Fault Finding On Shoprider Scooters

Common Fault Finding And Diagnostics For Breakdowns with the Shoprider Mobility Scooter:

Shoprider Mobility Warranty Breakdowns

Often if there is a fault with the Shoprider Mobility Scooter these few tips will assist you to determine where the fault may be. Generally the mobility scooters are fault free if they are serviced and maintained regularly (12 months).


UNIT LIGHTS UP/HORN WORKS BUT UNIT WILL NOT MOVE
Possible Cause:
  • This often occurs when the scooter is in free wheel mode and is not in drive mode. Re-Engage the free wheel lever which is located down near the rear wheels (normally a yellow or red lever).
  • If you hear a beeping noise, the beeping you hear is a fault beep indicating the scooter main control box has detected a problem. Contact your dealer who can diagnose the beep code.
  • Check batteries with load tester - If either battery drops more than 1 volt under a load, the battery(s) are bad. Replace “both” batteries.
UNIT WILL NOT TURN ON
This is a power problem. A power source problem would be between the batteries and the main controller, or from the key to the main controller.
Possible Cause:
  • Check the circuit breaker/reset button and Check the in line fuses located on the battery cables (one for each battery).
  • Load test batteries. If either battery drops more than 1 volt under load, replace “both” batteries (you should never replace just one battery).
  • Use a fault meter to see if power is going to the key switch.
  • If the batteries have just been changed, check that the black battery cable wires are connected to the minus terminal and that the red wires are connected to the positive terminal. If they are reversed you would have the same symptom of unit showing no power. Also check the terminals are not loose.
UNIT CUTS OUT WHILE DRIVING
Possible Cause:
By far the most difficult problem to diagnose is an intermittent problem. Most times the problem must occur in order to locate it. Sometimes you do have some clues. Test drive the unit to find out if the unit shuts off when hitting a bump or maybe even when turning. If the unit turns off whenever it turns right, the problem is most likely the front to rear cable.

SCOOTER HAS REDUCED POWER, LIMITED SPEED AND RANGE
Possible Cause:
  • One or both batteries are defective-check batteries and replace both batteries if necessary.
  • Insufficient charging time, batteries are not fully charged.
  • Batteries are not receiving charge (low battery voltage).
  • Cable connectors not making proper contact, corrosion or bad connection at battery terminals.
ERRATIC THROTTLE CONTROL, SURGING OR HESITATION
Possible Cause:
  • Faulty throttle potentiometer.
  • Faulty speed potentiometer.
  • Loose connections or battery terminals.
  • Worn or dirty motor carbon brushes, or carbon brush spring.
CIRCUIT BREAKER TRIPS FREQUENTLY
Possible Cause:
  • Overload caused by excessive demand on motors (low tire pressure, sticky brake, seized wheel bearings, etc).
  • Heavy load on steep incline.
  • Loose batteries terminal connections.
  • Moisture on connections.
REDUCED BRAKING POWER, SLIPPING ON INCLINE
Possible Cause:
  • Brake worn out/weak brake.
  • Faulty main control box.
