In my 1983 NA 280zx, I bought it with the digital dash not working properly. The speedometer lights up but doesn't move past 0, and I found out that's because the speedometer connection is not connected behind the dash. The RPMs work just fine.
My main problem is that the Fuel and the Temp gauges do not work. They do not turn on at all. I really don't want to be guessing how hot my engine is. I've taken it the combination meter out of the car. I've read that there is a 1 Amp fuse on this that I could clean and/or replace etc... that might fix the problem.
What do you guys suggest? And can anyone point out where the fuse is in my pictures? Pictures are attached to this post.

Thank you


Also, all the connectors were connected when I originally took it from the dash. I will go back and clean the female end of those, as well.
