My old car has a 6 volt electrical system. I have been unable to find a dwell/tach which will work with this vehicle. I was assured by a seller on eBay that the dwell/tach he was selling was compatible (he misread the instructions), but it failed to work on 6 volt, only worked on 12 and I had to return it.

Anyone have this issue? Does anyone know where I can purchase a unit that will work on my car? I even checked with a Snap-On local distributor who said they had nothing available.
