Possible both are faulty then. Try a better known brand and replace the electronics.

What results did you get ?

Good, the mosfet's are consistent.

Yes it's one of the 9 mosfet ones and dual voltage, add a nice KT lcd and voltage will be recognised automatically.

Ask on ES they are pretty hot with the TSDZ knowledge.

I would replace the Green mosfet as it is a weak link and may thermally cut out.

I don't know why you keep insisting of writing up as a voltage test is a resistance test and should be denoted as such by writing ohms or inserting .

A strong heat resistant double sided tape to ensure the Hall pcb stays attached to the insulation barrier beneath it.

You was nearly there with the original repair so will have to try again. For mosfets try and drain them of the voltage for a better reading, disconnect the controller from the battery and then to touch the controller Black v- & Red v+ together to drain the the voltage. This will give a brief...

The Green/Yellow phase wires look fried to me and looks like the Green has overheated and the core visible. The Halls, one has to solder the correct leg and check they are orientated right as they only fit one one with bevelled edge. Use the white sheath to insulate the legs when soldered.

The mosfets don't give a voltage reading, the reading is ohms resistance. The one at 8 ohms is quite low and is weaker then the other two it should be nearer to 9.7 ohms. The Halls will have an identifier number on them, I can't read them as the pic is of poor resolution when blown up. Use a...

Show a pic of the bike !! Is it torque sensing PAS ?

It will be attached to the Bottom bracket if a cadence type is used and can be either side, it is obvious if fitted to the non drive side. The brand may actually be a Storck and German.

Test the motor Halls for a fault with voltage via the 5v rail, one will need battery power and all connected up. HallSensorTesting.cdr (ebikes.ca) If the Hall test is ok, try checking the controller mosfet's, no power needed and looks for resistance failure in the mosfet. Simply test the...

I see six three thicker phase and there speed sensor wire Red, Blk & Wh. You need a sensor less controller with the speed sensor connector like this one, it has a PAS connector, throttle connector if needed and the LCD connector. Select any Kt lcd display to use. Sensorless Brushless Motor...

Display has to be compatible with the controller brand.

One can only know where the fault lies by testing, guessing or hoping get's you know where when you don't get the answer you were looking for. Mosfet's are in the controller, one must test them with no power as it is a resistance test using the 20 or 200 ohms range. Test Black controller wire...

What model battery is it ? Some carrera ike use a phylion case battery and they can be had for about £200 from Yose power.

You have show that the motor wheel frees up and turns by disconnecting the controller so rules out the motor phases and cable as the issue. I have already described the process in you other many threads or in the PM's. Follow the two pdf links for testing. BlownMosfets.cdr (ebikes.ca)...

I will start the ball rolling as I mentioned in the PM. Test and test a again, it's the only way. It worked to a degree before the wire became twisted and broken, so the shorting that will have occurred has either blown the Halls again or the controller mosfets. Voltage test the Halls as before...
