yeah, that guy's My reference so far
but since I had 5 wires I kinda wondered, but I'll try the wiring from the amazon dude. if all else fails I'll try finding another one that would work.
Speaking as a fella who worked on various electromechanical and digital flight control and navigation systems in the Air Force, I have never heard of "DV" voltage measurements. If I were to read that in an instruction sheet, I would assume it is a typo, caused by the fact that the "c" and "v" keys are adjacent.
So there would be 2x 12v DC connections on the Tacho if I go by what they give as wiring instructions
It's very possible to have 2 12vdc connections. You still don't know if it's for a dual fire system so even if you get it connected correctly it might not read properly. Good luck
I finally had the chance to try the new cabling configuration I found on the amazon website sor My tacho.
Now they are talking about a high voltage signal.
Where on earth do I find such a wire ??
I tried the input AND the output of both coils and it doesn't budge an inch
I only managed to make the lights go on the darned thing.
( I might have asked though I don't remember)
Thanks in advance
I'm not sure how we can help anymore. I would have tossed that Amazon Chinese junk in the trash by now.
high voltage signal wire is most likely a wire tapped into one of the plug wires...
so I would have to "splice" a plug`s wire to get that high voltage ?
I think all you have to do is wrap that wire around the plug wire. I would not splice it in.
Some of the old and cheapie tachs required you to attach the wire to the spark plug terminal....basically removing the metal tip and crimping another one on with the tach wire included. On an 1100 that'll be fun because it's a special tip.
More modern better quality tachs just let you wrap the signal wire around the plug wire.....
