I'm not sure if the engine in the Viva, a 2.0 litre pinto which I think is from a late model Sierra has electronic ignition. There is a small black box which has a fair few wires coming out of it which I think may have something to do with the ignition but I didn't bother tracing them  The reason I need to know is because I tried to get the rev-counter in it to work but when I wired it to the negative side of the coil it didn't work and if it has electronic ignition there is normally a specific feed wire?? So did late Sierras have electronic ignition and if so what colour wire would I need to connect the rev-counter feed wire to? Ps Are Lucas sport coils any good and would I need a ballasted or non ballasted one? |

Not sure on the definitive answer to this - but for a quick check take the dizzy cap to see if you have a set of contacts in there...if you haven't then you've probably got leccy ignition.
I gather you gave your rev counter an earth as well?

I gather you gave your rev counter an earth as well? Yeah the counter has four wires coming from it, and I googled and came up with a rev counter fitting guide which states that, White = Back light (wired to a dash light feed and light works) Red = 12V Ignition (Wired to fag lighter live feed so live on Position 1/2) Black = Earth (Wired to negative battery terminal) Green = Rev counter feed (Wired to negative coil terminal) I will try taking the dizzy cap off and check for points, should have thought of that earlier  |

I've always wired tach's to leccy ignitions to the coil negative and haven't had a problem.
And yeah, the wiring you've been given is pretty much par for the course for aftermarket tach's.

It might depend on your rev counter. Is it a standard rev counter or aftermarket. If its a standard one then it might be expecting a coil feed from a ballasted resistor circuit and they wont work from 12V. I only speak from my experience with my MK1 escort, supposedly there are ways around this but I couldnt find a way to do it.  |

It's an aftermarket one, I bought another one today, one of those huge ones that go up to 11K RPM and have a shift light as well ;D The one in the car at the moment wasn't working when I got it, and I checked and rewired it properly but still no joy  If anyone has got a Sierra Haynes manual lying around can they check it and see what colour the rev counter wire is, I am going to get a manual of E-bay just for the engine part of it so if no one has got one I will have by next week so it's no biggy  |

OK, I'm on it! I had an aftermarket rev counter in my 1600L which was wired to the coil negative terminal and worked fine. Sounds like the same ignition system - is it a fairly flat black box screwed to the bodywork with a little loom coming out? And the distributor has a couple of wires coming out with a multiplug on the end? Not all Sierras had rev counters, and my old chap's P100 didn't (they use that ignition set-up) so there may not be a "factory" wire for it. Shouldn't be a problem though! Will dig out a Haynes manual this morning. |
