FiTech EFI system
Really? ..........That is the dumbest thing I ever heard. Thanks for the correction.
LOL. Well you have to realize, that in (whenever it was, 1957? 62? 65?) Don't know when "ma" started doing this, "she" wasn't worried about the car being used 50, 60 years later, and certainly not various mods including CDI or EFI
"What that does" is drops all unnecessary loads out while starting the car. You'll notice that the radio and heater goes dead when cranking. Likewise, dropping IGN1 off means that the VR and on newer cars "other things" powered by IGN1 are not loading down the battery on that cold winter night.
Only thing operating is the coil and the starter, "pretty much"
Now that circuit causes the ballast to backfeed from the bypass circuit "back into" everything else during crank, but that current is limited by what the coil resistor can flow, couple of amps, whatever that might be.
