Follow me on this you guys.
My ignition is a Ford EDIS system off of an Escort. (Don't laugh it works) Wasted spark, no dizzy and a 2 coil 4 tower coil pack. The problem is that the 914 tach is triggered off of the negative side of the stock coil and it won't work with the EDIS system. So, I snagged an Escort tach at a pick and pull and I'm going to swap the guts into an extra 914 tach. I just want to verify the connections. It has 3 connectors. Ground and signal in are self explanatory. The 3rd one is labelled B. This has to be switched 12V, right? Thanks Dave |

One would think.
I think it may be possible to use some kind of setup with zener diodes to trigger the stock tach off an EDIS setup, but I haven't thought about it very much - so ... The two signal wires into the coilpack (one on each side I think) represent the negative sides of the two coils, so it may be possible to get a large signal off of it. Alternatively - I wonder if a tach adapter from an MSD would work - they are designed to kick voltage out to old-school tachs. l8r, Fiid. |
