## 🔌 Function

Carries power and signals through the installation as one pre-terminated loom, with every branch already cut to length and every connector already fitted, so each sensor, control unit, instrument and switch lands on the circuit it belongs to. In a marine installation the loom and its connectors take the brunt of vibration, salt air and heat, which is why a tired harness so often shows up as a fault somewhere else in the system.

## ⚠️ Common Signs of Failure

-   Circuits that come and go, or change, when the loom is moved or the boat works in a seaway
-   Green or white deposits on the connector pins, or a connector that no longer clicks home and stays home
-   Insulation chafed through, cracked or melted where the loom passes a bracket, a clip or a hot surface
-   A fuse that keeps going, or a circuit that only works with the loom held in one particular position
-   Fault codes reporting open or short circuits on several unrelated components at once

## 🛠️ Service Notes

-   Volvo Penta's EVC installation manual is explicit that the EVC cable harnesses must never be cut or modified, and that a Volvo Penta relay should be used where an accessory needs a power supply of its own.
-   The same manual warns against putting grease of any kind into EVC connectors, and against bus branches longer than 0.5 m (1.6 ft), which it says can generate communication disturbances. It also requires a Y-connector to go straight onto a node rather than through an extension cable.
-   Before replacing a loom, work the connectors at both ends and check the runs where it crosses a bracket or a clip. Corrosion at a pin and a chafe point behind a clip give the same intermittent faults as a failed harness.
