control unit.
• 0VDC – Replace the bus cable.
