Ignore the lamp, is the relay actually working as it should?

Use a test lamp, I have a bulb holder with croc clips on and pop it up on the valance and switch the ignition on, the lamp should glow for 30ish seconds and go out, I often say listen for the click and the dimming of the instrument lamps ought brighten when it switches but it's not always the case and the test lamp is the best indicator

Clip it on the end of the glow plug and on an earth, pop it on the valance so you can see it from the cab and flick the ignition on and see what happens.
