Rev counter check when out of car?
 

Hi all, after a long search I found and bought a 2.4S rev counter on eBay. Now, unfortunately it fell down the stairs and I have no means of checking whether it still works because my car is in parts due to restoration.

Is there a way to check whether a rev counter works without attaching to the engine??

Thanks

Dennis

Dennis,

You can test the tach on a bench by building my 'junk box calibrator' ... and using it as a pulse source for checking the tach at 1200 rpm and 2400 rpm.

Excellent! I´ll take this diagram to my local electronics shop and see what they can do.

Many thanks

Early_S_Man, FMMI, but there seem to be quite some connectors on the tach. AFAIK, two are for the turning signal, but where do the others hook up to this diagram:
- ´Output´ goes to signal in on the tach I guess, can you tell which one that is?
- any other link between tacho and this diagram I need to make?

I guess what I´m saying is that it would help me if the tacho is in this diagram as well.

Many thanks again!

Dennis
