## ⚙️ Key Features

-   Relay from the Other Electrical Equipment group
-   0.061 kg
-   Supersedes 870670
-   Covers 48 applications across AQ, AQD, TMD, MD, BB and TAMD series engines

## 🔌 Function

Switches a heavy load with a light control current, so the heavy current never passes through the switch or control circuit that commands it.

## ⚠️ Common Signs of Failure

-   Nothing happens when the circuit is switched, and no click from the relay
-   Load working only sometimes, or coming on with a delay
-   Chattering or buzzing under load
-   Melted or discoloured casing, or a hot smell
-   Burnt or welded contacts found when the relay is opened

## 🛠️ Service Notes

-   Substitute a known-good identical relay to confirm the fault before ordering
-   Check the base terminals and the load circuit for heat damage - repeated relay failure points at the circuit, not the relay
