I've just switched on my, mostly built, chair and got 9 flashing lights. Diagnostics confirmed 'right solenoid brake' fault. Code 1506.
Last week I quickly plugged in the old (obsolete) electrics to test the motors, and the left wheel moved but then it stopped and 9 lights flashed. So I've been hoping that it was the old electrics that were at fault.
I've just swapped the motor cables over to see if it would give a 'left solenoid brake' fault (code 1505) but it still said 'right'.
(The wires that tell the module that it is in free-wheel mode are not connected, like on the working chair.)
So I've now got to take the r.h.s motor off this chair and plug it into the working chair to confirm the faulty motor. Unless you can think of a better plan?
