When your boat windlass is not working, it can turn a simple anchoring task into a major hassle. This guide is designed for yacht owners who want practical, straightforward steps to diagnose common windlass problems without calling in a specialist right away. It will help you understand whether you can fix the issue yourself, need urgent professional help, or can postpone repairs until you reach port.

Safety First: Before You Start

Always disconnect power to the windlass before inspecting or attempting any repairs to avoid accidental activation. Keep hair, clothing, and hands clear of the chain wheel or gypsy during testing or operation. Never use the windlass to pull the boat forward—this can overload the system and cause damage or injury.

Step 1: Check the Power Supply

A non-responsive windlass usually stems from an electrical issue. Start by checking the circuit breaker or fuse dedicated to the windlass circuit. Reset any tripped breakers before proceeding. Use a voltmeter to check for voltage on both sides of the breaker and at the windlass motor terminals.

• If you find no voltage at the motor, inspect battery cables for corrosion, damage, or disconnection.
• If voltage is present but drops significantly under load (below 9V for 12V systems), battery or cable issues may restrict power flow.
• Loose or corroded electrical connections frequently cause power loss; clean and tighten them as needed.

Step 2: Listen for the Solenoid

If your windlass switch clicks but the motor doesn’t run, the solenoid could be at fault. The solenoid acts as a heavy-duty electrical switch, directing current to the motor when activated.

• Check voltage going into and out of the solenoid while operating the control switch.
• No output or a clicking sound without power indicates that the solenoid contacts are corroded or worn out and need replacement.
• Repair underlying low-voltage issues too, or the new solenoid will fail prematurely.

Step 3: Inspect Mechanical Parts

If the motor runs but the chain doesn’t move, the clutch is likely slipping.

• Refer to your windlass manual to locate the clutch adjustment—some models have a hand knob or winch handle.
• Tighten the clutch moderately to ensure the motor’s power transmits to the chainwheel (gypsy).
• If the clutch is properly adjusted but slipping persists, gears inside the windlass may be stripped, requiring professional service.

Step 4: Check for Rode and Locker Issues

Sometimes the problem isn’t mechanical or electrical but a jam or tangle in the anchor rode (chain or rope) inside the locker.

• Inspect the anchor locker visually for chain bunching (“castling”) or snags. Chain should flow freely without piling up underneath the hawse pipe.
• Ensure sufficient “drop” inside the locker to prevent chain accumulation.
• Addressing rode tangles can restore windlass function immediately without professional intervention.

Step 5: Assess Severity and Decide Next Steps

Symptom	Likely Cause	DIY or Pro?	Urgency
No power to windlass	Tripped breaker, battery/cable issues	DIY (breaker reset, clean cables)	Immediate if anchored
Clicking solenoid but no motor	Corroded solenoid contacts	DIY (replace solenoid)	High if anchored
Motor runs but no chain movement	Loose clutch or gear damage	DIY adjust clutch; pro if gear worn	High under way
Chain jams in locker	Rode pile-up or improper chain drop	DIY clear locker	Medium if safe anchor
Windlass runs intermittently	Voltage drop, wiring faults	Pro if complicated	Moderate

If your checks reveal simple issues—like a tripped breaker, loose wires, or dirty contacts—you can usually fix the boat windlass not working problem on your own right away. For clutch adjustment and clearing rode jams, these are manageable for most confident boat owners.

If the problem seems mechanical involving worn gears, motor failure, or persistent electrical faults despite your efforts, don’t hesitate to get professional help. Continuing to operate a faulty windlass risks further costly damage.
