Winch silent / no response

• Savwinch: ensure correct wiring of EFF module; battery positive to correct terminal else you void warranty.

• Muir: standard wiring to solenoid—check circuit breaker and helm switch.

​

• Motor clicks but doesn't spin

  • Muir & Savwinch: test solenoid and voltage drop; check EFF module wiring if fitted.

​

• Drum doesn’t move although motor runs

  • Muir DFF: verify dog clutch position; sometimes stuck in neutral.

​

• Works only one way (deploy vs retrieve)

  • Savwinch EFF: if drop is free fall but raise fails, check neutral wiring (blue/brown) wiring per EFF wiring diagram.

​

• Continuous operation doesn't stop

  • All brands: stuck switch or faulty relay; isolated solenoid location
