Smith Gauge Condensation

[strictlypersonl]

I don't know how the water gets into the gage...

To get the water out, I'd remove the lighting from the back of the gage and aim a hair drier or similar instrument of hot air (no comments about Peter! ) at the back until the condensation was gone. Then do it for an hour more.

FYI-
I get some condensation in one of my autometers from time to time also.

Just this Saturday morning, backing my S/W gauged ERA 289 out of the garage, brite sun, clear, DRY...only the FUEL gauge has a cloud of vapor on the center of the lense.

The other gauges are clear...they always are...the FUEL guage is always cloudy in the AM, maybe other times but I'm not recording data points here.

Assuming they are all open to the world due to the hole for the light bulb...is there a peculiar lubricant used in a fuel gauge mechanism that gasses off, leaves a residue on the lense and you see condensation?...cause otherwise all the gauges should be as foggy as each other...common thread seems to be FUEL gauge...my buddy Robert's ERA 427 fuel gauge does the same thing...but ONLY the fuel gauge...go figure.

The same thing happens with my SW fuel gauge. All the others are fine.

Misted-up guage glasses are an essential part of the cobra experience, and this effect is now enshrined in the "Bumper British book of automotive ****-ups".

Why else do you think that Smith's would go to the trouble of injecting EXACTLY the correct amount of water into each gauge to allow them to mist up correctly?

Some people are difficult to please.
