It's on a Mk III Capri. Was fine until I started up this morning, and ... nothing. I guess it's probably an electrical fault, but that's not my game.
Can anyone give me a basic 123 on how to isolate the fault? The rest of the dash is OK....
Thanks a lot everyone

take the wire off from the transmiter engine end, run a positvie feed wire direct into the temp.wire. the meter should reaf HOT in seconds. if it does change the transmiter, if it doesn't look for broken cable etc. the meter itself seldom gives up.

Hi, are you sure you need a positive to do the check. Normally just touching the terminal to ground will do the trick. You may damage the gauge by putting a pos feed on the cable.

Thanks - I'll give it a try. I guess the safer option would be to ground it first, then try the positive....
Let you know how it goes

definately ground it. The temp sender unit is basically a thermistor to ground anyway, so grounding the wire will mean no real resistance and the gauge will go full scale.

Sorted at last - new sender unit fitted (£5 from eBay) and all is well....
