When the weather is cool on my drive to work in the morning the tach does not work, but on the warmer drive home after work it works just fine. Any ideas?

Clean and lightly graphite the moving parts. If it's cable driven, remove the inner cable, clean and graphite that too. Much easier to try the cable first, obviously..

Hah!

My speedometer did the opposite- worked on cold mornings, but not when it was above 20F ambient...

Changed the cable, the odometer and speedometer stopped working completely. Pulled the whole monopod, took out the speedo/odo and shipped to Palo Alto. I know, I know, it hurt spending the $200 plus. But the speedo/odo have worked fine since then- hot/cold, in between...
