My Carrera vengeance has a mind of its own... When I turn it on it either puts power on for 8seconds or 8mins or up to the length of my journey.
Mind it is only powering 2 of the 3phases of the motor and has been doing this for some time. I have checked the wires going in to the axle and not found any fault of a broken wire. I concluded that it might be one of the hall effect sensors but I don't know what they look like.. Transistors? There's 3 of them spaced 120 degrees around the board but I don't want to unsolder the board off if I don't have to or at least till I know what I'm dealing with for definite.Especially cos its a sealed 9 pin plug with no access to place any multimeter probes to prod in and check when it is running!!
This said is it my controller that's at fault?
It never comes on the same way as to when I last switched it off its a kind of hit'n'hope affair with it.
If one mosfet is broken would that cause my motor to only power up 2 phases oh and cause a mechanically horrible noise of which I've read about elsewhere ?
I've had it apart numerous times other than actually desoldering the wires off it but all to no avail.
After the chain coming off and cutting through the sensor wires which I fixed I've since replaced the torque sensor and understand exactly how that works, way too fussy for mountain bikes in my opinion with mud and water etc.
Can anyone on here help me either fix it or what I need to get bearing in mind I'm very low/limited on funds and can't afford to buy things just to check If this will work or If that will. Thankyou all in advance, for any and all opinions that just might get me back on the road properly and even illegally if it can get that little bit of extra umph...!?!?

if it were my bike I'd slap a 52v battery on it and cheap 1500w kit not legal but fun 8)
