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 |

i dont know why this is being a problem my tach works fine off of the suby wasted spark, but it is connected to the brain, and that might do the conversion for you. it would be easy enought to make an amp circuit or even a seperate optical trigger to run the tach off the fan hub or flywheel, you could even do a hall sensor with a magnet.
i would think the tach signal from the edis should work the stock tach same kind of signal, its just a grounded pulse. just like a temp sensor just pulsed. |
