Hi there I'm having trouble locating the glow plug relay on an 06 fiesta 1.6 tdci, any ideas people? Ford Focus ST3 65 plate Diesel 5 door. Focus mk2 central
Terminals marked 85 and 86 are for the coil. Terminals marked 30 and 87 are the switched contacts. Sometimes the pin out is moulded into the top cover. It's a high current relay, so not a standard size or capacity. The ECM is under the shuttle panel at the back of the engine bay, just left of the battery cover.

Exactly what i was going to say - as the load increases (due to the resistance of the glow pugs) the voltage will drop, 10.5v going to the glow plugs may be quite normal, under load, the battery may not be 100%, with a newer, or more
