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.

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
