Glow plug

Can anyone tell me how long the glow plug light is normally on for when starting from cold,mine comes on for just a split second is that normal cheers dave.

It depends on how cold it is, the light is based on the resistance of the glow plug so when it's colder the light will stay on for longer than when it's warm out. Once the light goes off, the plug continues to get a lower voltage feed until the relay clicks off.

Thanks for that i will see what happens when it gets really cold it won't be long.

My wee light just flashes on. The glow plugs will be on their maximum setting for about 20 seconds. If you turn the radio off and listen, you'll hear the relay click off (it's on the driver's side somewhere).
