Tachometer sometimes not working

An old problem I’ve had, that I forgot about since the car’s been sitting in the garage, sometimes when starting the car the tacho won’t work. It usually comes to life when I start driving, or restart the car. It doesn’t happen every time either. Any ideas?
I thought I’d check connections behind the cluster, I have new fuses on the way for the fuse box.
 
Same here, occasionally tach does not work at startup. Slight bump of the dash wakes it up or when I give it a rev. Is there a fix for this?
 
I don't know about a fix, but the tach is the same on the 400E420, so I'd swap it out with a spare from a donor .034 cluster and see if that helps.
