Default Oops electrical - Earth?

Hi Guys, All of a sudden my cluster gauge lights don't work(speedo & rev are fine)and at the same time the temp spikes out but if I turn the dimmer down it comes back to normal - Earth I guess?

If I were a betting man- I'd put my money on a bad ground at the cluster or Voltmeter (guessing your car is a 75 or later...)



Same problem- and their solution-

Thanks team,I appreciate your input, Right now I've pulled the cluster while I was at it thought I might as well check for a vacuum leak behind it
Will keep you up dated on both
Cheers Dave

Right, found the issue with the electrics, it was the main harness plug had just about popped out-my fault for not checking it last time I had the dash out!!
Also fixed the vacuum leak, which was the vacuum switch- needed a little Vaseline grease
Thanks for your interest Cheers Dave NZ
