Recently did a few things with mine.
Temp gauge was showing nothing, and the heater stopped getting heat and going up a hill hard, I could get a LITTLE bit of rising on the temp gauge. So figured thermostat.
I did not even think of pictures of that stage of the game until I was all done and running it for the first warm up.
Got done warm it up, still no temp reading, but now I get heat.
Unplug the sending unit from the head and ground it, Yeap get needle deflection so the gauge and the wire are working. So I swap the sending unit from a parts car (thinking I Have it solved and dinner on the table I top off the water and head in) (Yea I did skip testing it but I was sure I had it figured out). Next day drive for an hour to work and then an hour back and never get ANY needle movement (not real happy about driving it with no temp gauge What the heck. pull over and re-ground the wire and again can see the needle move (nice part about the mid-engine I can look over the engine cover and see the dashboard.)
Kinda at a loss so I again swap the sending unit this time with the wife's X so I KNOW this one works. Get her car put back together and have her start it as I go try her sending unit in my car.
Right away she get needle movement....?? ??? How can this be... And of couse when I install in my car I still get nothing.... At this point.. I re-test by grounding the wire and now I get NO movement. (what the heck). and pull the instriment cluster. And swap with another instrument cluster and I get a needle movement (full hot as the wire is still grounded). Ok I found the problem. And I swap the temp gauge with from the other cluster and plug it in again. still no movement.
So I plug the wires into the cluster and come back into the house and find the pinout for the cluster. I think I can thank Bob Brown for the GREAT picture/lables!! I ground the wire at this point and still get no movement. Out comes the multimeter and I test between the lug on the temp gauge and the plug and I read open, probe the trace and I have connection. (what the heck)
Found it did a little cleanup and threw the little washers away and I have a temp gauge again!!
Now for the sad news.
When I was driving the car I wiggle, tapped the dash area to see if I could get a needle movement Only thing I got was the speedo falling to zero. Yeap twisted the long cable about 4 inches in.
I think I can blame that on the condition of my short cable.
Would you believe I got to the speedo cable issue just before 6
m Midwest Bayless time and was able to get some parts ordered in time.
And thanks to Sdlsaginaw I have a short cable already. Kinda wish now I had installed in sooner.
Wife started playing with her's, going to swap engine covers. The current one she has is a great lightweight racing cover, But as for a daily driver being able to pull the release and open the cover to check the oil/water.
Got her new pull cables coming and a good used frunk latch and cable for mine on the way. Getting kinda tired of my frunk alway's being lifted up just a little.
And being Oregon about now it starts raining I am buttoning up and she just puts the old cover and we go into the house.
But we both got a little done and had the dirty hands to prove it.
