It has been quite cold in the Boston metro this week.
Twice my tachometer has been stuck at 0 for the first 20 minutes/15 miles of driving. It does thaw, and I assume that by the time I reach work it is accurate. I am wondering:
1. Am I doing damage to the mechanism by keeping it stuck at 0 when it is meant to be 3000+rpm different?
2. Has anyone else had this issue?
3. If I take apart the cluster and put some dielectric grease on whatever is back there, do you think that would fight against the freezing?
Honestly, I don't use it much to shift, the Justy has a pretty talkative transmission. I do, however, try to use it to mamimize MPGs sans a vacuum gauge (which I don't have yet).
What do you think?

di-electric grease is non-conductive. there is conductive grease but be careful with that.
i THINK ours is magnetically driven. as in a magnet flies around in a circle and theres a second magnet that gets moved relative to the first magnets speed. your tach might actually be stuck on some debris. take apart the cluster, replace all the nights when you are in there and use canned air to blow it out.
if its magnetically drive, nothing is hurt. if its electrically driven, which wouldnt be common for a car of this era, then maybe.

Have you tried smacking it when it's stuck?

mine does this all the time. don't think it's the gauge. mine is often quite inacurate just before it reaches operating temporature. it always returns to functioning normaly, and it's alot better than just a shift light.

Did you mean speed meter or RPM meter?
