## ⚙️ Key Features

-   0.109 kg
-   67 applications across TAD, TD, TWD, TID and TAMD engines
-   Supersedes 863382 and 863481

## 🔌 Function

Holds a starting-circuit function energised for a set period and then releases it automatically.

## ⚠️ Common Signs of Failure

-   Function it controls staying energised instead of timing out
-   Timed period obviously too short or not happening at all
-   Hard starting when cold because the timed function does not run
-   Relay chattering or buzzing rather than switching cleanly
-   Terminals corroded or the base loose

## 🛠️ Service Notes

-   Both 863382 and 863481 are covered by this number, so an older reference is not a different relay
-   Confirm supply and earth at the relay base before replacing it
