The tests below will allow you to check that you are getting correct power supply and charging to various points of your system. This will allow you to find any potential problems that cause a loss of power.

1. Incorrect Battery/Power Connection
2. Damaged Fuse
3. Low Battery Voltage
4. Faulty Power Adapter
5. Faulty Charging Circuit
6. Damaged Control Board

*If you are uncomfortable or unsure about performing any of these tests please contact Richmond Wheel & Castor for further support.

1. Check the battery and wiring connections for loose or disconnected wiring. Please see images below.

2. Open the fuse box and check the fuse for damage. Opened fuse box & damaged fuse shown below.
- Fuse type: T5AL250V Glass Fuse

3. Using a multi-meter (if available), check the voltage of the batteries together and individually
- Battery voltage should be above 11.5 volts DC individually, and 23 volts DC combined.
- If necessary, re-charge each battery individually using a 12-volt Deep Cycle Battery Charger
- If batteries are below 18 volts DC combined the power adapter will no longer charge the batteries

4. Using a multi-meter (if available), check that the power adapter is supplying sufficient current
- Voltage should show approx. 36 volts DC at testing point

5. Using a multi-meter (if available), check that the charging circuit is operating correctly
- If batteries are not fully charged, the reading should be between 1 and 10 volts
- A zero-voltage reading indicates either full batteries (see step 3) or a faulty charging circuit

6. Check the PC Control Board for any obvious signs of physical damage.
