Outer Limits 4x4 Board

I'm new to diesel an i know the coil light is to show you that the glow plugs are warming up an you should wait till the light goes out before you start it. But should the light flash on an off quickly while driving... as it came on a few times on the drive home tonight i could barely realized it flashed it went that quickly, its not constantly doing it just every now an again it will flash on then off. Is this normal or is something wrong.

Thx

No, the glow plug light should only come on when you are starting the car. It could be a crook timer, a crook relay, or possibly a dodgy connection somewhere.

thx mate ill have a look at the connections if that fails ill get someone to look at it.
