Throttle is Not Working / General Troubleshoot:
Follow these troubleshooting steps:
- Are all the lights on the throttle on? Do they stay on when you try to use the throttle? if you answered yes to both questions then proceed to step 2. if you answered no to either question then check the voltage on your battery using a multimeter and determine (or ask) if it is an appropriate voltage for your motor.
- Turn off the battery, unplug the brake levers and everything else other than the throttle, then turn the battery back on. If the throttle works then turn off the battery and then plug each disconnected item in one at a time, power up again and try the throttle to determine which one is causing the issue. If the throttle still doesn’t work, proceed to step 3.
- When you turn on the battery do you hear any repeating beeps from the horn? If so, count how many consecutive beeps you hear; the number of beeps indicates the error code. Each error code’s meaning can be found at the bottom of this article.
If you have determined the issue and require a warranty replacement or are still unsure what the issue is, please open a support ticket.
Motor is Stuttering / Jerking / Making Noise:
If the motor is cutting out, stuttering, jerking, or making noise but not moving, there could be a few possible causes:
- The battery can’t supply enough continuous current so the motor could be cutting out. Usually, this happens when the battery is purchased from a cheap store instead of Golden Motor. If the motor works perfectly fine at low throttle but cuts out at higher throttle, this is probably the issue. The simplest solution would be to program the controller to pull less current from the battery. This can be done by decreasing the “Battery Current (A)” incrementally until the issue is solved. The more expensive solution that would allow your motor to run at full power without issues would be to purchase a better quality battery with a higher continuous current rating.
- Phase or hall wires are not connected properly. Make sure your wiring is correct.
- Faulty/damaged hall sensors in the wheel. This can be solved by running the motor in sensorless mode, check the section below.
- A faulty connection or component in the controller (more likely).
- A faulty connection or component in the motor (less likely).
Also, check the troubleshooting steps above, and count the number of blinks on the controller. This could give you more information on what the issue might be.
If you have determined that the issue is with the controller or the motor, contact our support team with your test results.
If you are unable to determine the issue, record a video of the motor behaviour and send it to support@goldenmotor.ca to open a support ticket.
Sensorless Mode:
If the hall sensors are damaged or faulty, you can run the motor in sensorless mode. This video details the process.
Motor is Working but Making Noise:
There are different noises that could be coming from the motor/wheel. Take a look at some of the common noises below, as well as some of the causes. If you still aren’t sure what the cause of your motor noise is, send a video of the noise to support@goldenmotor.ca to open a support ticket.
Clanking or rattling in the rim:
Most likely, one of the spoke nuts got loose and fell into the rim. You will have to remove the tire, rotate, and shake the rim to get it to fall out. Make sure you replace the missing spoke; take a look at this article for help with that.
Knocking noise once per revolution:
If your motor is making a knocking noise once per revolution, something may be catching internally or externally. Rotate the wheel slowly by hand to determine where exactly the noise is coming from. Check the disk brake screws, spokes, freewheel, etc. to find the culprit. If there is nothing catching externally, there may be some contact internally that needs to be rectified. Contact the support team if this is the case.
Constant grinding noise increasing with RPM:
This noise may be the disk brake screws grinding against the motor casing. If this is the case, you will need spacers on the screws to increase clearance from the motor casing. Another cause may be noisy bearings. There are two bearings inside the motor that can be replaced. Open a support ticket to ask for details about purchase and installation.
Error Codes:
If there is an issue with the external hub kit, the horn might beep to indicate an error code. If the horn is going off repeatedly, the number of consecutive beeps is the error code number.
1 repeating beep indicates Over voltage protection
2 repeating beeps indicate Under voltage protection
3 repeating beeps indicate Over current (Motor phase is short-circuited or phase to ground is short-circuited)
4 repeating beeps indicate Stall Protection (motor stalled for too long)
5 repeating beeps indicate Hall sensor input is abnormal (or connector disconnected)
6 repeating beeps indicate MOSFET protection (MOSFET self-checking is abnormal)
7 repeating beeps indicate Phase wire disconnected (or faulty windings)
10 repeating beeps indicate Self-checking error protection (System internal power-on self-checking is abnormal)
11 repeating beeps indicate Controller overheating
12 repeating beeps indicate Abnormal throttle signal
13 repeating beeps indicate Motor over-heat protection (Motor temperature is higher than safe value)
14 repeating beeps indicate Throttle or control harness are disconnected or faulty
