My tachometer doesn't work when the outside temp is below about 60° F. When the car warms up it eventually kicks in, but when it's cold outside it doesn't budge at all.

Any ideas?

 

Gee, I had forgotten that issue with mine since it has not gotten that cold in the south so far this year. It usually starts sticken when the outside temp. gets down in the forties. But thanks for the reminder.

 

Mine does the same, i figure its the grease in there, just reminds me to not get on it til it warms up

 

Yup, same here. It pisses me off sometimes since my choke doesnt work and I am not sure how high I am holding the rpms sometimes. Oh well.

 

well since no one is answering, and we are all sharing our woes, then mine does the same, but didnt used to do it until i swapped the cluster for an 83 so it goes to 130mph now (it hasnt gone to 130mph yet)... havent tried to max it out

 

Mine does the same thing, but only when it's below freezing. The solution I found was to warm it up!

 

same here. Did it back in the summer here in TN so I know cold weather is not a factor for me. It seems to only not work when it is raining outside or just alot of moisture around. It kicks in by the time the engine hit normal operating temp.

 

Mine does the same thing.. I bought a small aftermarket Tach to put in front of it, and that solved the problem.

 

Old grease is the problem.

 

Very common complaint looking at this thread - was reminded of this just the other day. Tach sticks until about 15 min into the drive. It's amazing what you forget about 'cold' weather driving over a long summer!
