What to do if Mile Marker SEC15 Winches motor does not turn on?
- S
  Stephen DavisJul 28, 2025
  If the Mile Marker Winches motor doesn't turn on, several issues could be the cause. First, ensure the safety switch is ON. Check that the switch assembly is firmly connected to the connector. Inspect the battery cable and tighten any loose nuts on the cable connectors. If the solenoid is malfunctioning, tap it to free the contact while applying 12 volts directly to the coil terminal; you should hear a click. If these steps don't work, the switch assembly or the motor itself might be defective and require replacement. Also, check if water has entered the motor; if so, drain and dry it, then run it in short bursts without any load until it's completely dry.

  If your Mile Marker Winches motor runs slowly or lacks normal power, it could be due to a battery that runs down. Recharge the battery by running the vehicle engine. Another potential cause is insufficient current or voltage, in which case you should clean, tighten, or replace the connector.

What to do if Mile Marker SEC15 motor runs in one direction only?

  Teresa GreenAug 15, 2025
  If your Mile Marker Winches motor only runs in one direction, the issue might be a defective or stuck solenoid. Try tapping the solenoid to free the contacts. If that doesn't work, you may need to repair or replace the solenoid. Another possible cause is a defective switch assembly, which would also need to be replaced.

  If the Mile Marker Winches motor runs but the cable drum does not turn, the clutch might not be engaged. Turn the clutch gear to the IN/ENGAGED position. If that does not work, ask a qualified technician to check and repair.
