Omega Electrical and Audio Help / Re: Engine temp not displaying on Dash.

Wish I'd seen this thread earlier (no pun intended) - I might have been able to contribute something useful for once!
I'd struggled to find dowty washers when doing head work - but I thought I'd done a pretty good job of 'refurbishing' the old ones...
And I had - absolutely watertight - but also superbly electrically insulating! I'd wrapped a spiral of ptfe tape around them, a thin film of RTV then a thin fibre washer under the bolt so as not to chew up the tape.
Ooops - no temp display. Help from OOF was forthcoming - so I put a short wire from under the sensor to a nearby bolt to reinstate the ground connection.
Done.
