12a Trailing ignition help
I'm trying to build a trailing ignition from scratch with only a page or two from the FSM. I need a sanity check from someone who knows how this is wired. Motor is a stockish 12a with the OEM dizzy. I've wired up the leading through an MSD 6AL, so my only concern is the trailing at this point
Here's my current non-working config:
Key-on (+) to "B" terminal on the ignitor, split from there to the (+) on the trailing coil, split again (+) to the condenser.
Ground wire (-) from ground to "C" terminal on the ignitor, split to (-) on the coil.
So far all it has done is pop the key-on fuse when I give it power.
It all seemed sane according to the FSM. Here's the diagram I used to build this config. The circuit I was emulating is outlined in pink.
Can anyone point me in the right direction?

key on "+" to trailing coil "+", "B" on trailing igniter to "+" on trailing coil, coil "+" to condenser, "C" from trailing igniter to "-" on trailing coil. Don't directly ground the coil or igniter. Dizzy housing is ground for the igniter and shares with the coil.

Thanks for confirming that for me. It took a bunch of fuses to figure out that ground was superfluous.
