My BBS02 (750W, 48V) stopped working.
The display is dead, the engine is not running.
No reaction to the connection of the programming cable to activate the drive with the lever, or by turning the pedals.
When I connected a second functional battery, nothing changed.
I removed the controller, measured:
- between the minus and the phases is 6.74 6.97 and 7.65 k ohms.
- between the plus and the phases there are about 290 570 and 220 kilohms.
In addition, on one of the pins in the display connector there is no full 52V battery voltage, only about 22V is there.
Please help me fix the drive.
