Poor earth from engine to dash harness. Not the sender side of the temp circuit.
Clean and reattach earths.

The fuel guage not connected due to lpg conversion dd

Will study dash earths again... I thought I got all of them. Wonder where this one is

It's all got to do with your earths and + cos they are all playing up! Run around and clean all earths and + and cheak voltage with meter and make sure they are all ok! That's where I'd start!

Thought I cleaned all the earths and the pod I check connections, as for with a voltage meter, ???????? I will find voltage but what it means lol.

Do you have a earth strap from engine block to body shell? It is essential.

Yep replaced that, the cable from block to chasis under battery tray at front. Light sand on both surfaces to ensure good connection too

The instrument panel is earthed/grounded by bolting it to the metal dash frame. Which means if you have it loose for testing, it won't work correctly!

Mmmm it is bolted in but is a bit loose since no radio installed. Looks like its dash out tonight. Thanks all so far

On back of dash what does this tab connect too? On the curcuit board it sits at 12 o'clock and has a line green wire on connecting harnes plug leading into it. Between a yellow and green wire. Sorry pic upside down lol




I'm lOoking at my greggorys manual wiring diagram and bless their heterosexual hearts, they didn't break it down into pastels
