Hi folks,

I really need to ask a dumb question; My pwm-controller (sevcon MOS90) diagonstic led flashes 5 times when selecting drive. According to the manual that could mean an contactor problem or "open circuit motor". I connected + and - from the batteries to the motor and it runs bothways. I presume that there's no open circuit in the motor but I'm not entirely sure...

TIA
