Hello all, have a question regarding a coil for the GM 3.1,3.4 and many more engines. I am currently in the process of putting it onto a Cub Cadet mower (part is cheaper than Kohler coil and easier to get). My question is which terminal on the back is positive and negative? Thanks!

That'* a loaded request. Are all coils created equal?
Maybe a pic of what you have.
