Not too sure of this, but...would a four cylinder rev-counter work on a two cylinder engine and be accurate? Unless the car in question has a GS engine, then my question is redundant

Has anybody used a Citroen GS Tachometer (Round Analogue) on an A Series. Can you share the wiring information.? |

Neil had one converted at cost IIRC and used it in his Dyane ok. I bought one form eBay for a Harley for the Ami (602cc) and that works fine. All depends what you want it for or to do. |

Yes, its a resister swap, but i cant remember if its value is 200% of original or 50% of original. Ive also heard various rumours that it doesnt actually work acurately when its done either... Andy M

The supplier who I got it from is still in business, but I don't think they supply converted G tachos any more - they used to be a catalogue item. Perhaps, Andy, you could ask your employer tomorrow if he remembers what he did with them...? <g> |

I guess I can go really anal here and put my penny worth in. If you have a Sad-Naff(sorry,I do), they are accurate(something to do with trigonometry  ...I believe). The gear-ratio of 4th gives something like 13mph per 1000rpm. At 65mph, you should be reading 5000rpm or there abouts. So with a sad-naff reading of 65mph, see if the rev-counter tallies, if it does, then the other ratios(gears) should match, giving accurate readings through the range......hopefully
