🔌 Function

Carries power, ground, communication or control signals between the specified engine, display, control unit or vessel-side components.

⚠️ Common Signs of Failure

• One branch of the Y dead while the others still work
• Control-unit communication dropping out intermittently, often with vibration
• Corroded or pushed-back terminals in one of the eight-pole housings
• The overmoulding at the Y split cracked, letting moisture into the joint
• Fault codes that clear when a connector is unplugged and reseated

🛠️ Service Notes

• This is the three-way eight-pole Y cable, so check all three legs when diagnosing - a fault on one branch reads at the control unit as if the whole circuit is down
• Check the connectors and their seals at both ends before replacing the cable
