Random one.

Basically, new gauge and sensor. 

From cold, it rises as engine temp does to 250-300degrees then dies.

Then once engine warm, driven it, the gauge on ignition position 2 does what the video shows...

It follows the operation of the glow plugs!? You can just about the click as the glowies turn off as the gauge buzzes back to 0

random. 

Only thing i  can think is the gauge shares its power supply with the others?!
