I drew these gauge sun shields to make my various gauges the same “OD” and and “depth” so they would blend in together better. My son printed them out for Christmas for me on his Bambu Lab 3D printer.

Removed the oil pressure and water temp gauges from the wiring harness. Of course the knurled thumb nuts were rusted tight and would nut come loose even after soaking with penetrating oil. I resorted to heat using my jewelers torch to just heat the nuts then reapplying penetrating oil and then repeat a couple of times. This is usually effective and worked this time

How can I bench check the temp gauge?

Still trying to decide if I want to take the glass off the gauges for further detailing ….

  Bench testing the temp gauge and sender is in the electrical portion of the manual.

  Btw , thanks for the tip in the shims.

There is a good write up on electrical gauges here (http://lotus-europa.com/manuals/misc/electrical/gauges.html) and here (http://lotus-europa.com/manuals/misc/electrical/meterinfo.html) which is from a link on the first page.

On the subject of gauges, I have a tach question. It seems someone posted the tach needs modded to work with the 123ignition?

I found this online as a different solution:

Can someone with an electrical background give their input?

I did this.

I have heard there is a commercial equivalent but do not know anything about it.

I decided to take the glass off the gauges to clean them and to paint the rusty trim pieces in the tach and speedo.

I first tested the temp and fuel level gauges by just using my 6 volt trickle charger and they both moved so they should be good. I already know the tach and oil pressure gauge work from first run. I will check the speedo with my drill.

The small gauges were much more challenging to get apart than the tach and speedo! I removed the gauge to dash gasket with an exacto blade. I then carefully worried the bezel loose with a flat blade screwdriver, I also applied WD40 to bezel gaps on the small gauges with a model paint brush. I bought a strap wrench but it was useless and used a work glove with a grippy material on it to get the bezels loose. On the small gauges the original bezel to glass sealant turned into some kind of mystery gritty material 

Now to clean, touch up, paint and reassemble…..

Just verified with a drill that speedo, odometer and trip meter work

Getting lost in the details again …. everything touched up and ready for reassembly after everything has dried completely. Minor wrinkle finish applied to inner speedo and tach bezels by spraying light coats of wrinkle paint (to cover minor rust pitting).

Nice!

  Looking great. 
 Getting the oil gauge and the sender working in sync was the problem for me. I see you got that covered.

Together …. made new seals/gaskets out of window screen spline material super glued into an o -ring (saw this on a Triumph forum) instead of using sealant, their only purpose is to keep the glass from rattling really, as the gauges are open in other areas …..

VERY nice work, Sir!

Thanks CW!

👍👍,
Nice, thanks for the spline tip.
