The Havoc ESC is equipped with internal protection. The following is a list of error codes depicted through LEDs––most flash when throttle is applied.
• All status LEDs scroll from left to right––Check blue sensor harness wire for disconnection or motor does not have temperature protection. For proper operation, replace blue sensor harness wire or motor with temperature protection. Check Novak Web site for motor compatibility list.
• Red & Green status LEDs on solid––Check input signal harness connections at ESC and receiver. Check input signal harness wiring sequence––Refer to Step 1.
• Red status LED on solid & Green LED blinking––Check motor sensor harness connection. Possible internal motor damage.
• Blue & Green status LEDs both blinking—Possible ESC shut-down due to locked rotor detection––Return throttle to neutral position to regain motor control––Check vehicle’s drive train for free operation.
• Green & Red status LEDs on toggle––Li-Po Cut-Off triggered—Replace or charge battery. Battery voltage may be too low.
• Blue & Red status LEDs blinking—Possible ESC thermal shut-down—Check gear ratio & free operation of drive train for possible overloading/ESC is being severely over-loaded––allow system to cool & return throttle to neutral position to regain motor control. LEDs will continue to blink until system is cooled down.
• Blue & Amber status LEDs blinking—Possible motor thermal shut-down––Check gear ratio & free operation of drive train for possible overloading/motor is being over-loaded––allow system to cool & return throttle to neutral position to regain motor control. LEDs will continue to blink until system is cooled down.
• Blue & Green (Locked Rotor Detection), Blue & Red (ESC Thermal Shut-Down), or Blue & Amber (Motor Thermal Shut-Down) status LEDs blinking—ESC may have shut-down & ESC’s neutral point is too far off to sense that transmitter throttle has been returned to neutral—Refer to Step 4.
