Stock Coil wiring
hey guys i need some help, i think i might have mixed up the wiring on the coil from my dads 74 350 vette. i have a 70 el camino and i thought the coil went out so i took my dads to test to see if mine would fire up... well it didnt and i didnt take a pic or right down what wires went on my dads coil because from what i remmeber only a single green wire was on the negative post and after i put it back it wouldnt turn on....
so heres some pics
is this right?

I'm looking at wire on "-" side of ignition coil looks like distributor might have a Pertronix Ignitor unit inside distributor. If you hooked it up backwards and it is an early Ignitor unit it's DEAD. The Ignitor 2&3 breaker less ignitions won't be hurt by reverse polarity but first design unit will be killed by that act. The question can be answer by popping the distributor cap and looking for points or Ignitor trigger unit.

i believe the ignition module that you linked to is for HEI aftermarket distributors. these dissy's have built-in coils. if you are using the stock coil, you don't need that module, and you may have a unit that replaces the mechanical points with an electronic switching unit. post a pic of what you have.

I think Dads gonna be pi$$ed....
I believe thats a points replacement module....if you in fact wired the coil backwards you can bet its fried....

He won't be too mad he hardly drives it because the drivers seat has a broken bracket and he doesn't like how it moves around while driving. I took some pics of the module but didnt want to disassemble the entire distributor to get a pic of it but it looks like it's a mallory unilite unit, right now the wiring is correct but I believe I did have the wires mixed up at a point so probably next weekend I'm going to test the unit with a multimeter
