what is this.

[wijnendael]

Well i am here again, i am currently rewiring our boat and there is one gauge that i cannot find any info on. The picture shown is with the engine running, on the back there are the supply connections and two more S+ & S- they go to a sensor on the engine looking at a magnet (i think) on one of the pullys. If somebody could assist me with where i may find a manual or tech info for this it would be appreciated so i can put it back into use.

Equus make tachometers, so I would expect it is a digital tachometer and judging by the little D with the arrows, it could indicate shaft speed.

Whatever it is, it isn't displaying properly.

Same shape/design gauge as a Honda hour meter I have on my RIB, all be it its now coupled up to a Yamaha outboard.

Agreed, its not displaying properly though.
