Product Usage Instructions

Steps to Perform Before Control Installation

Check Motor Windings:
- Set VOM to RESISTANCE mode.
- Measure A1 to A2: Should measure BETWEEN 0.3 and 1.
- Measure F1 to F2: Should measure BETWEEN 1 and 2.
- Measure A1 to F1: Should measure OPEN.
- Measure F1 to motor case: Should measure greater than 5M.
Check Main Solenoid:
- Disconnect all wires from the main solenoid.
- Set VOM to RESISTANCE mode.
- Measure the solenoid coil: Should measure 100 – 250 (depending on solenoid type).
- Connect VOM leads to the main solenoid lugs.
- Attach jumpers from main battery positive and negative to the coil (small terminals).
- Meter should jump from infinity to LESS THAN 0.3.
- Remove jumpers and reconnect solenoid wiring from the harness.

This sheet is provided to aid in the installation of your remanufactured General Electric controller. Upon installation, you may encounter problems that may, or may not, be due to a faulty controller. The following steps must be taken to help diagnose a possible cart fault or faulty controller. An analog or digital volt ohm meter (VOM) will be needed to perform these checks.

STEPS TO PERFORM BEFORE CONTROL INSTALLATION

CHECK MOTOR WINDINGS:
- Set your VOM to RESISTANCE (Ω).
- To test the resistance of VOM leads, please touch the meter leads together. Subtract this measurement from each test below to get your true measurement.
- With your motor disconnected, measure A1 to A2. This should measure BETWEEN .3Ω and 1Ω.
- With your motor disconnected, measure F1 to F2. This should measure BETWEEN 1Ω and 2Ω.
- With your motor disconnected, measure A1 to F1. This should measure OPEN.
- With your motor disconnected, measure F1 to motor case. This should measure greater than 5MΩ.
CHECK MAIN SOLENOID:
- Disconnect all wires from the main solenoid.
- Set your VOM to RESISTANCE (Ω).
- Measure the solenoid coil. This should measure 100Ω – 250Ω (depending on the solenoid type).
- Connect VOM leads to the main solenoid lugs.
- Attach jumpers from main battery positive and negative to the coil (small terminals).
- Meter should jump from infinity to LESS THAN .3Ω.
- Remove jumpers and reconnect solenoid wiring from the harness. (If a suppression diode is present, the non-banded side must go to the black/green wire – pin 11 from the controller. Be sure to check diode functionality with VOM prior to install.)
CHECK THE CART WIRE HARNESS:
- Check the connectors on the wire harness for corrosion, loose, broken, burnt or missing pins.
- Repair or replace pins as necessary.

IF ANY OF THE ABOVE ITEMS ARE NOT WITHIN THE SPECIFIED RANGES THE CONTROLLER WILL FAIL. THESE ITEMS MUST BE CORRECTED BEFORE THE CONTROLLER IS INSTALLED OR WARRANTY WILL BE VOID.

It is recommended to replace your solenoid at the time of controller replacement. FSIP now stocks popular replacement White Rodgers solenoids for your convenience

Global GEM Car (353T1) Troubleshooting Sequence

FOR SAFETY, ALWAYS LIFT THE DRIVE WHEELS OFF THE GROUND WHEN TROUBLESHOOTING!
ALL TESTS ARE CONDUCTED WITH A RUN-TOW/MAINTENANCE SWITCH IN THE RUN POSITION AND WITH A GOOD BATTERY PACK VOLTAGE MEASUREMENT. ALSO, THE CONNECTOR MUST BE ATTACHED TO THE CONTROLLER WHEN MAKING THESE CHECKS. YOU WILL NEED TO ‘BACK PROBE’ THE PINS FROM THE WIRE SIDE OF THE CONNECTOR. USE A PAPERCLIP IF NECESSARY.

Attach voltmeter negative (-) lead to main Battery Negative (-) for the following tests. Use the following sequence when checking individual pins (don’t skip steps).

If you find a fault, do not move on to the next step until the fault is corrected:

Measure the voltage at the main battery positive post (let’s call it Pack Voltage)
Pin 1 Must be equal to Pack Voltage
- If not Pack Voltage, check wiring and Fuse for open condition
Pin 6 With Turf Switch Off, must equal 0 volts
- If not 0 volts, check wiring and Turf Switch for a shorted condition
Pin 6 With Turf Switch On, must equal pack voltage
- If not pack voltage, check wiring and Turf Switch for an open condition
Pin 2 With Key Switch Off, must equal 0 volts
- If not 0 volts, check wiring and Key Switch for a shorted condition
Pin 2 With Key Switch On, must equal pack voltage
- If not pack voltage, check wiring, charger interlock and Key Switch for an open condition
Pin 4 With F/R Switch in Reverse, must equal 0 volts
- If not 0 volts, check wiring and F/R Switch for a shorted condition
Pin 4 With F/R Switch in Forward, must equal Pack Voltage
- If not Pack Voltage, check wiring and F/R Switch for an open condition
Pin 5 With F/R Switch in Forward, must equal 0 volts
- If not 0 volts, check wiring and F/R Switch for a shorted condition
Pin 5 With F/R Switch in Reverse, must equal Pack Voltage
- If not Pack Voltage, check wiring and F/R Switch for an open condition
Pin 3 With Key Switch On and Pedal Up, must equal 0 volts
- If not 0 volts, check wiring and Pedal Switch for a shorted condition
Pin 3 With Key Switch On and Pedal Down, must equal Pack Voltage
- If not Pack Voltage, check wiring and Pedal Switch for an open condition
Pin 10 With Direction Switch in Neutral, must equal Pack Voltage
- If not Pack Voltage, check wiring and make sure beeper is present and connected
Pin 10 With Direction Switch in Reverse, must equal approximately 0 volts (and beeper sounds)
- If not approximately 0 volts, check connector and wire terminal for being burnt/corroded. If terminal is clean, controller may be defective
Pin 8 Must equal 0 volts
- If not 0 volts, check connector and wire terminal for being burnt/corroded. If terminal is clean, controller may be defective
Pin 9 Must equal approximately 3.5 volts
- If not approximately 3.5 volts, check connector and wire terminal for being burnt/corroded. If terminal is clean, controller may be defective
Pin 7 With Pedal Up, must be less than approximately .5 volts
- If not less than approximately .5 volts, check wiring and throttle pot for shorted condition
Pin 7 With Pedal Fully Down, must equal approximately 3.5 volts
- If not approximately 3.5 volts, check wiring and throttle pot for open condition  Pin 15 Must equal approximately 4.4 volts
- If not approximately 4.4 volts, remove speed sensor to see if voltage recovers. If it does return replace speed sensor, if it does not return, check wiring.
Pin 16 Must equal approximately 0 volts
- If not approximately 0 volts, check terminal for being burnt/corroded. If terminal is clean, controller may be defective.
Pin 14 While slowly turning the drive wheel, must toggle between 0 volts and approximately 4.5 volts
- If not toggling, check wiring and if necessary replace Speed Sensor and magnet
Pin 13 With Emergency/Park Brake On (Up), must equal 0 volts
- If not 0 volts check brake switch and wiring for an open condition
Pin 13 With Emergency/Park Brake Off (Down), must equal approximately 4.5 volts
- If not approximately 4.5 volts, check brake switch and wiring for a shorted condition.
Pin 11 With Pedal Up, must equal approximately pack voltage
- If not approximately pack voltage, check solenoid coil and wiring for an open condition
Pin 11 With Pedal Down, must equal approximately 0 volts
- If not approximately 0 volts, check terminal for being burnt/corroded. If terminal is clean, controller may be defective.

Helpful Hints

FOR A FULL LIST OF FAULT CODES, CHECK HERE … www.shop.fsip.biz/en/content/technical-documents
DO NOT UNDERESTIMATE THE IMPORTANCE OF MOTOR RESISTANCE CHECKS AND MAIN SOLENOID CHECKS.

MANY CART ISSUES ARE CAUSED BY BURNT/DAMAGED BRUSHES THAT WILL BE FOUND AS PART OF THE ARMATURE RESISTANCE CHECK. ALSO A SHORTED ARMATURE AND FIELD WITHIN THE MOTOR WILL DAMAGE THIS CONTROLLER.

FAQ

What should I do if any of the measured values are outside the specified ranges?
If any of the measurements are not within the specified ranges, it is recommended to correct these issues before installing the controller to avoid warranty void. Consult a professional if needed.

Why is it important to replace the solenoid during controller replacement?
It is recommended to replace the solenoid at the time of controller replacement to ensure proper functioning and avoid potential issues related to old or faulty solenoids.
