Hi Peter,
In this circuit, the two electrolytic capacitors can be removed and the basic function will remain. The one larger cap I mentioned is there to smooth the speed meter deflection. A very unlikely fault could result in it shorting out intermittently inside, which could cause the needle to drop to zero, but this would be independent of the odometer. Very unlikely.
The most likely fault with the electrolytic capacitors in this gauge would be diminished capacity as they dry out, and it is unlikely a driver would ever notice the effect. How different this is from the Yazaki gauge the 7/9 folk are saddled with, where the caps leak and destroy the circuit board.

Being right is highly overrated. Even a stopped clock is right twice a day.
