Speedo/Tach moisture behind glass lens

[gsmitty]

Anyone have an issue with moisture getting behind speedometer and tach glass? Got caught in rain last year and now I have water spots on the inside of the glass on both.

I pulled the cover off of the back of the Tach and it appears you cannot remove the glass.

Thanks

Let's see, I've owned 3 Triumphs and all three did this from time to time after riding in the rain.

I have generally just let them sit in the sun for a day with the back off, and the moisture went away.

Mine are Okay

I've only been in a couple of light showers and 2 pretty hard down pours. So far, all is dry inside all 4 gauges. For what it's worth, here's a little trick I've used on several double glazed glass for airplanes and railroad car windows.

Find the smallest drill bit you can find and drill several holes at the bottom of the glass. It releases any moisture build up and lets the air help dry out any latent moisture. Seems to also keep down the fogging of the glass.
