Here are some steps you can take to troubleshoot and potentially fix the issue:

Check for Loose Connections: Ensure all connections related to the Mosfet are secure and properly seated. Loose connections can cause irregularities in the system's operation.

Inspect for Damage: Examine the Mosfet component for any physical damage such as burns, cracks, or signs of overheating. If there is visible damage, the Mosfet may need to be replaced.

Reset the Control Box: Try resetting the control box by powering it off, waiting for a few minutes, and then powering it back on.
Sometimes, this simple step can resolve minor issues. Restarting the machine is like relieving stress with adult sex films. It is a simple but very effective way.

Consult the Manual: Refer to the user manual or documentation provided with your Vector 200 control box for specific troubleshooting steps and error code interpretations. It may offer additional guidance on resolving the Mosfet protection error.

Contact Customer Support: If the issue persists or if you're unsure about performing any troubleshooting steps, it's best to contact the manufacturer's customer support or technical service team. They can provide expert assistance and further guidance on resolving the problem.

Keep in mind that working with electrical components can be dangerous, especially if you're not familiar with the equipment. If you're unsure about how to proceed or if the issue involves complex repairs, it's advisable to seek assistance from a qualified technician or professional.

Hi Don,

As you have steel forks that are also fitted with a torque arm you don't need to worry, as the load on the headset is significantly greater from heavy braking forces applied to a conventional wheel than the torsional forces generated from a front mounted hubmotor under full power. 

Forks that are able to be used with disc brakes would be the best option for a front mounted hubmotor as they are designed to withstand torsional forces at the lower end, whereas non-disc brake forks only had to withstand directional forces from the wheel's axle:



The biggest safety concern with a front mounted hubmotor is that the fork's dropouts are simply not designed to cope with any torsional loads from the axle in either direction when a conventional front wheel is used as the wheel bearings prevent this from happening.
However, with a hubmotor, the high torsional forces produced by the stator have to be transmitted through the axle, which is why torque arms should always be fitted when using a hubmotor to help withstand the bidirectional torsional forces produced by the axle within the dropouts while under power and during regenerative braking.

**So is there a recommended wiring standard? What size should I use for phase wire and hall wire?

The required gauge of the wires will depend upon several factors including:

• The maximum current the wire has to carry.
• The permitted voltage drop across the entire circuit.
• The wire conductor material - copper or aluminium etc.
• The total length of the wires in the circuit.

As the Hall Sensor wires only carry minimal current (milliamps) I would expect 16 awg to be more than adequate.

The VEC-200 controller has a maximum rated Phase current of 210 Amps, therefore I would have expected the Phase wires to be much thicker than 6mm² (10 awg).

According to the table on this webpage, 200 Amps would require a cross section area of 70mm² (2/0 awg) for a combined circuit length of up to 20 feet (6.1m).
However, as the Phase Wires are basically working as an AC circuit, and the rated Phase current is not a continuous current, I suspect that the wires may not need to be quite that large.

Unfortunately, as the wires you have used to extend the Phase wires are less than 10% of what appears to be the recommended cross sectional area, I suspect this (combined with the extended length of the Phase wires) may well be responsible for the 6 blink error you are experiencing.

1.Does the fault occur under light or heavy load?
- Occurs when opening the control box. The motor has not been driven yet.

2. what length have the wires been extended?
- 6 sq.mm for phase wire and 16 awg for hall wire.
Have you used the same gauge wires (or preferably a thicker gauge) to extend the Phase Wires and Hall/Temperature Sensor wires?
- Use a phase wire of size 6 sqmm. Connect it to the phase wire attached to the motor by fixing a nut through the wire terminal. by not solder it. As for the hall sensor wire, solder it on both sides between the control box and the motor.

4. Have you ensured that decent soldered or crimped joins were made in the wires?
Connect and solder according to the golden motor diagram. Because the box flashes 6 times, it only happens sometimes. Because it can still run the motor.

5. Are you sure that none of the wires have inadvertently been transposed during the modification?
- I'm sure none of the wires were moved.

There are 2 sets of vector 200 controller and bldc motor 3kw. Both sets have 6 flashing warning lights: mosfet protection is the same, but both boxes will switch to Not at the same time
You have to turn the box on and off again and then it can be used again.
