Found a YPVS tacho from a 350 but that is all I have , so what else do I need to make it work ?

The rest of the Yvps ??
Beyond that... for transplanting to another machine.. a feed from the CDI.
Might even tap off the Orange Coil feed signal ??

Yes i meant to say to fit into some LC clock cases for the hybrid
Now if it had a different face decal (needle) and a tiny digital temp gauge cut into the tacho face !
I remember someone did this but on an LC Tacho
What connects the YPVS tacho up to juice then :-) |

You need a 12v power soupy and the trigger off the ypvs cod that feeds the pv controller
Coil signal won't work as not a pulse trigger

On the back I see just 2 brass threaded connectors, it's not as simple as that though is it !
Will it need grounded too ?

There looks a big enough gap to get a small digital thermometer in and as it will be sitting behind the glass , you won't be able to push any buttons , so needs one that is as simple as ?
I don't even know if the actual tacho works or not  |

LC clock not working ? Or no tacho cable fitting in the cases?
Beyond that, the Yama 'lectric tachs can be every bit as inaccurate as the cable driven versions.
Only worthwhile bit of that thing is the face and the needle. Transplant the innards of a younger (and much smaller mechanism) tach into it.
In which case.. using the face, needle and temp gauge from an LC clock could be cleaner and possibly
even easier

I do believe you are onto something there Bare !
Need to check the face of the YPVS tacho versus the LC tacho face to see if the markings are similar
Temp gauge already built in :-)
May have to source a non working tacho then for the bits

Doesn't look like that idea is going to work :-(
The 1 to 12 numbers are in a different place on the LC tacho and not all the YPVS tachos are the same either
Think mine is an 85 onwards so could only use that reproduction decal to keep the numbers where they are supposed to go

Cheers for the pic Andy
What does it look like under the covers ?
I just have the circuit board with 2 brass threaded holes and one visible black wire and a red wire

Many thanks for the pics but looks like bad news for mine :-(
In the last pic, the top right brass tang is missing and looks like 2 little dodgy blue wires soldered on BOO HOO
Anyone got a working one for sale :-)
