Got a S Drive given you 8 flashes ? motor brushes are good , bad news controller fault ? not always... the brake function is related to the motor output so a bad brake resistance etc can cause a 8 flasher when it should be 5 flashes, very annoying I admit .
if you have the 8 flash code, a 6 flash code on some controllers , check the disconnected brake resistance( 25 upto 80 ohms) ,, check the actual connection on the controller , is the pin looking a dark colour compared to the other pins ? you got a corroded pin if it is and a possible cause of the fault(s) you're experiencing ..
Now here's a beauty, got a controller no fault codes but wont drive ... everything checks out , brake resistance, motor resistance, battery voltage stable .. see if you can turn the throttle lever a few degrees to the left , keep it there in that position now turn the scooter off , back on, no error codes , see if it works
do the same to the right ... Im seeing a number of controllers as they age produce this problem...
