Suddenly the Bafang BBS02 motor stops running
I get a error 08H controller report on the screen (motor hall signal wire error)
I open the controller and made a connection to a other motor and it worked
So the controller is it not
Then I connect the controller to the faulty motor
I do not...
I have changed the controller and the motor is working again
but without start-up (push button) it worked
I have changed the power-up push button and the lcd screen
and also this problem is solved
A lot goes wrong with the bafang BBS02
unreliable
I have bought a new bafang bbs02 and I have changed the old motor with the new controller and the motor worked. But without start up. It drives without power up!. I can also start up and the screen is working and it work normal. What is wrong?
I made a new connection with new connectors to be sure
I'm now waiting on mine new bafang 48v750w
I saw that one of the plastic isolates from the connector in the controller is bad
and can give short circuit with the metal of the controller
I received it so, this is bad work from bafang
And I do...
negative
green = 10 Kohm
yellow = 10 Kohm
blue = 10 Kohm
Positive
changing green 1 time 0,5= Mohm 2= 68,5 Kohm 3= 16 Kohm
yelow 1 time 4.6 Kohm 2= 70 Kohm
blue 1 time 4.6 Kohm 2 = 0,5 Mohm
The result are always changing with a new try between positive and the wires.
No it was water in the controller, since then I have all different problems
I think to buy a new complete bbs02 or only a new controller
than I can always made a better diagnose with new components
and the defect product I can sent back to China in warranty I hope
The problem can be the display...
I have never see error code 12 this morning
It start with error code 3 than 4 than 30 and than nothing no more
the resistance of the fat wires green, yellow and blue out of the controller give;
green yellow 42Kohm
yellow blue 22Kohm
green blue 38Kohm
I start mine motor again to go to work this morning, I get always error code 3? Error code 3 do not exist in the manual?
After search after the fault and restart, change nothing I get error 4?
Then I change the throttle I get error 30.
I have to push very long on start button before the display...
when I start up, the motor starts sometimes, when I stop, the motor do not start again. Power off, power on, nothing. Start up, when motor work ok, I long I give gas. When I stop, nothing no more.
