Hi Cory, 
         I think we have a terminology problem here. An OBIT is an Oil Burner
Ignition Transformer, has nothing to do with cars, is usually 120VAC in and
23ma -at- 10 kV out. Often used for small ~2-3" diam. coils. I believe what you
are talking about is HEIC High Energy Ignition Coil. These are from cars, are
designed to run on 12VDC batteries, and have small current outputs -at- 10-30kV.
They are usually used for triggered gaps in coiling.
Hope this helps clear up some of it,
