flashing temp/coolant light

[corrado-ek 10]

Hi guys, my coolant/temp light flashing and annoys me like hell..

It's a 1991 G60 Corrado

What have i changed ;

-Coolant reservoir tank with new sensor

-Black temp sensor

-Complete dash cluster

 

i think i changed everything related but still keeps flashing,

however i need to tell one thing ;

When i use a blue temp sensor instead of a black sensor so when i have 2x blue temp sensor the flashing stops...:banghead::screwy:

 

Hopefully you can help me out

Sounds like you either have a bad earth or a wiring fault.
